What Parents Should Know About Their Children's Feet
A Guide to Preventing Foot Problems as an Adult
Leonard R. Janis, D.P.M.

Foreword
Parents often ask if their child's foot problem could have been corrected sooner. Frequently, the answer is a resounding "yes." It is important to try to prevent foot problems before they occur. Most adult foot conditions actually begin in early childhood and progress as the child grows. Parents generally do not notice problems with their child's feet, so conditions that could have been prevented or corrected early never are properly evaluated or treated. When one finally does notice a foot condition, it can be too late to treat conservatively.
My experience, in more than 25 years of treating foot, ankle, and leg conditions, is that a great many of children's foot and leg problems are neglected. Some are obvious such as, a club foot, a child who has a severe intoeing gait, or infected ingrown toenails or warts. The parent notices these immediately and seeks out a competent member of the medical community for appropriate treatment. However, most other conditions which the parents think will go away or is reassured that the child will outgrow the problem, unfortunately continue into adulthood. Although some of the conditions will improve with time, most do not. The child, then, doesn't get any treatment. It is no wonder that 70% of all adults report some type of foot problem.
A complete history and physical examination will determine whether there is a problem, why the problem exists, ways to treat it, and any benefits or risks. What Parent's Should Know About Their Children's Feet provides information parents need to know to make informed choices regarding their children's foot health. Having this information will lead to a better understanding of common foot and leg conditions and their appropriate treatments from birth to adulthood.

Growth,
Anatomy & Development
Growth and Development
The average newborn weighs 7
to 7 ½ pounds at birth
and is approximately 20 inches
long. Growth is fairly rapid
until age two, and then starts
to slow until puberty. The growth
rate in boys and girls is fairly
equal until puberty, then the
rate accelerates. Girls usually
develop two years ahead of boys.
After puberty, at approximately
age 16 in girls and age 18 in
boys, growth ceases. Typical
"growing pains" are
associated with the normal growth
of the child due to differences
in growth rate, and pressure
of different structures as they
grow.
At birth, a child's legs are relatively
short when compared to the overall
length of the body. From six
months of age until puberty,
the legs grow more rapidly,
until the growth plates start
to close.
Statistically, most people have
one leg longer than the other.
The right leg is slightly longer
than the left 70%-75% of the
time. The left foot is slightly
longer than the right, although
the right foot is somewhat broader.
The foot doubles in length from
birth to age four. It increases
in size almost one centimeter
per year. At age 10, girls reach
90% of their foot growth, boys
reach approximately 80%. By
age 14, most girl's feet have
stopped growing, whereas growth
stops about 16 years of age
in boys.
When an infant is born, its legs
are rotated outward. In fact,
there is twice as much rotation
outward as there is inward.
The femur, or thigh bone, and
the tibia, the lower leg bone,
untwist as growth occurs. Therefore,
it is most important to know
and to understand what is considered
not normal. Conditions such
as bowlegs, knock-knees, and
walking up on the toes are acceptable,
depending on what their developmental
status is.
The same holds true with flat
feet. A flattened foot structure
where there is no arch is not
abnormal in the first two years
of life. We will discuss these
conditions later in greater
detail. Again we need to know
what the normal foot structure
is in order to make appropriate
decisions as to when the child
will either outgrow the condition
or needs treatment.

Anatomy and
Development
At birth there are relatively
few bones in the foot. As the
child matures, new areas of
bone growth appear until the
foot stops growing. By examination
and taking an x-ray picture
of the foot we can determine
the physiological growth (maturity)
as compared to the chronological
growth (age) of the patient.
Knowing this information helps
determine whether treatment
is necessary.
There are two very important "laws
of nature", that determine
the final outcome of how normal
our feet will be later in life.
The first applies to how bones
grow, the other to soft tissues,
such as muscles, tendons, and
ligaments. Basically, the size
and shape of any structure,
be it bone or soft tissue, is
determined by the amount and
direction of pressure applied
to it. If the structure is allowed
to grow normally it will do
so. If abnormal pressure is
applied as growth occurs, such
as a poorly fitting shoe, the
structures will change and grow
abnormally.
Hereditary factors can and do
play an important role in how
we develop. If a child's grandparents,
father, and mother have flat
feet, it would be highly likely
that the child will also have
flat feet. This may be normal
because it is a hereditary condition,
and the parents should not be
overly concerned. However, not
all conditions can be blamed
on hereditary factors. In addition,
even if there is a strong hereditary
background, it does not mean
that the condition should be
neglected or left untreated.

When to Examine
for Problems
Every newborn should be examined
carefully for any potential
foot or leg problem. These are
usually easily diagnosed and
are associated with congenital
abnormalities such as clubfoot,
overlapping toes, syndactaly
(web toes), polydactaly (extra
toes), or congenital dislocated
hip. This is done by the physician
in the newborn nursery where
any limitation of motion or
obvious problem can be evaluated
and quickly treated.
Another examination of the feet
and legs should be done at four
to six months of age. This is
the age at which most children
try to stand and then begin
to walk. A child can usually
walk unassisted by 10-14 months.
Most conditions associated with
flat feet, bowlegs, knock knees,
leg length differences, and
ankle problems become obvious
with standing. Hopefully, parents
will follow the examination
recommendations very carefully.
This will help identify and
allow treatment of most conditions
without letting them get too
advanced. An annual checkup
or an examination at least every
two years after age 10 is essential
for proper foot care and prevention
of problems.
(back to the table of contents)
Foot and Leg
Functions
Basically our feet and legs
function to do three things:
provide support for the rest
of the body, absorb shock, and
adapt to the surface which we
stand on.
The lower extremities are divided
into three segments: the foot,
ankle, and leg. It is the foot
and it's many bones, ligaments,
and tendon structures that acts
as the foundation of support.
The foot is uniquely designed
to absorb shock and adapt to
allow for proper function. Studies
have determined that this marvelous
structure works by changing
the angles of how it strikes
the ground and how each of its
individual bones line up and
when. The heel should be straight
up and down and the bones in
the ball of the foot should
hit at the same time when the
foot his he ground. If for example,
this alignment is off, the foot,
ankle, and leg will get out
of alignment and not function
properly. Structural changes
then occur that lead to foot
and ankle problems and to potential
deformities.
The ankle and foot work together
as a unit. The foot allows for
motion to occur mostly side
to side, whereas the ankle allows
for the motion to occur up and
down. Both of these motions
are converted into rotation
or twisting motions that is
taken up into the leg. All three
of these structures, the foot,
ankle, and leg, must work together
to insure proper function.

