o The true etiology of congenital clubfoot is
unknown
oExtrinsic associations include oExtrinsic associations include � Teratogenic agents (eg, sodium aminopterin)
� Oligohydramnios
� Congenital constriction rings
Maria Carmela L. Domocmat, RN, MSN 8
oGenetic associations include
o mendelian inheritance (eg, diastrophic dwarfism;
o autosomal recessive pattern of clubfoot inheritance).o autosomal recessive pattern of clubfoot inheritance).
o Cytogenetic abnormalities (eg, congenital talipes
equinovarus [CTEV]) can be seen in syndromes
involving chromosomal deletion.
Maria Carmela L. Domocmat, RN, MSN 9
oTalipes may be positional or structural. � Positional talipes is caused by abnormal pressures
compressing the foot while it's developing, as a result
of its position in the womb.
� Structural talipes is a more complex condition and
probably caused by a combination of factors, such as
a genetic predisposition

o deformity is readily apparent at birth
o can be detected antenatally during the routine
development ultrasound scan around 20 weeks.development ultrasound scan around 20 weeks.
o X-rays may be needed to confirm diagnosis.
Maria Carmela L. Domocmat, RN, MSN 11
o treatment is most successful when started
early in infancy because delay causes muscles
and bones of legs to develop abnormally, and bones of legs to develop abnormally,
with shortening of tendons

intervals

� involves serial manipulation and plaster casting of the clubfoot.
� The ligaments and tendons of the foot are gently stretched with weekly, gently manipulations. stretched with weekly, gently manipulations.
� A plaster cast is then applied after each weekly sessions to retain the degree of correction obtained and to soften the ligaments. Thereby, the displaced bones are gradually brought into the correct alignment.
� Four to five long leg (from the toes to the hip) are applied with the knee at a right angle.

� extended medical supervision is required
� bcoz there is a tendency for this deformity to recur

normal shoes and walk properly)normal shoes and walk properly)
� care emphasizes muscle reeducation (by
manipulation) and proper walking

• Approximately 50-60% of club feet in newborns
can be corrected non-operatively.
• About 20% of infants requiring surgery need • About 20% of infants requiring surgery need
further surgery at a later stage.

• imperfect development of hip –can affect
femoral head, acetabulum, or both
• head of femur does not lie deep enough within • head of femur does not lie deep enough within
the acetabulum and slips out on movement
• occurs in females 7 times more often than males

o acetabular dysplasia� mildest form
� femoral head remains in acetabulum
o subluxation o subluxation � most common form
� femoral head partially displaced
o dislocation � femoral head not in contact with acetabulum
� displaced posteriorly and superiorly
Maria Carmela L. Domocmat, RN, MSN 27
o limitation in abduction of leg on affected
side
o asymmetry of gluteal, popliteal, and thigh o asymmetry of gluteal, popliteal, and thigh
folds
o Waddling gait and lordosis when child
begins to walk

� With child in a supine position, the right knee on the side of the subluxation the subluxation appears lower than the left because of malposition of the femur head.

� Doctor abducts the hips by moving the bent
hips and knees apart.
If the hip feels like it can be pushed out the � If the hip feels like it can be pushed out the
back of the socket, this is considered
abnormal.
� This is called a positive Barlow's Test and is a
sign of instability in the hip.
Maria Carmela L. Domocmat, RN, MSN 31
� As the hip is abducted further, the doctor
might feel the ball portion (the femoral head)
slide forward as it slips back into the socket.

� femur is cut and rotated to make it easier to
keep the femoral head inside the acetabulum.
� When this procedure is done, the soft tissues
loosen up and the forces of the muscles tend to loosen up and the forces of the muscles tend to
keep the femoral head reduced.
� Once again, the child is put in a spica cast for
several months while the bone heals.
� A CT scan may be used to confirm successful
reduction before removing the cast.

� Several different types of osteotomies are used to
tilt the acetabulum in a more horizontal angle to the
floor. By doing this, the femoral head is less likely to
slide up and out of the socket with weightbearing. slide up and out of the socket with weightbearing.
� Types : Steele osteotomy; Salter osteotomy;
Pemberton osteotomy
Maria Carmela L. Domocmat, RN, MSN 50
� This can stop the femoral head from sliding
up and out of the socket.
� Over time this shelf of bone above the
acetabulum remodels and forms a deeper acetabulum remodels and forms a deeper
acetabulum.
� the bone of the pelvis just above the
acetabulum is cut to allow the bone to slide
out and form a new roof over the hip joint.
Maria Carmela L. Domocmat, RN, MSN 51
Maria Carmela L. Domocmat, RN, MSN 52
� uses a bone graft placed just above the hip
joint to create a new, wider roof, or shelf over
the acetabulum.
This keeps the femoral head from sliding up � This keeps the femoral head from sliding up
and out of the socket and, as it heals, makes a
larger weightbearing surface to spread out
the weight that needs to be transferred from
the femoral head to the acetabulum and
pelvis.
Maria Carmela L. Domocmat, RN, MSN 53
Maria Carmela L. Domocmat, RN, MSN 54
� not as common
� the entire acetabulum is cut free of the pelvis
and moved or dialed at the best angle and
then allowed to heal in that position.then allowed to heal in that position.

o Same with other clients with cast and
braces; pre- and post-op care
o Transportation and positioningo Transportation and positioning� use wagon or stroller with back flat or mechanic’s
creeper
� protect child from falling when positioned
� never pick up child by the bar between the legs of
cast (use two people to provide adequate body
support if necessary)
