13. CLUB FOOT
Definitions
it is a congenital dysplasia of all musculoskeletal tissues
distal to knee in the form of deformity of the foot and
ankle joint complex characterized by forfoot
adduction,heel varus ,and ankle equines with or
without tibial internal torsion
Talipes: Talus = ankle
Pes = foot
Equinus: (Latin = horse)
Foot that is in a position of
planter flexion at the ankle,
looks like that of the horse.
Calcaneus: Full dorsiflexion at the ankle
14. CLUB FOOT
Planus: flatfoot
Cavus: highly arched foot
Varus: heel going towards
the midline
Valgus: heel going away
from the midline
Adduction: forefoot going
towards the midline
Abduction: forefoot going away
From the midline
Forefoot Hind foot
17. HISTORY
•Hippocrates first described the clubfoot deformity around 300B.C.
•Scarpa – 1803 – “congenital dislocation of the astragalo calcaneo scaphoid complex”
(twisting of scaphoid os calcis and cuboid around the astragalus)
• Lorenz – 1782- subcutaneous tenotomy of the Achilles tendon
• Adams – 1866 - differentiated acquired talipes equinovarus from the congenital variety
• Guerin – 1838- first to report PoP in treatment of clubfoot
• Phelps – 1890- one stage medial plantar soft tissue release with lengthening of the
tendons
• HICAM KITE – 1930- popularized nonoperative treatment with serial manipulation and
cast immobilization
Idiopathic (Unknown
Etiology) :
Congenital Talipes Equino-
Varus
18. Commonest congenital orthopaedic abnormality
1 to 2 in 1000 live births (0.6 per 1000 in Asian population)
Much more common in Polynesian & Maori & lower in Asians
Males: Females :: 2.5:1.0
DOMINANT INHERITANCE WITH REDUCED PENETRATION / MULTIFACTORIAL
Bilaterality – 50%
right side slightly more affected then left (almost equal)
Bilateral deformity more resistant then unilateral
EPIDEMIOLOGY
19. Etio-pathogenesis
Still Unknown at this stage
SOME ETIOLOGICAL THEORIES ARE :
Mechanical factors in utero
Retractive fibrotic response
Neuromuscular defect
Arrested embryonic development
Primary germ plasma defect
Heredity
Environmental factors
Combined heredity and environmental factors
Vascular hypothesis
20. Neuromuscular defect
• Imbalance between type I and type II muscle fibres and atrophy of type I fibres seen both in
peroneal and triceps surae histologically
CPN PALSY- weak peroneal muscles
weak pronators and overacting of invertors
• not all with spina bifida have clubfoot
• deformities associated with congenital neurologic defects don’t have same constant
characteristics of idiopathic clubfoot
• neurological deformed foot are flexible
• such clubfoot can be placed in dorsiflexion
• Plantar flexed talus and talipes calcaneovalgus are more common than TEV, in neurological
problems
Retractive fibrotic response;
• Zimny et al identified myofibroblastic retractile tissues in medial
ligaments
• Ponseti et al identified increase in collagen fibres in ligaments and
tendons
•Decreased density of nerve fibres in synovium of clubfeet. This lack of
sensory input responsible for fibrosis and contractures.
BUT, Clubfeet are associated with syndromes of inherent ligamentous
laxity
21. .Arrested embryonic development
• Heuter and Volkmann ; BOHM
• 6 – 8 week fetus has foot with many characteristics of congenital clubfoot, which
become normal by 12 -14 weeks
• Victoria Diaz et al –
Fibula Phase – calcaneus pushed and displaced into equinovarus
tibial phase – talus pushed and feet pronated
tibial growth spurt
• BUT, dysmorphic talar head and medial dislocation of navicular are never
• observed in fetal development
.Primary germ plasma defect in cartilaginous talar anlagen produces dysmorphic talar
neck and navicular subluxation which are not found in normal embryonic
development
Primary germ plasm defect in the talus: continued plantar flexion and
inversion of this bone, with subsequent soft-tissue changes in the joints and
musculotendinous complexes
22. Hypoplasia or absence of the anterior tibial artery in majority of CTEV
patients**