Common Conditions
Found at Birth
Congenital Dislocation of the
Hip
Definition: Congenital dislocation
of the hip (CDH) is a condition
where the head of the femur
(thigh bone) is dislocated out
of the hip joint.
Congenital dislocated hip is caused
by abnormal position in the
uterus or a problem with development.
It is eight times more common
in girls than boys, with the
left hip being six to eight
times more involved than the
right. There is a strong family
predisposition, usually running
20%-30%. The condition is characterized
by looseness or laxity of the
joint with one leg being shorter
compared to the opposite leg.
A "clunking" noise
may be heard when pulling on
the leg and then letting go,
as it snaps back. It is easily
diagnosed by examination and
x-rays.
Treatment: Treatment is successful
when initiated early. Typically,
either double diapering, splints,
or braces, can relocate the
bone and it will heal uneventfully.
Surgery is rarely needed.
(back to the table of contents)
Club Foot
Definition: Club foot is fairly
common seen with a frequency
of 1 per 1,500 births. It is
a condition where the foot is
held inward and upward in relation
to the leg. Some club feet are
fairly mild and flexible in
nature while others are quite
rigid and stiff.
Treatment: The treatment of choice
is a series of foot casts done
immediately after birth. This
will manipulate the foot back
into its normal position. Statistically,
however, a club foot condition
will require some type of surgery
70% of the time.
(back to the table of contents)
Reverse Club
Foot (Calcaneal Valgus)
Definition: The reverse club
foot deformity is seen at birth
and is more frequently found
than clubfoot. It occurs in
1 per 1,000 births. It is caused
by improper intrauterine positioning
and is easily recognized at
birth. The entire foot is tilted
upwards and can actually touch
the front part of the lower
leg. It is more commonly seen
in girls and first-born children
because of a tight fit in the
mother's uterus.
Treatment: Unlike clubfoot, the
treatment is relatively easy
and the results excellent without
surgery. The use of casts and
braces are all that is needed.
(back to the table of contents)
Rocker Bottom
Foot
Definition: A rocker bottom
foot is a very rigid flat foot
where there is absolutely no
arch. In fact, as the name applies,
the "arch" area of
the foot looks like the rocker
part of a rocking chair. It
results when the keystone bone
that supports the arch inside
the foot becomes dislocated
out of position. This is usually
due to improper pressure inside
the uterus.
Treatment: This type of foot problem
is highly resistant to any type
of casting, manipulation, or
conservative care. Surgery is
usually the treatment of choice.
(back to the table of contents)
Metatarsus
Adductus (Turned in Foot)
Definition: The turning in of
the front part of the foot (metatarsals)
is one of the most frequently
seen conditions in newborns.
It is sometimes confused with
or associated with being pigeon-toed,
which is really a leg rotation
problem. Metatarsus adductus
frequently affects both feet,
although only one foot may be
involved. The outside border
of the foot is characteristically
"c" shaped, and the
toes point inward.
Treatment: There are two types
of metatarsus adductus: flexible
and rigid. The flexible type
can be easily straightened and
treated with casts or special
shoes. The rigid type is far
more stubborn. If conservative
care fails, surgery would be
required.
(back to the table of contents)
Overlapping
Toes
Definition: This condition is
almost the rule rather than
a real problem. That is, it
is commonly seen in newborns.
The most frequently involved
toes are the second toe which
overlaps the third. Equally
as common is the inward rotation
of the fifth toe overlapping
the fourth. Overlapping is mentioned
here only to note that it is
very commonly seen and is not
really a problem in most cases.
Treatment: Normally no treatment
is needed as it is a condition
that will be outgrown. Simple
taping of one toe to another
is usually all that is needed.
(back to the table of contents)
Webbed Toes
(Syndactaly)
Definition: Webbed toes are
another common and harmless
condition. There is an absence
of the web space between one
or more of the toes. The web
space may be either partially
or completely filled in. This
condition while not harmful,
may cause some concern from
a cosmetic point of view.
Treatment: No treatment is needed
unless it is severe and involves
all or most of the web spaces.
Cosmetic surgery could then
be performed if requested.
(back to the table of contents)
Extra Toes
(Polydactaly)
Definition: Extra Toes are fairly
uncommon and may involve one
or both feet. Sometimes there
are two big toes, other times
an extra small or duplicate
toe. While not a serious problem
it usually affects the child's
ability to wear shoes and certainly
is a cosmetic problem.
Treatment: The treatment for an
extra toe is surgical removal.
(back to the table of contents)
Long Toes
or Short Toes
A common concern of parents
regarding their children's feet
is the length of the big toe
compared to the second toe.
The big toe may be longer or
shorter than the second toe.
When it is shorter it is called
a Morton's foot and is characterized
by a short first bone in the
ball of the foot (metatarsal).
The toe only appears to be shorter
because it sits on a bone in
the ball of the foot that is
short. This type of foot tends
to pronate or flatten and is
associated with the formation
of callouses.
When the great toe is longer than
the second toe, the first bone
in the ball of the foot is longer.
This type of foot can form a
skin callous directly beneath
the first bone and contracted
toes or hammertoes. Besides
the great toe, the other toes
may be affected. The cause is
the same, a short metatarsal
bone.
Treatment: It is of little concern
whether the great toe is longer
or shorter than the second toe.
There is no treatment.

