Club Foot Gross Review – Orthopedic World

Introduction of Club Foot

Club foot is also called talipes equinovarus. It is  a congenital deformity of the leg occurring in 1 or 2 of thousand births. Males are more affected. Male female ratio is 2:1. One third of these cases are bilateral.

CAUSES of club foot:

Actual cause of club foot is still unknown. But the hypotheses are:

  • Genetic
  • Intrauterine compression
  • Arrest of fetal development
  • Bone anomaly
  • Failure of muscle development
  • Mal position of muscle insertion (specially tibialis anterior)
  • Congenital dislocation of navicular or talus
  • Mother’s disease
  • Drugs during pregnancy
  • Nerve lesion
  • Temporary or permanent impairment of circulation

Club Foot


  • Foot is equines, that is , foot is dorsiflexed and looks like horse foot
  • Hill faces medially and posteriorly
  • Forefoot is adducted and supinated and hind foot is in varus position
  • Hill is high and short
  • Talus protrudes at dorsolateral surface of foot
  • Cuff is thin sometimes
  • In normal neonate, foot can be dorsiflexed up to it touches leg , which is impossible in club foot
  • Deep crease lies on medial and posterior aspect
  • Some creases are fibrous band
  • Sometimes club foot is associated with congenital hip dislocation or spina bifida
  • There may be the absence of creases which is called arthrogryposis.

TYPES of club foot:

  1. Non rigid club foot
  2. Rigid club foot
  3. Resistant or very rigid club foot

X RAY of club foot:

X ray offoot in both anterior posterior and lateral view is indicated. Anterior posterior view is taken keeping the foot planter flexed for 30 degree. Then the angle between the 2 lines, one going parallel to lateral margin of calceneum and other going parallel tomedial margin of talus, is measured. Normally this angle ranges between 20-40 degree. This angle is called Kite’s angle. But in club foot this angle severely decreases, even falls to zero.

Lateral view is taken in forced dorsiflexion offoot. Then angle between 2 lines, one going through lower border of calceneum and other going parallel tolong axis of navicular, measured. This angle should be around 42 degree. In club foot it goes below 20 degree.

TREATMENT of club foot:

Conservative treatment of club foot:

At first manipulation and strapping is done as conservative treatment. Parents are taught how to do manipulation so that they can carry out this with strapping still in place. This should be supervised by orthopaedic surgeon or physiotherapist who will alter the strapping when needed.

As far as the manipulation is concerned, equines should not be tried to correct first, it may cause ‘break’ offoot at mid talar region, which is called ‘ROCKER BOTTOM DEFORMITY’. At first, although forefoot is supinated, it should be supinated to align with hindfoot which is more supinated. When alignment is done, then supination is corrected. Then equines is corrected, which is aided by percutaneous Achillis tendon lengthening.

Resistance cases will declare themselves within 8-12 weeks. Then surgeon will choose operation or continuing conservative treatment.

Operative treatment club foot:

lenghtening of achillis tendon

In club foot operation, various types of incisions can be made. A transverse incision at heel which is continued anteriorly both at medially and laterally (cincinatti incision) or an incision at posterolateral aspect offoot and a separate incision medially (carol incision) can be made.

Posterior aspect ofcapsule of subtalar and ankle joint is released. Cancenofibular ligament is cut which is the key structure for club foot. Tendon of flexor digitorum and flexor hallusis longus needs attention. Achillis tendon is cut in Z shape for lengthening. Superficial part ofdeltoid ligament should be released keeping the deep part to keep ankle stability.

Interosseus ligaments should not be cut, otherwise it may cause overcorrection. Forcorrection of forefoot origin of intrinsic muscle and planter fascia is released.

over correction of club foot

K wire is seldom given in subtalar and talonavicular joint. K wire and cast is kept for 6-8 weeks which is followed by ‘hobble boot’ or custom ankle foot orthosis. Exercise is recommended until active dorsiflexon or skeletal maturity is obtained.

RELAPSED CASE of club foot:

Relapsed club foot is associated with scarring of previous surgery. To treat relapsed club foot triple arthrodesis may be needed. Calcetocuboid fusion or sometimes ccuboid enucleation(Dilwyn Evans) is done. Calcaneul osteotomies may be done in the form of lateral closing wedges or lateral translation. Split of tibialis anterior is transferred to dorsum ofbase of 4th metatarsal and tibialis posterior is transferred to dorsum through interosseus ligaments. But tendon transfer is indicated only if the joints offoot are mobile. Sometimes Illizarov apparatus is used but this is painful.