25. Adaptive Changes
Wolff’s Law
“ Every change in the use of static function of bone causes a
change in the internal form or architecture as well as
alteration in its external formation and function according to
mechanical law ”
26. PATHOLOGICAL ANATOMY
COMPONENTS OF DEFORMITY :
1. EQUINUS – fixed plantar flexed foot
Ankle joint
inversion of talocalcaneonavicular joint
plantar flexion of forefoot
2. VARUS – inward rotation of hindfoot
talocalcaneonavicular joint (subtalar joint)
calcaneus rotate through talocalcaneal joint
in coronal and horizontal plane
3. ADDUCTION –
Talonavicular joint
anterior subtalar joint
Lisfranc region
4. CAVUS – prominent transverse plantar crease
midtarsal joint
pronation of the forefoot in
relation to the hindfoot.
27. OSSEOUS DEFORMITIES
TALUS :
Body – EXTERNALLY ROTATED (Herzenberg et al)
- broader anterior portion of trochlea with flaring of facet articulating with fibula
Neck – short ; decreased neck-body axis from normal 150 – 160 deg. To around 90-115
- internally rotated relative to ankle mortise
Head – medially deviated ; talonavicular articulation in sagittal plane than normal
coronal plane
Inferior surface – anterior and middle facets of subtalar joint are noncongrant, shallow and
lessdeveloped
28. Calcaneus
involved in equenus varus
adduction due to abnormal
position but shape is almost
maintained
Anterior portion lies beneath the
head of talus causing varus and
equinus of heel
Anteriar end come downward
andRotated medially while posterior
end moves upward and lateraly
29. NAVICULAR - medial and plantar displacement on head of talus
- hypertrophy of medial tuberosity due to thick ligamentous structures
tethering navicular to medial malleolus and calcaneus
- false articulation with medial malleolus in sever e defomity
The navicular tuberosity is close
to the medial malleolus
34. • FLEXOR DIGITORUM ACCESSORIUS LONGUS – 7% of children requiring surgical correction
-Children having first degree affected relatives are 7 times more likely to have this
muscle than those without such pedigree
• Deficient dorsalis pedis flow in 45% of clubfeet compared to 8% of controls
(J Pediatr Orthop 2003)
• Deficient posterior tibial artery also documented in severe clubfeet
• ISCHEMIC NECROSIS of foot

orientation of bone
• During infancy – helpful in assessing the correction.
• more accurate objective record for assesssment of correction
•surgical planning
• intraoperative assessment of correction
45. Classification
Cummin classified CTEV as
Supple: foot can be brought to normal position ,
alljoints are mobile
Relapsed: deformities are corrected initially but
appears again in later years partially or totally
Recurrent : type of relapse , the cause being muscle
imbalance which was overlooked initially
46. Rigid : it’s a type in which forefoot deformity is corrected
but the hindfoot deformities remain uncorrected after
conservative treatment
Neglected : patient has not received any treatment
for one year.
Resistant: it’s a type of clubfoot where there is no
correction after conservative treatment
Atypical clubfoot: short, chubby, stiff feet with a deep crease
in the sole of the foot and behind the ankle, and shortening
first metatarsal with hyperextension of the MTP joint.