Common Leg
Conditions During Early Childhood
Intoeing (Pigeon-toed) / Out-toeing
(Duck or Slue footed)
Definition: When a baby is born
there is normally two times
as much outward rotation of
the legs as compared to inward
rotation. As the child grows
this unequal rotation gradually
begins to even itself out with
the end result being an equal
amount of inward and outward
rotation. Pigeon-toed (inward)
or slue-footed (outward) feet
positions are fairly common
in infants and toddlers with
one leg usually affected more
so than the other. However,
both legs can be affected. The
condition of intoeing or out-toeing
results from involvement of
a variety of soft tissue or
bony structures or a combination
of both. It may involve the
hip, upper leg, knee joint,
lower leg, ankle, or foot. A
thorough examination is mandatory
to determine the exact cause
of the condition. Only then
can it be decided whether the
condition will be outgrown or
needs treatment. The earlier
it is diagnosed the better.
It is unfortunate that parents
are told their child will outgrow
the problem, only to find out
later that the condition still
exists and would have responded
well to treatment at a much
younger age.
Treatment: Fortunately, well over
90% of intoeing/out-toeing conditions
will self correct as the child
grows. Mother Nature helps to
rotate the legs around properly
during three periods of the
child's rapid growth: 1-3 years,
5-7 years, and during puberty.
By age 10-12 only 4% of these
types of problems still exist.
Treatment depends on the age of
the patient. If detected early,
simple changes in sitting or
sleeping habits is all that
is needed. The habit of sitting
in a frog-legged style should
be avoided. Sometimes a night
splint may be used or even leg
casts.
If the condition is left untreated
until the child begins to walk
it becomes more difficult to
treat. The soft tissues shorten
around the hip and the knee
joints have already begun to
tighten up in the wrong position.
Simple non-painful braces worn
during nap time or special supports
that can be used during walking
also can be used successfully.
It is rare that more aggressive
treatment is needed unless the
child trips and falls frequently
or has chronic pain.
(back to the table of contents)
Bowlegs/Knock
Knees
Definition: At birth it is normal
for the child to be bowlegged.
The legs are not straight at
this age. There is a normal
progression of development of
the legs. The legs are bowed
from birth to age 2. They then
become straight but become knock-kneed
again from age 2 until age 4.
From age 4 to about age 7 the
process again reverses itself
until they are basically straight.
Often bowlegs/knock-knees are
associated with flat feet. This
will be discussed is a separate
section. Bowleg conditions often
look worse than they actually
are. This is because the soft
tissue structures of the calf
area are rotated to the outside
of the leg making it appear
more bowed. As the child grows,
this apparent bowleg appearance
reduces and goes away.
There are some very rare conditions
(rickets, Vitamin D deficiency,
and bone growth abnormalities)
that need to be ruled out in
some cases. Both legs are usually
affected. If only one leg is
affected it may be due to some
other problem such as laxity
of the ligaments in the knee,
a hip problem, or significant
difference in the length of
the legs.
Treatment: Most treatments associated
with these conditions are actually
directed at supporting the foot
structure to keep the arch from
falling. As previously described,
since most of the time the problem
self corrects, no treatment
is needed. However, if needed,
appropriate casts and/or braces
can make a significant difference.
Surgery is rarely indicated
unless the child has a severe
problem that has not corrected
or greatly improved by conservative
treatment.
(back to the table of contents)
Hyper-Extension
of the Knees
Definition: Also known as genu-recurvatum,
this condition looks like the
knees are actually bent backwards.
It is often seen with excessive
laxity or hypermobility of the
soft tissue structures (muscles,
ligaments) that support the
knee joint. When standing the
pressure on the knees from the
child's weight makes it more
apparent.
Treatment: Fortunately this condition
almost always self corrects
as the child matures. The best
treatment is to do exercises
that strengthen the muscles
around the knee joint or use
braces that help stabilize the
knee. If left untreated, the
laxity can result in arthritic
changes in the knee joint.
(back to the table of contents)
Leg Length
Differences
Definition: Numerous studies
have determined that almost
90% of the population has a
difference in the length of
their legs of up to ¼
of an inch. Therefore, it is
not necessarily abnormal to
have a leg length difference.
However, measurements must be
made to determine if a leg length
difference is an influence on
the total condition of the patient.
For example, a child with a
problem with their right knee
or a low arch only on the right
foot may have a faulty foot
structure influenced by too
long a leg on the right side.
In an attempt to help equalize
and straighten the body, the
arch of the right foot may have
lowered to compensate. Conversely,
the arch of the left foot may
attempt to lift up. An additional
way for the body to compensate
is for the foot on the long
leg side to rotate more outwardly.
While 90% of the time one leg
is longer than the other, 80%
of the time the symptoms or
problem will be located on the
long leg side. This is because
there is more pressure on the
long leg side. Subsequently
the foot and leg structure has
to give more. Symptoms frequently
seen on the long leg side are
inside arch problems, inside
knee pain and shin splints.
Conversely, on the short leg
side we often see symptoms of
outside foot problems, problems
on the outside portion of the
knee, upper leg and lower back
symptoms. These are generalizations,
but they are true most of the
time.
Differences in leg length are
due to four variations in structure
or combinations of all four:
bone to bone length, how the
bones are situated in the soft
tissue (muscle tightness), combinations
of both, or from the foot structure.
Treatment: Different types of
doctors treat the problem in
different ways. Some do not
feel there is a real problem
with one leg longer or shorter
than the other unless the difference
exceeds more than ½ an
inch.
In my opinion, I look at the condition
as only one part of the entire
examination. Treatment depends
on whether or not the difference
in length is significant and
how it may help as part of the
overall treatment plan. In many
instances, no treatment is needed.
However, if treatment is warranted,
just adding a lift to the short
leg side is usually not enough.
It is necessary to treat the
entire foot and leg length as
a unit. Therefore a lift on
the short leg side is commonly
incorporated into an arch support
to support and cushion the foot
while equalizing the leg length.
Additionally, the leg length
difference must be rechecked
after treatment and at regular
intervals, at least every 6
to 12 months. This is because
with appropriate treatment the
difference can actually change
or even resolve. If the lift
therapy is continued too long,
it may adversely affect the
foot or leg structure and cause
continued pain.
(back to the table of contents)
Tight Heel
Cord (Equinas)
Definition: The calf muscles
by way of the Achilles tendon
attach to the back of the heel
bone. Besides helping to push
the body forward when walking
and running, they also act to
hold the outside part of the
foot firmly on the ground. If
the Achilles tendon is too short,
it puts tremendous and excessive
pressure on the structure of
the foot. In fact, a tight heel
cord is a major contributing
cause of childhood flat feet.
That is, the tight heel cord
forces the foot to break down
and flatten. In rare instances,
the foot doesn't break down
and the child then literally
has to walk up on their toes.
The heel never really touches
the ground.
Treatment: Stretching exercises
are sometimes effective if the
amount of tightness is not to
severe. However, exercise must
be done properly so as not to
further affect the foot and
continue to lower the arch.
A lift inside the shoe can be
used to bring the heel up to
the proper height and take pressure
off the tendon. Although rare,
surgery can be used to lengthen
the heel cord. This procedure,
while highly successful, is
usually done in combination
with other procedures to correct
any abnormal foot structure.
(back to the table of contents)
Night Cramps
Definition: Often a child will
wake up at night and complain
of pain and cramping of the
muscles in the legs, specifically
the calf muscles. This generally
occurs in children who are very
active during the day. The cause
of this is thought to be associated
with a flatfoot structure and
tight heel cord. These can cause
an overuse of the muscles in
the lower leg which results
in a buildup of waste byproducts
from muscular activity. During
activity, the child's muscles
contract and dispose of these
byproducts. At rest the byproducts
can buildup and are not eliminated
from the muscles. The child
then complains of pain in their
legs.
Treatment: Massaging the legs
helps to rid the tissues of
the buildup of byproducts and
helps relieves the pain. It
is best to prevent the problem
in the first place by providing
a rest time before bedtime,
as well as a soothing bath.
In resistant cases, orthotics
(custom-designed arch supports)
or medication can be used. Regardless,
the problem resolves as the
child matures.
(back to the table of contents)
Low Arched
Feet (Flat Footed)
Definition: There are three
types of foot structures: normal,
high arched, and low arched
or flat feet. Flat feet are
further divided into three types:
the mild type in which the arch
is still visible when the weight
is on the foot, the moderate
type in which, with weight on
the foot, the arch is not visible,
and the severe type in which,
with weight on the foot, not
only is the arch not visible
but the area on the outside
border of the foot looks "c"
shaped.
Mild low arched feet are very
common. It is estimated that
70% of the general population
has a tendency toward excessive
rolling in of the foot. This
can lead to a formation of painful
bunions, hammertoes, callouses,
heel spurs, tendon injuries,
and leg and back problems as
an adult. Children rarely complain
of pain, but often present with
chronic leg fatigue, night cramps,
appear clumsy, trip or fall,
or have uneven shoe wear.
Most children never show an arch
in their feet until they are
18-24 months old. This is because
there is a normally occurring
fat pad that occupies the arch
and fills in the normal contour
of the foot. An important difference
in the flat foot of a child
as compared to that of an adult
is that much of the foot structure
in the child is still cartilage
which continues to develop until
adulthood.
Much of this structure develops
by age six. Therefore a low
arched foot even up to this
age is not necessarily abnormal.
However, when walking begins
between the ages of nine and
eighteen months, pressure on
the foot structure and its cartilage
can adversely effect how the
foot forms. Therefore, an examination
of the foot very early and again
just when the child begins to
walk will help determine if
any problems exist and whether
treatment is advisable.
Most flat feet are flexible or
non-rigid. While standing, if
the foot flattens in the arch
area and then without weight
bearing looks normal it is the
flexible flat foot type. Non-flexible
or rigid flat feet show no arch
with or without weight bearing.
This type of foot usually is
seen with a condition called
tarsal coalition.
Tarsal coalition, a condition
in which there is an abnormal
connection between two bones
of the foot. It can be either
soft tissue, or a bony connection.
Because of the flexibility of
the cartilage and fibrous connections,
this problem is rarely seen
until the age of 10 to 13 years.
At this age the soft cartilage
in the foot changes and becomes
bone. If a rigid connection
forms it prevents the foot from
moving properly. It is often
associated with tightening of
the muscles on the side of the
leg. These muscles eventually
go into spasm and the foot becomes
locked into position (peroneal
spastic flat foot). Fortunately
this condition is rare and is
seen in only one to two percent
of children. It also seems to
affects boys much more commonly
than girls.
Treatment: There are 3 treatment
options depending on the child's
age and degree of problem: special
shoe modifications, orthotics
(custom designed arch supports),
and surgery. Knowing what, or
what not to do, and for how
long, is critical to a successful
treatment outcome. Since these
treatments can be used for other
conditions than flat foot, they
will be discussed individually
later.
Remember though, flat feet should be evaluated very
early, beginning at seven to nine months of age or when
the child begins to walk. Unfortunately, most people
think little can be done to correct flat feet. This
misconception is from a lack of understanding of the
problem. Attention to proper treatment will encourage
normal development.
(back to the table of contents)
High Arched
Feet
The arch of the foot, if too
high, does not absorb shock
well nor does it adapt to the
ground like a normal foot would
do. Fortunately, the excessively
high arched foot is infrequent.
Because it can be associated
with neuromuscular diseases,
it is important to obtain a
thorough family history with
possible examination of other
family members.
High-arched feet have basic
characteristics associated with
them, such as rigid hammertoes,
painful and thick callouses,
heel spurs, frequent ankle sprains,
and a tight heel cord. The toes
often contract upward. They
can raise so high that it pulls
the protected fat pad forward
and away from the bottom of
the ball of the foot. This results
in considerable pain in the
ball of the foot and arch.
High-arched feet do not respond
well to conservative care. When
an orthotic is used in treatment,
it must be constructed with
very soft and shock absorbing
materials. Frequently, severely
high-arched feet make it impossible
to wear shoes or walk comfortably.
Surgery, when indicated, is
directed at correcting the many
different toe, metatarsal, midfoot,
heel, and tendon problems associated
with high-arched feet. The surgery
often needs to be staged, that
is, divided into several different
operations because of it's complexity.
It is also common to fix only
one foot at a time. The surgery
to correct a high-arched foot
repositions and realigns the
bones and tendons of the foot
structure therefore allowing
for proper function.

