• Intrauterine enteroviral infection • Hyperlaxity
• Development arrest
PATHOLOGY

• Shortened • Medial rotation
• Head - Medial deviation • Equinus
• Body External rotate. Extruded • Adduction

CASTING TECHNIQUE
• Before each cast is applied, the foot is manipulated

• Never ever touch the heel
ONE HAND TECHNIQUE
TWO HANDS TECHNIQUE
PONSETI TECHNIQUE
• Start soon after birth

• All deformities are corrected spontaneously except equinus
• Cavus is corrected by elevating the first metatarsal
• The entire foot is abducted under the talus
SEQUENCE OF MANIPULATION
(PONSETI TECHNIQUE)
unwished du
1. Corrected cavus deformity (1st-2nd wk)
• Elevate/Supination first metatarsal + Head of talus -> fulcrum
2. Corrected forefoot adductus and hindfoot varus (2nd-6th/8th wk)
Serial cast • Forefoot Abduction
• Hindfoot Evert/external rotate around the talus, while maintain
supination of forefoot
• Head of talus : fulcrum
• Avoid pronation,dorsiflexion a c a

3. Corrected equinus deformity (7th/9th wk)

• Achilles tenotomy

• 10-20 degrees dorsiflexion
• Final LLC 3 weeks

Tenotomy
• For corrected equinus

• Indication
– Talar head is covered
– Heel is in slight valgus
– Foot is maximally abducted 60 – 70˚
– < 15 degrees dorsiflexion
Tenotomy
• Position
• 1 cm above Achilles tendon
insertion
• Incision
• Insert blade medial side of heel
and parallel to tendon
• Turned the blade ˚ and resect

• Nighttime

Keep ext.rotation 70 , dorsifle 15 in clubfoot and 40-45 in normal foot

Biggest risk factor of recurrent deformity : Noncompliance
PITFALL IN MANIPULATION
• Pronation of foot
• Increase cavus and locking
calcaneus under talus
IN pronate w :
• Correct adduction by external rotation of the foot while

calcaneus is in varus
• Posterior displacement of lateral malleolus
• Correct equinus before other deformities
• Rocker bottom deformity
-
• Forceful dorsiflexion
• Flat-top talus
• Abducting the foot at the midtarsal joints with the thumb pressing
on the lateral side of the foot near the calcaneocuboid joint
• Abduction of the calcaneus is blocked -> interfering with correction of
the heel varus
OPERATIVE TREATMENT
• Indication
• Failed non-operative treatment
• Controversy in timing of surgery
• Different techniques
• Turco, Mckay, Simons, Corroll
• Goal
• Restore or create, as normal a foot as possible
• 3P : Painless, Pliable, Plantigrade
OPERATIVE TREATMENT
• Deformities that do not respond to conservative treatment by

serial manipulation and casting.
• Posteromedial release (PMR)
• Dynamic supination
• TA transfer to 3rd cuneiform