63. The principles of treatment are based on following concepts :
1. Abnormal tarsal relationship maintained by pathological after soft tissues contractures
2. Soft tissues contractures must be stretched to restore normal tarsal relationships
3. After normal tarsal relationships, correction must be maintained until tarsal bones
remold stable articular surfaces
4. Recurrent deformity results from failure to either attain a complete correction or
maintain the correction
64. Ponseti management
According to ponseti Scientific Basis
of Management
Clubfoot is not an embryonic
malformation. A normally
developing foot turns into a clubfoot
during the second trimester of
pregnancy. Clubfoot is rarely
detected with ultrasonography before
the 16th week of gestation. Therefore,
like developmental hip dysplasia and
idiopathic scoliosis, clubfoot is a
developmental deformation
The forefoot is in some pronation,
causing the plantar arch to be more
concave (cavus).
The clubfoot deformity occurs mostly
in the tarsus.
65. No single axis of motion (like a mitered hinge) exists
on which to rotate the tarsus,whether in a normal or a
clubfoot. The tarsal joints are functionally
interdependent. The movement of each tarsal bone
involves simultaneous shifts in the adjacent bones
correction of the extreme medial displacement and
inversion of the tarsal bones in the clubfoot
necessitates a simultaneous gradual lateral shift of the
navicular, cuboid, and calcaneus before they can be
everted into a neutral position
Pronating the clubfoot on this imaginary fixed axis
tilts the forefoot into further pronation, thereby
increasing the cavus and pressing the adducted
calcaneus against the talus. The result is a breach in
the hindfoot, leaving the heel varus uncorrected
66. the anterior portion of the
calcaneus lies beneath the head of
the talus. This position causes
varus and equinus deformity of the
heel. Attempts to push the
calcaneus into eversion without
abducting it will press the
calcaneus against the talus and will
not correct the heel varus. Lateral
displacement (abduction) of the
calcaneus to its normal
relationship with the talus will
correct the heel varus deformity of
the clubfoot.
The bones and joints remodel with
each cast change because of the
inherent properties of young
connective tissue, cartilage, and
bone, which respond to the
changes in the direction of
mechanical stimuli.
67. Current ponseti management
The Ponseti technique corrects the
deformity by graduallyrotating the
foot around the head of the talus
(red circle) over a period of weeks
during cast correction.
When possible, start soon after birth
(7 to 10 days). However, most
clubfoot deformities can be
corrected throughout childhood
using this management
Most clubfoot deformities can be
corrected in approximately 6 weeks
by weekly manipulations followed
by plaster cast applications. If the
deformity is not corrected after six
or seven plaster cast changes, the
treatment is most likely faulty.
68. Surgery Vs casting : Surgery improves the initial
appearance of the foot but does not prevent
recurrence. Adult foot and ankle surgeons report that
these surgically treated feet become weak, stiff, and
often painful in adult life.
Ponseti management is appropriate for use in children
with arthrogryposis, myelomeningocele, Larsen
syndrome and other syndromes. Treatment is more
difficult as correction takes longer and special care
must be given in infants with sensory problems as in
myelodysplasia to prevent skin ulcers.
69. Ponseti cast application
first step calming the child with a
bottle or breast feeding. When
possible have a trained assistant
Exactly locate the head of the
talus
you can feel the prominent lateral
part of the talar head barely covered
by the skin in front of the lateral
malleolus
While moving the forefoot laterally
in supination, you will be able to feel
the navicular move ever so slightly in
front of the head of the talus as the
calcaneus moves laterally under the
talar head.
70. All components of clubfoot deformity,
except for the ankle equinus, are
corrected simultaneously. To gain this
correction, head of the talus, which is
the fulcrum for correction
reduce the cavus first :The cavus,
which is the high medial arch is due to
the pronation of the forefoot in
relation to the hindfoot, The forefoot
is supinated to the extent that visual
inspection of the plantar surface of the
foot reveals a normal appearing arch—
neither too high nor too flat,
Alignment of the forefoot with the
hindfoot to produce a normal arch is
necessary for effective abduction of the
foot to correct the adductus and varus.
71. CORRECTION OF ADDUCTION AND HEEL VARUS
The whole foot abducted under the talus
Thumb on head of the talus, not the calcaneus.
The navicular moves away from the medial malleolus
The foot should never be everted
manipulation and casting are continous for next 2-3 weeks to abduct the foot
gradually
76. EQUINUS CORRECTION;
The equinus deformity gradually improves with correction of adduction and
varus.
This is part of the correction because the calcaneus dorsiflexes as it abducts
under the talus.
No direct attempt at equinus correction is made until the heel varus is
corrected Final cast applied in maximally abduction and dorsiflexion,
in most children percutaneous tenotomy is done to prevent rochker bottam
foot deformity
Residual equinus- manipulation and casting +/- percutaneous tenotomy
Make certain that abduction is adequate for performing the tenotomy.
77. Casts and foot Adequate abduction
Best sign of sufficient
abduction: ability to
palpate the anterior
process of the calcaneus as
it abducts out from
beneath talus
Abduction of approx.70
degrees in relationship to
the frontal plane of the
tibia possible
78. Percutaneous tenotomy under LA
Foot held in max dorsiflexion by an assistant
Tenotomy done 1.5 cm above calcaneal insertion
Additional 25-30 deg dorsiflexion obtained
Cast with the foot abducted 60 to 70 degrees with respect to the
frontal plane of the ankle, and 15 degrees dorsiflexion for 3 weeks
Indicated to correct equinus when cavus, adductus, and varus fully
corrected but ankle dorsiflexion remains less than 10 degrees above neutral
79. Precaution
Notify your doctor or the clinic nurse if you notice
any of the following
• Any foul-smelling odor or drainage coming from
inside the cast.
• Red, sore, or irritated skin at the edges of the cast.
• Poor circulation in the toes (see #1 above).
• Cast slipping off.
• Child running a fever of 38.5°C/101.3°F or higher
without an explainable reason, such as a cold or virus