Conservative
Treatment Methods
Shoes and Shoe Therapy
Before we discuss "corrective"
shoes, it is important to look
at some of the standard recommendations
for shoes by the shoe industry
for each age group.
Infants generally should wear
high top shoes with a soft,
flexible bottom or sole. The
only reason for a shoe at this
age is for protection. Until
18 to 24 months of age, the
high top shoe is used to merely
hold the shoe on more securely.
It does not truly support the
ankle nor restrict motion of
any kind. The soft, flexible
sole allow the child's soft
foot structures plenty of room
to move and grow.
The oxford type "low top"
shoe is best used as soon as
the child begins to bear weight
and then begins to walk. The
low top allows for needed ankle
motion. It not only affords
protection for the foot, but
more importantly provides a
firm flat surface. The foot
can function more correctly
when on a flat surface. Therefore
the shoe should also have a
rigid shank. A rigid shank is
where the sole of the shoe is
reinforced from the heel to
just in back of the bones in
the ball of the foot. However,
at the ball area, the shoe needs
to be quite flexible. The correct
size should be frequently checked
as the child's foot grows rapidly.
Generally, a small raised heel
helps prevent excessive wear
and tear on the shoe. Leather
is the preferred material. It
is flexible, wears well, and
most importantly, it breathes.
Children's feet readily perspire.
The leather allows moisture
to pass through and evaporate
easily. Natural cotton socks
are excellent to help absorb
perspiration.
Athletic types of shoes (tennis
shoes) are fine to wear but
are best reserved for times
when the child is involved in
very active or sporting type
activities. Most parents have
a tendency to allow the child
to wear this type of shoe all
of the time. While not considered
the best choice for the foot
structure, with today's construction
methods, materials, and shoe
industry technology, wearing
this type of shoe is a close
second choice and perfectly
acceptable. The most important
and best quality of athletic
shoes is their ability to absorb
shock. Be careful not to buy
very cheap shoes. They cost
less in general because they
do not have the quality materials
nor the proper construction
needed to support the foot.
They frequently do not last
very long either. You always
wind up buying shoes more frequently
than really needed.
A word about other popular type
of shoes: sandals made with
a good arch support that do
not cause irritation are fine
during warmer weather; flip-flops
other than for use at the pool
are not recommended. Moccasins
do not provide any support and
only a minimal amount of protection.
They should be avoided. Patent
leather Mary Janes for the occasional
dress up time are acceptable.
However, they should not be
worn for any extended period
of time. The patent leather
does not breathe and is frequently
lined with a nylon type material.
Children can develop friction
burns on the skin of their feet
from this type of shoe.
"Corrective Shoes" for
various types of foot problems
have been around for years and
are widely recommended by all
types of doctors. Surveys have
indicated many pediatricians,
podiatrists, and orthopedic
doctors routinely prescribe
"orthopedic" or corrective
shoes. However, there is little
evidence to justify using shoes
to correct most foot problems.
Shoes can be a valuable indicator
of some type of foot problem
when they wear abnormally or
there is a noticeable gap between
the foot and shoe.. But the
problem with corrective shoes
is that the foot moves within
the shoe and could not possibly
hold the foot in the desired
position to really correct it.
Although shoes as a correction
do exert some small measurable
affect, most of the time the
problem should not have been
treated in the first place,
or it corrected itself as the
child grew. The shoe itself
did very little.
Some shoe types and certain modifications
are valuable to use in rare
instances, and only for a short
period of time. For instance,
while it is best to cast an
infant's foot when there is
a problem, sometimes an open
toed shoe can be used to realign
a problem or help hold it in
place.
Arch cookies, like corrective
shoes, do little to alter a
flat foot or other foot problem.
Studies have determined the
end result to be the same whether
arch cookies were used or not.
Remember, shoes are a necessity
to protect and support the foot
structure and to help absorb
shock. We walk an average of
70,000 miles in a lifetime.
Good shoes will help ensure
our feet will last a lifetime.

Orthotics
(Custom Designed Insoles)
Orthotics are used for children
to do three things: control
and balance how the foot functions,
to help correct a foot problem,
and to aid in preventing a foot
problem from getting worse.
In an adult, an orthotic will
not really correct anything
that already exists or has occurred
since birth. It acts more as
an accommodation.
What is an orthotic? It is a custom
designed foot support. It is
not an arch support. Orthotics
help to balance the front and
back part of the foot structure
to keep it in alignment with
the ankle and leg. The arch
is only secondarily affected.
An arch support appears to help
the arch because it pushes up
on the soft tissues. When the
support is removed the arch
of the foot simply flattens
back down. An orthotic balances
the foot structure and allows
for growth in a proper alignment.
When growth has been completed,
the orthotic can be discontinued,
and the foot structure, now
normal, will remain in the proper
position.
Remember that initially, almost
all children's feet pronate
or appear to roll in. When they
begin to walk, usually at age
10 to 15 months, their feet
will look flat. If the doctor's
examination determines an abnormal
foot condition, treatment is
best begun at that early age.
Also recall that many foot problems
can be influenced by intoeing
and out-toeing. If these are
present in addition to a foot
condition, treatment is needed.
While there are literally hundreds
of different styles of orthotics,
there are really only two types:
rigid and soft. Soft orthotics
are generally reserved for adults
who not only need control of
their foot structure but cushioning
as well. Children almost always
require rigid orthotics. Do
not confuse rigid or hard orthotics
with discomfort. When made properly
an orthotic is very comfortable.
Orthotics for children need
to be made of rigid materials
to control and balance the foot
structure best.
How is an orthotic prescribed
and then made? First, your doctor
will perform an examination
and determine if an orthotic
is needed for your child. The
type of device will then be
determined and a cast impression
of the foot is made. This is
done in a variety of ways. Regardless
of the method, it is painless.
The foot is held in the correct
position, and an exact copy
of the foot is made. The impression
cast is then filled with plaster.
When dry the result is a mold
of the child's foot. Plastic
materials are then used to fabricate
the orthotic device over the
mold.
A word about taping. Sometimes
tape is used to help support
the foot structure to see if
an orthotic will be beneficial.
While sometimes appropriate
in an adult, there is no reason
for this type of treatment with
a child.
What about over-the-counter arch
supports like those sold in
stores. Orthotics are like eyeglasses.
If you need an orthotic, it
needs to be your own. Over-the-counter
or prefabricated devices only
rarely work and should not be
used.
A child's orthotic, to be effective,
needs to be worn all the time.
That means orthotics and shoes
should be worn all the time
except when taking a bath or
sleeping. While this may sound
like a lot, think of your child
wearing braces on their teeth
for 24 hours a day. An orthotic
can only work when it is worn.
If it is used off and on, the
results of the therapy will
be less than satisfactory. Or
course, orthotics can be switched
from one pair of shoes to another.
Parents must remember that it
takes time for the effectiveness
of an orthotic to be judged.
It is not a short term therapy.
It is used at least for a period
of one to two years and can
be utilized past puberty. Generally,
in a growing child, new orthotics
will be needed every two to
three years or four to five
changes in a shoes size.
Most children can wear their orthotics
right away and do not require
a break-in period, although
some children will need to break
their orthotics in gradually.
If the child complains of pain
or discomfort, or develops blisters
or areas of irritation from
the orthotics, consult your
doctor immediately. Sometimes
the device will need a minor
adjustment.
Socks should always be worn with
orthotics. If the child's foot
perspires excessively, lightly
dust the inside of the shoe
with talcum powder, or spray
the feet with underarm spray
deodorant with an antiperspirant
in it. This is an easy and inexpensive
way to reduce excessive perspiration.
Orthotics function best in a
good pair of shoes. If the shoe
is excessively worn down, it
will not allow the device to
work properly.
An orthotic functions to bring
the ground up to the foot rather
than the foot going through
abnormal motion to contact the
ground. They can be quite effective
when used correctly in treating
many children's foot problems.

Common Childhood
Nail and Skin Problems
Nails
Infants are born with paper
thin nails. They need to be
trimmed often to prevent babies
from scratching themselves.
Fortunately, infants and toddlers
rarely have troublesome nail
problems. If they do, it is
an ingrown nail caused by an
injury such as dropping a heavy
object on the toe.
Ingrown nails are best treated
by prevention. That is, proper
trimming either straight across
or slightly rounded will help
the nail sides from developing
hooks on them which can become
ingrown with subsequent infection.
If such a problem does occur
in a very young child, most
often it can be treated successfully
with local measures, such as
topical antibiotic creams and
soaks. Because the nails are
very thin and pliable, conservative
care until the nail grows out
is usually sufficient. If not,
there are several minor surgical
procedures that can be performed
in the office with excellent
results. However, it is important
to treat an ingrown nail as
soon as it occurs. A chronic
infected nail can lead to other
more serious problems.
If a child unfortunately drops
something on their toe, it can
cause bleeding underneath the
nail, and it is very painful.
The blood that collects underneath
the nail plate itself makes
the nail look very dark blue
or even black in color. It is
best to seek the advise of your
doctor when this occurs. It
may be necessary to make a small
hole in the nail to let the
blood come out in order to alleviate
the pressure underneath. Sometimes
the whole nail must be removed.
It almost always will grow back
normally. An x-ray picture may
be needed to make sure that
there is no injury to the underlying
bone.
(back to the table of contents)
Warts
Warts are caused by a virus.
Mostly seen in young children,
they are often seen on the feet
in numerous locations. When
they occur on the bottom of
the foot, they can be easily
confused with other skin conditions
such as a callous or cyst. It
is important to identify it
as a wart so as not to treat
inappropriately.
Characteristically, a wart will
have small dots or seed-like
markings, whereas other lesions
do not. These "seeds"
are really the ends of very
tiny blood vessels called capillaries,
which provide the blood supply
o the wart and helps it to grow.
There may be just one wart or
many. Permanently getting rid
of warts may be exceedingly
frustrating. There are many
different treatments for warts,
ranging from the simple over-the-counter
medications to advanced laser
techniques or surgery.
In young children, it is best
to use the simplest and easiest
treatment which is an over-the-counter
acid preparation. The child's
foot is soaked in warm water
for two to three minutes, gently
rubbed with a washcloth, and
then acid is applied to the
wart area two to three times
as day for two to three weeks
or until the wart is gone. If
a new wart appears, or there
is a recurrence of the old wart
(up to 30% of all warts re-grow),
the process is repeated.
When the medications are used
as directed, they are usually
successful. However, if this
fails, other types of wart treatments
can be attempted. Surgical removal
is an option but is mostly reserved
for warts resistant to conservative
care or in very difficult cases.