and incase of U/L cases 30 to
40° of ER in normal side,
distance between shoes set at
about 1˝ wider than width of
shoulders
Knees left free, so the child
can kick them “straight” to

85. • knee-ankle-foot braces, such as the Wheaton brace, maintain the foot
abducted and externally rotated.
• However, the knee-ankle-foot braces keep the knee bent in 90 degrees of
flexion. This position causes the gastrocnemius muscle and Achilles tendon
to atrophy and shorten, leading to relapse of the equinus deformity.
• This is particularly a problem if a knee-ankle-foot brace is used during the
initial 3 months of bracing, when the braces are worn full time.

94. Reasons for relapses
noncompliance of the bracing program.
If relapse occurs in infants who are braced, the cause is an underlying muscle
imbalance of the foot that can lead to stiffness and relapse.
Early relapses
loss of foot abduction and/or of dorsiflexion correction with recurrence of
adductus and cavus.
95. Equinus relapse
The tibia seems to grow faster then the gastrosoleus tendon unit. The muscle is
atrophic and the tendon appears long and fibrotic.
If 10 degree dorsiflexion is not achieved in 4–5 casts in children under 4 years of age
repeat the percutaneous heel-cord tenotomy. Once the equinus is corrected,
resume the nighttime bracing program.
Varus relapse
more common than equinus relapses.

Cincinnati incision. provides
excellent exposure of the subtalar
joint and is useful in patients with a
severe internal rotational deformity of
the calcaneus.
One potential problem with this
incision is tension on the suture line
when attempting to place the foot in
dorsiflexion to apply the
postoperative cast.
To avoid this, the foot can be placed
in plantar flexion in the immediate
postoperative cast and then in
dorsiflexion to the corrected position
at the first cast change when the
wound has healed at 2 weeks. This cast
change frequently requires sedation or

• FHL transferred to peroneus longus (>2yr)
115. COMPLETE SUBTALAR RELEASE (SIMMONS)
Differences with McKay procedure :
1. release of interosseous ligament
2. incision of sheath of FHL and FDL
3. retaining sheath of Tibialis Posterior
4. plane of incision for Z-plasty of tendoachilles
wedge calcaneocuboid osteotomy
116. “
. incomplete subtalar release does not allow the surgeon to correct the
calcaneal rotation beneath the talus. The normalization of the
talonavicular and calcaneocuboid joints requires a complete release of
these joints. Otherwise, the forefoot adduction will persist.”

reduction in the management of clubfoot. J.B.J.S., 1983; 65-B,
1-7)
117. Residual deformities
Residual hindfoot equinus : Achilles tendon
lengthening and posterior capsulotomy of ankle and
subtalar joints
Dynamic metatarsus adductus : Transfer of anterior
tibial tendon, either as split transfer or entire tendon
119. Neglected clubfoot
No / incomplete initial treatment till the age of 1 years
Moderately flexible, moderately stiff, and rigid
Modified Ponseti*: manipulation for 5-10 mins, two weekly
cast change, correction of foot to 30-40° abduction, and
AFO for 1 year
Extensive soft tissue release upto 4 yrs