Foreign Bodies
Unfortunately, children occasionally
step on a sharp object such
as a needle or sliver of wood.
Most of the time, it can be
easily removed, the area cleansed,
and healing is uneventful.
Obviously, the best protection
against stepping on sharp objects
is to make sure your child wears
shoes as much as possible. This
not only helps prevent an accident
but helps the foot structure
to grow better because it is
supported and balanced.
(back to the table of contents)
Fungus Infections
Commonly referred to as athlete's
foot, it is rare to see this
fungal infection in children
under the age of three. It is
much more prevalent after the
age of four. The fungus likes
to grow in a dark and moist
environment.
Parents frequently ask if the
fungus can spread from one child
to another. It is not really
contagious like a viral infection.
Just because one member of the
family has the fungus infection
does not necessarily mean anyone
else will get it. Certainly,
standard precautions such as
wearing clean socks and shoes
and avoiding direct contact
are advisable.
Fungus infections present themselves
in several different ways. There
may be a small area of redness
between the toes, there may
be many small water blisters
which itch and look like a rash,
or a combination of all of the
above.
Typically, treatment is straightforward
and simple. The feet should
be kept dry and good quality
shoes used. Almost any over-the-counter
anti-fungal medication will
cure the problem. Remember to
use an underarm antiperspirant
spray on the feet two to three
times a day if the child perspires
excessively. This will help
control the sweating. If the
problem is very resistant, consult
your physician for prescription
medication. Remember, some fungal
infections may never really
be totally cured. They may recur
over and over again, even with
treatment.
(back to the table of contents)
Contact Dermatitis
A fairly common childhood problem
is an allergic reaction to any
number of products used in the
construction of a shoe. The
materials and glues can react
with the skin and cause it to
get red and inflamed. The great
toe and sides of the foot are
usually affected first. The
spaces between the toes are
rarely affected.
The best treatment for contact
dermatitis is to identify the
cause of the irritation and
remove it immediately. After
that, various types of over-the-counter
cortisone creams are used to
reduce inflammation. If itching
needs to be controlled, Benadryl@
can be obtained at any drugstore.
(back to the table of contents)
Impetigo
Impetigo is one of the most
common skin problems seen in
children. It is a bacterial
infection that at first looks
like small pimples on the skin.
It frequently affects the face
although it can be seen on the
feet. When the small lesions
rupture, the contents of it
dry and form a crust. It usually
is short lived and heals quickly
by bathing, removal of the crusts,
and good skin care. Typically,
if localized, antibiotic ointments
are often helpful in controlling
its spread and in healing the
problem.
(back to the table of contents)
Eczema
Eczema is a very common term
used by doctors for a variety
of skin conditions. It is not
really a disease at all, but
a condition of the skin which
can have many different causes.
It is characterized by the inability
of the skin to refrain water
normally. Little blisters of
sweat form. These itch, and
the subsequent scratching leads
to problems. The skin is typically
swollen and develops small pimples
or crust. It is seen on the
face, scalp, arms, and legs.
It is usually the result of
using perfumed soaps, oils,
or powders applied to the infant's
or child's tender skin. Non-allergenic
products are best used to avoid
this generalized skin condition.
(back to the table of contents)
Psoriasis
The cause of this disease is
unknown. It is characterized
by patchy areas of silvery or
pearly scales frequently seen
on the elbows and knees. It
is frequently confused with
a fungus infection on the feet.
Although seen in infants, it
is most commonly seen in children
over the age of three. On the
foot it can affect the nails
and appear as tiny pits on the
nail itself. If a skin scale
is gently lifted up, there will
be a small bleeding point underneath
it. This is almost a sure sign
that confirms the disease. It
is best to have your pediatrician
treat this condition.
(back to the table of contents)
Foot Odor
If the child's feet smell, it
is the result of excessive sweating.
The foot becomes secondarily
infected with bacteria which
causes odor. This is a very
common problem, usually from
not wearing socks with shoes.
The socks act to absorb the
perspiration thereby eliminating
the environment for the bacteria
to grow in the first place.
As previously discussed the
use of foot soaks or underarm
antiperspirant sprays on the
feet usually resolves the problem.
Over-the-counter products that
help eliminate the odor are
also effective. If the shoe
also has a foul odor, they must
be washed or thrown out and
new ones purchased.
(back to the table of contents)
Corns and
Callouses
A corn is an area of thick skin
on a toe. A callous is an area
of thick skin on the ball of
the foot. They can start as
simple skin irritation from
a shoe, but are really the result
of abnormal pressure from a
bone underneath the skin. The
skin reacts from the excessive
pressure of the bone and grows
a protection for itself.
It is uncommon to see corns and
callouses on a child's foot.
When they are present it is
the result of some type of abnormal
foot problem and should be evaluated
and treated.
The areas of the foot where these
lesions are most common are
the outside of the little toe,
on the side of the big toe,
the top of the second toe, and
under the second and fifth bones
in areas on the ball of the
foot.
They may be treated conservatively
with a change to shoes with
more room in the toe area, corn
or callous pads, or trimming.
An orthotic (custom designed
insole) is the best treatment.
It controls the mechanics of
the foot structure that causes
the problem. If the abnormal
pressure is relieved, the symptoms
improve.
Children rarely need surgery for
these conditionss unless all
conservative care has been attempted
and failed, or if the condition
causes pain or problems with
wearing shoes comfortably.
(back to the table of contents)
Conditions
That Affect the Growth Centers
of Bone
A child might develop pain or
begin to limp without any history
of injury. The complaint does
not go away or can even get
worse. There are several disorders
that occur which affect the
growth centers of the bones
in children. The medical term
used is osteochondritis, osteo
means bone, chondro means cartilage
and itis means inflammation.
This group of disorders of the
growth plates occur in very
specific locations, namely the
hip, tibia (lower leg bone),
arch bone, foot, and heel. While
usually not serious, they are
affected by pressure and weight
on the bone and can change how
the bone is ultimately shaped.
Fortunately, these conditions
are all self-limited. That is,
as the child grows and matures,
the condition will go away.
The goal of treatment is to
make the child as comfortable
as possible during the condition,
and to try not to limit their
normal activities unless they
are unable to continue because
of pain.
The disturbance at the growth
center in the hip joint (Legg-Calve'-Perthes'
Disease) is seen between
the ages of 3 and 12 with boys
being affected six times more
frequently than girls. Although
it most commonly affects only
one hip, both sides can be involved.
It presents with a noticeable
limp and pain in the hip which
can extend all the way down
to the knee. Treatment is to
reduce the pressure on the hip
joint. It could take three to
four years for the condition
to resolve.
Pain and swelling just below the
knee is characteristic of Osgood
Schlatter's Disease. Just
as with the hip problem already
described, the adolescent will
have a limp and usually have
problems climbing stairs. It
is most often seen in children
between the ages of 10 and 15.
Treatment is designed to reduce
stress on the knee.
The keystone to the arch bone,
the navicular, often undergoes
a disruption of a growth center
(Kohler's Disease). X-rays
will demonstrate a markedly
flattened or fragmented bone.
This problem occurs most often
between the ages of 5 and 7
and predominately affects boys.
The child will complain of pain
in the arch of the foot and
will often limp. The preferred
treatment is an orthotic (custom
designed insole) to help support
and cushion the area.
Frequently seen in children between
the ages of 12 and 14 years
of age is a disruption of the
growth plate at the head of
the second metatarsal bone in
the ball of the foot (Freiberg's
Disease). The child may
or may not have had an injury
to this area. Symptoms include
pain, tenderness, problems with
wearing shoes, a limp, and difficulty
participating in sports because
it hurts when trying to push
off the ball of the foot. X-rays
confirm an irregular flattened
head of the second metatarsal
bone. The second toes looks
shorter and there is less motion
in the joint. This condition,
although common, rarely needs
to be treated unless there is
pain or restriction of range
of motion that causes constant
problems. The use of injections
and physical therapy normally
does not help. The child may
respond to orthotics or require
surgery to reshape the joint
and improve motion.
The most common disruption of
the growth plate in a child
occurs in the heel area (Calcaneal
Apophysitis or Sever's Disease).
It is most frequently seen in
overweight or active boys between
the ages of 8 and 13. It predominantly
affects only one heel but can
involve both.
The child will complain of a painful
heel on the bottom or back part
of the foot. It feels better
during periods of rest. Treatment
is always conservative utilizing
spongy heel cups or soft orthotics.

Injury Related
Conditions of the Foot and Leg
Fractures and Dislocations
Fractures in children heal at
a more rapid rate than those
in adults. In an adult, a broken
bone can take six to eight weeks
or longer to heal, whereas in
a child it may be several weeks
less. The same is true regarding
the soft tissue structures surrounding
the bone. Whereas an adult may
take three to four weeks to
heal, a child may take one to
two weeks to heal.
The main difference in fractures
in young children versus adults
is that the child has much more
soft cartilage and numerous
growth plates. When a child
sustains an injury not only
might they break a bone, but
they also may injure the cartilage
or growth plate. This can affect
the way the bone will grow.
In fact, about 30% of all injuries
in children also involve a growth
plate.
X-rays of fractures or dislocations
in children frequently reveal
the injury across the growth
plate. They may also have bone
fragments that get pulled away
from the bone because the ligaments
in children are very strong.
Children's bones are much more
pliable and able to bend before
they completely break. They
may have an incomplete fracture
(greenstick) which will heal
more rapidly.
Fractures are almost always associated
with an injury. The area will
be painful and swollen. As with
all injuries, immediately ice
the area, elevate the foot and
leg, and wrap the area in an
elastic bandage. Additionally,
no weight should be applied
to the area. Consult your physician
and have x-rays taken.
Sometimes the bone will break
or crack, but it will not show
up immediately on x-rays. It
should be treated as if it were
broken, and a repeat x-ray taken
several weeks later. If symptoms
persist, a special test called
a bone scan can be ordered by
your doctor. This will detect
a fracture that is invisible
on a standard x-ray.
The most common area for a stress
fracture is the second bone
in the ball of the foot called
a metatarsal bone. It occurs
because there is a weight shift
from the first to the second
metatarsal bone which occurs
with a flattening or inrolling
of the foot structure. This
weight shift causes excessive
pressure on the second bone.
When the amount of pressure
exceeds the bone's ability to
withstand, the bone cracks.
Another common area for a stress
fracture is the sesamoid bones.
These are like small knee caps
and are situated under the head
of the first bone in the ball
of the foot. They function to
give extra power to the muscles
in the arch to pull the big
toe down. Commonly seen in young
teenage girls, it can be quite
disabling. Cross-country running
or any activity where there
is chronic and repetitive stress
on the bone structure can cause
the bone to break. It must not
be confused with a sesamoid
bone that can grow normally
in two pieces although appear
as if it was fractured. X-rays
of both feet, for comparison,
and a bone scan often help make
the correct diagnosis.
Dislocations due to injury can
occur when two bones separate
at the joint. If a dislocation
occurs, the surrounding soft
tissue, such as the ligaments,
also will be stretched and torn.
The dislocation must be reduced
as quickly as possible to restore
proper alignment and function.
It generally will heal satisfactorily
in two to four weeks. Physical
therapy may be required to aid
in restoring the active range
of motion, tone, and strength.

Overuse Injuries
to the Knee (Chondromalacia)
Many times a child will complain
of a painful knee without any
history of injury. In almost
every case it is the result
of an overuse problem caused
by abnormal foot and leg mechanics.
In general, if the problem is
on the inside part of the knee,
it is due to excessive inrolling
or flattening of the foot structure.
If it is on the outside part
of the knee it is related to
a high arched, non-shock absorbing
foot structure (supination).
It can also be due to the presence
of a leg-length difference,
weak thigh muscles or an increase
in the angle formed between
the hip and knee. The condition
is caused by repetitive micro-trauma
as seen in walking or running.
The knee cap (patella) is inside
of a tendon which is attached
to muscles in the thigh. The
tendon inserts or attaches into
the bone just below the knee.
When the foot rolls excessively,
the knee cap is pulled out of
it's groove that it slides up
and down in and irritates the
cartilage. It is commonly felt
as a grating sensation of the
knee cap on the leg bone.
Treatment is directed not only
at the symptoms but at the cause
of the problem. We often use
anti-inflammatories and an orthotic
to help absorb shock and balance
the foot structure. This helps
to prevent twisting of the leg
and prevent the abnormal rubbing
of the knee cap in it's groove.

Shin Splints
T he term shin splints is defined
as any symptom characterized
by pain or discomfort in the
lower leg. More frequently seen
in females than in males, it
is thought to be really a combination
of three conditions: Tendonitis
or an inflammation of the tendon,
myositis or an inflammation
of the muscle itself, and periositis
or an inflammation of the covering
of the bone, termed periostium.
Shin splints can occur on the
lower front part or inside back
part of the leg.
The type that occurs on the front
of the leg is mostly due to
overuse and poor conditioning.
The muscle tendon unit gets
overused, swells, and causes
pain.
The type that occurs on the
inside back of the leg is due
to over pronation or inrolling
of the foot. It usually affects
only one leg, and in those who
have a difference in the length
of their legs.
The treatment for shin splints
is physical therapy, anti-inflammatory
medication, strengthening exercises,
and most importantly an orthotic
to control foot and leg position.
(back to the table of contents)
Achilles Tendonitis
Pain in the back of the lower
leg is almost always associated
with an inflammation of the
Achilles tendon and its covering.
In fact, it is reported to be
the most common problem of the
lower leg.
Associated with overuse or a tight
heel cord, it can become very
painful and swollen. The child
will often not want to walk
and will limp. More than one-half
of the injuries to the Achilles
tendon are from abnormal inrolling
of the foot. Slow motion video
studies have demonstrated a
whipping type motion of the
Achilles tendon that occurs
with inrolling or a flattened
foot structure. This causes
micro-tears in the tendon and
results in inflammation.
Treatment for Achilles Tendonitis
is threefold; stretching of
the calf muscle and tendon,
control of the inflammation
and pain, and control of the
function of the foot structure.
This would include physical
therapy with the use of stretching
exercises and massage, the use
of anti-inflammatory medication,
and orthotics to control foot
motion and to raise the heel
thus decreasing the pressure
of the tendon.

Common Hereditary
and Developmental Bone Problems
Seen in Children
Juvenile Bunions
Often the result of heredity,
juvenile bunions are seen in
children's feet where there
is a strong family history of
the problem. The child typically
exhibits a very flexible foot
structure with a low arch. The
juvenile bunion is really caused
by the flatfoot structure and
a too tight heel cord. Whether
to treat the entire condition
or only the bunion itself is
a matter to be determined by
examination. We will discuss
how to make decisions about
surgery at the end of this section.
Juvenile bunions are usually seen
more often in girls than in
boys between the ages of 10
and 12. They do not commonly
cause pain unless there is excessive
pressure from a shoe. The great
toe shifts towards the second
toe and a large bump develops
at the joint area in the ball
of the foot. This is not an
extra or new bone as we might
see in an adult. The bump we
see is actually the entire first
metatarsal bone in the ball
of the foot having shifted or
moved out of alignment. If it
remains in this abnormal position
the child's condition will progress
and worsen. Unsightly and painful
hammertoes with corns and callouses
on the bottom of their foot
structure will also form.
There are two treatments for juvenile
bunions. First and most importantly,
an orthotic must be used to
control the forces that caused
the bunion in the first place.
Second is to operate on the
juvenile bunion to reposition
and realign the bone. This will
allow the foot to function properly.

Hammertoes
/ Mallet Toes
The little toes of the foot
have three bones and two joints.
The big toe has two bones and
one joint. When a little toe
contracts and humps up between
the first and second bones it
is called a hammertoe. When
the second and third bones contract
up it is termed a mallet toe.
Hammertoes and mallet toes are
caused by an imbalance between
those muscles and tendons on
the top of the foot which pull
the toes up, and those on the
bottom of the foot which pull
the toes down. These problems
are often seen on all the toes
in children with a very high
arched foot structure because
the muscles and tendons pull
the toes up and to the side.
Conversely, a child who has
a flat foot structure will have
contracture of the second and
fifth toes.
Hammertoes and mallet toes begin
gradually. At first there is
mild contracture of the toes
with areas of redness and irritation.
They progressively get worse
and can even get infected as
well as very painful.
The initial treatment of hammertoes
and mallet toes is conservative.
Special toe pads and orthotics
can be used successfully. Conditions
that do not respond to conservative
care can be corrected with surgery.

Medial Pinch
Callous of the Great Toe
The big toe often develops a
hard callous on the side caused
by excessive inrolling of the
foot. The toe begins to angle
towards the second toe. It is
commonly associated with other
foot problems such as juvenile
bunions and hammertoes. Treatment
is to smooth down the callous
on a routine basis and use an
orthotic to help prevent the
inrolling of the foot. Surgery
can also correct the problem.
There are two methods used.
Either the excessive bone is
filed smooth, or a pie-shaped
wedge is removed to correct
the excessive angle of the toe.

Tailor's Bunion
When there is too much pressure
from a shoe on the outside of
the foot, or abnormal foot function,
or both, the child can develop
a tailor's bunion. Tailors used
to sit and sew with their legs
crossed. Due to excessive pressure
on the outside of the foot,
the underlying bone would enlarge
and cause a painful area directly
over the head of the metatarsal
bone. Thus the conditions were
termed tailor's bunion. In a
child whose foot incorrectly
contacts the ground, too much
pressure is put on the outside
part of the foot from the shoes
or foot structure, thus causing
the tailor's bunion to form.
Also, between the bone and the
skin, there is a balloon-like
structure called a bursa. This
helps to absorb shock and tries
to cushion the area. When this
gets inflamed, bursitis develops.
This is why a tailor's bunion
can get red and swollen and
get seemingly enlarged.
Treatment is to help reduce
the pressure on the outside
part of the foot by using appropriate
pads or orthotics. Surgery is
indicated when all attempts
at conservative care have failed.