120. Bony procedures
Dwyer osteotomy
Osteotomy of calcaneus
Opening wedge medial
osteotomy to increase the
length and height of
calcaneus
For isolated heel varus
Modified method uses
lateral incisions
121.
122. Litchblau procedure
Medial soft tissue release
Lateral closing wedge
osteotomy of calcaneus
Prevents long term
stiffness of hindfoot
Shortens the lateral
column
123. DILWYN – EVANS PROCEDURE
• 4 – 8 years
• medial incision
lengthening of tibialis posterior
lengthening of tendoachilles
• lateral incision
Wedge resection of clcaneocuboid joint
calcaneocuboid fusion
DISADVANTAGES
• Valgus deformity
• Restriction of subtalar and tarsal motion
124. Salvage procedures
Triple arthrodesis
Salvage procedure for pain after previous surgical
correction.
Correction of large degrees of deformity in neglected
clubfeet.
Not performed before advanced skeletal maturity, at
age 10 to 12
Lateral closing wedge osteotomy through subtalar and
midtarsal joints
128. TALECTOMY
• severe, untreated clubfoot
•for previously treated clubfoot
uncorrectable by any other surgical
procedures
• neuromuscular clubfoot
129. TENDON TRANSFERS
• peronei are weak
• correction of foot achieved late
• laxity in peronei
relapse
Transfer is indicated if the child is more than 30 months of age the
ossific nucleus of the cuneiform is large enough to ensure the tendon
can heal to the cuneiform and not damage the growth plate and
has a second relapse. Indications include persistent heel varus and
forefoot supination during walking; the sole shows thickening of
the lateral plantar skin.
1. Tibialis Anterior – to base of 3rd or 4th metatarsal (if tibialis posterior is
cut)
- to base of 5th metatarsal (if tibialis posterior is
preserved)
2. Split Tibialis Anterior Transfer
3. Tibialis posterior

134. EXTERNAL FIXATORS
INDICATIONS :
1. > 3 years, adolescents adults
2. relapsed, resistant or neglected clubfeet
3. arthrogryphotic foot
4. children treated with extensive open surgery
5. scarred or infected skin from previous surgery
135. ADVANTAGES :
can be done when conventional surgery is contraindicated :
inadequate, scarred skin
infected foot
very short foot
anesthetic clubfoot d/t myelomeningocele
foot due to polio/ cerebral palsy
simultaneous correction of other deformities
softens the contractures/ tethers
less stiffness
136. PRINCIPLES :
1. DISTRACTION HISTOGENESIS - below 8 years
2. WOLFF’S LAW
3. DIFFERENTIAL DISTRACTION on both sides to prevent articular
damage on convex side
(Convex side distraction is half the rate of concave side)
137. Ilizarov
Correction slow enough
to protect soft tissue
Correction at the focus
of deformity
Simultaneous three-
dimensional, multilevel
correction
Deformity correction
without shortening the
foot
138. CONTROLLED DIFFERENTIAL FRACTIONAL DISTRACTION USING
JESS
2 to 4 transfixing wires in prox tibia Metatarsal Transfixing wire
through
MTs
2 transfixing and 1 axial wire through calcaneum
139. JESS
Fractional, differential distraction used to Sequentially
correct deformities (Medial- 0.25 mm every 6 hours
,Lateral- 0.25 mm every 12 hours)
Distraction continued until approximately 20 degrees of
dorsiflexion and overcorrection of the forefoot deformities
was achieved
Maintained in this overcorrected position for twice as long
as the distraction phase by casts/braces
140. Results with JESS
Good or excellent results reported by Joshi in 84% of
his patients
Recommended in all who have not responded to serial
plaster casting methods.
Similar good results have been reported by other
authors**

141. Complications of surgery
Neurovascular injury
Loss of foot (10% have atrophic dorsalis pedis artery bundle)
Skin dehiscence
Wound infection
AVN talus
Dislocation of the navicular
Flattening and breaking of the talar head
Undercorrection/ Overcorrection (esp with Cincinatti)
Forefoot adductus
Hindfoot varus
Severe scarring
Stiff joints
Weakness of the plantar flexors of the ankle