Accessory
Bones (Extra Bones)
More frequently seen in adolescent
girls than in boys, the accessory
or extra bone, gives the appearance
of a lump or enlargement in
the middle of the arch. Sometimes
called a double ankle, the extra
bone grows inside of the tendon
responsible for lifting the
arch. Studies indicate it occurs
in 15% to 20% of the population.
The extra bone can become painful
and makes shoes uncomfortable
to wear. Conversely, it can
not cause any symptoms whatsoever
until the child accidentally
injures the area. The bone can
then become dislodged or crack
away from its normal position
and cause pain.
Usually no treatment is needed
for this problem unless it becomes
painful or the child has problems
wearing shoes because the bone
hits the inside of the shoe.
Cortisone injections to try
to reduce inflammation should
not be used as this can weaken
the tendon. This is only a temporary
relief and is quite painful
in this sensitive area. When
necessary, surgical removal
of the bone is quite successful
in resolving the problem.

Ganglions
and Cysts
A ganglion is a fluid-filled
sack-like growth that can occur
anywhere on the foot or ankle.
It is usually found along the
course of the tendon. Tendons
pass through a sheath or covering.
There is an oil-like liquid
between the tendon and it's
sheath which lubricates the
tendon and aids in it's sliding
action. An injury or poorly
fitted shoe can cause the tendon
covering to tear, allowing the
fluid inside to leak out. The
body then forms a sack-like
structure to prevent it from
spreading. Besides forming along
tendons, this type of structure
can also form from fluid that
leaks out from between joints.
Ganglions and cysts can get quite
large and feel as hard as a
rock. They can cause pain or
numbness if they cause pressure
on surrounding soft tissues,
especially on blood vessels
and nerves. If small and not
in an area that causes a problem,
they can generally be ignored.
If they grow in a vital area,
enlarge, or cause pain, they
should be surgically removed.
Sometimes injections can help
reduce the size of the ganglion,
but this relief is mostly temporary.
If surgery is performed, the
area where the ganglion was
removed needs to be well protected
until the healing process completely
takes place to avoid re-growth.

Enlargement
on the Back of the Heel (Haglund's
Spur)
Most frequently seen in adolescent
girls, this enlargement on the
back of the heel is caused by
an abnormal foot structure and
pressure from shoes. Originally
called a "pump-bump"
after a particular type of shoe,
it can be quite disabling. Because
of the enlargement on the back
of the heel, the Achilles tendon
gets irritated as does the surrounding
soft tissue structures. The
top back part of the shoe presses
right on this area and makes
it impossible to walk comfortably.
X-rays will show an abnormal
enlargement on the heel bone.
Treatment can be rather simple.
A small heel lift inside of
the shoe will change the position
of the foot in the shoe and
reduce a great deal of the pressure
on the back of the heel. Changing
the style of the shoe can also
be helpful. An orthotic is the
best treatment to control foot
function and lift the heel at
the same time. Surgery is indicated
in cases where there is no relief
from conservative care.

Childhood
Ankle Conditions
Ankle problems in children are
uncommon. The structures around
a child's ankle joint are much
more flexible than those of
an adult and rarely get injured.
There are ligaments on both sides
of the ankle joint. The outside
ligaments are much weaker than
those on the inside. Often,
when an ankle sprain occurs,
conservative care such as rest,
ice, a compression wrap, elevation,
physical therapy, and an ankle
support help to restore normal
function. If the child frequently
injures or sprains their ankle,
or has an ankle that is constantly
weak or unstable, then further
evaluation is needed. A complete
examination will include stress
x-rays. These are special x-ray
views that help determine if
there is any looseness to the
ligaments. The ligaments around
the ankle are like tiny steel
cables that connect the bones
together and prevent instability.
A regular x-ray without appropriate
pressure on the ankle cannot
determine if the bones move
apart when they should not.
Besides the ligaments, there is
a balloon-like structure called
a capsule that surrounds the
ankle joint. It has a lining
that functions to produce lubrication
for the joint to work smoothly.
When the capsule and it's lining
get inflamed, the ankle joint
will swell and become painful.
The cartilage inside of the joint
or the bone itself can get injured.
If there is pain or weakness
and it lasts longer than three
to six weeks, it should be investigated
further.
Most children's ankle joint
problems are not due to the
ankle joint itself being abnormal.
They are usually secondary to
abnormal foot and leg problems
that affect the ankle joint.
If the primary problem is corrected,
the ankle joint discomfort usually
resolves.

Children in
Dance and Sports
We have discussed that a child's
foot structure, both the bones
and soft tissues, are soft and
pliable. They are subject to
undue strains and pressures
during any sports activities.
Are these activities really
bad for the child's foot structure?
Anything done in excess can
cause a problem but, in general,
dance and sports are not bad
for the feet. Injuries can occur
and be treated appropriately.
Accidents can and will happen.
However, there is a big difference
between an injury and chronic,
long term pressure on a growing
moldable foot structure.
For example, ballet is excellent
for its development of coordination,
tone, and strength. Because
of certain required dance positions,
it can be helpful in de-rotation
of the legs such as in pigeon-toed
gait problems. On the other
hand, dancing up on the toes
(pointe) is to be avoided because
it puts undue pressure on the
bones as they grow. Certainly
no child should ever consider
toe dancing until the age of
10 to 12 years, or until the
feet mature. Certain positions
in ballet causes the foot to
flatten or cause toe problems
such as hammertoes and bunions.
The best advice to follow is not
to overdo any sport or activity
in a young child. Excessive
pressure and stress on the growing
structures can lead to overuse
syndromes with resultant foot
and leg fatigue and actual foot
problems. As always, use common
sense and try not to give into
every desire of the child. Remember,
the foot structure during growth
is delicate and needs to be
supported and balanced.

A Word About
Children and Surgery
One of the most difficult decisions
parents can make is whether
or not their child should undergo
surgery. The decision is easier
to make when the child has a
major foot problem. In these
cases, the choice is more clear
and the benefits obvious. However,
in more subtle situations where
the benefit or change would
not be fully appreciated until
the child matures, it is a much
more difficult decision. The
parents will often desire a
second opinion, as well as seek
opinions from family members
and friends. An opinion may
also be sought from a family
of a patient who has already
undergone a surgical procedure
to correct a foot problem. Once
the decision is made to proceed
with the surgery, there is a
measurable amount of emotional
relief. Most of the children
handle the experience much better
than their parents, and quickly
return to the normal childhood
activities. Treating the child
can be harder on the emotions
of the parents than the child.
In almost every case, the child
should first have conservative
care unless there is an obvious
need to proceed with surgery
immediately. After a period
of one or two years, if there
is little improvement with conservative
treatment or normal growth,
surgery should be contemplated.
Remember, most children do not
complain of pain as a symptom.
This is due to the cartilage
and flexible nature of their
structures. They do, however,
subjectively present with being
clumsy, have problems wearing
shoes, or have excessive shoe
wear and an abnormal walk.

Conclusion
The foot is a marvelous structure.
It must function properly to
allow the child to grow to adulthood
and to lead a life of normal,
pain-free walking and activities.
Unfortunately, the foot and
how it functions are frequently
overlooked by many health professionals
and parents. Beware of the statement,
"Don't worry, your child
will outgrow it".
This book provides the information
needed to appreciate and understand
most foot and leg problems your
child could have. Do not take
an ostrich approach. Do not
stick your head in the sand,
wishing that the problem will
go away. That does not make
it so. A wise man once said
"There are three things
I cannot cope with, pain, disappointment,
and reality!".
Ask questions of your doctor.
If you do not like the answer
you receive, or do not understand,
get another opinion. Do not
forget, your child's feet must
last a lifetime. Many problems
treated early can be resolved
so as to never cause a problem
later. Parents need to know
and understand common foot and
leg problems to help their children
lead a lifetime of good foot
health.
