Clinical aspect of foot

Talipes

Talipes refers to club foot. Any affection of the ankle which may lead to deformity is called club foot. There are four forms of club foot

  • Dorsiflexion club-foot called calcaneus

  • Plantarflexion club-foot called equinus

  • Inversion club-foot called valgus

  • Eversion club-foot called varus

There can be a combination of all the above such that you have 8 combinations with a ninth one that stands on its own called cavus. It is a hollowing of the midpart of foot. All are referred to as talipes.

 

Calcaneus/dorsiflexion

Equinus/plantarflexion

Valgus/eversion

Varus/inversion

Calcaneovalgus/dorsiflexion-eversion

Calcaneovarus/ dorsiflexion-inversion

Equinovalgus/plantarflexion-eversion

Equinovarus/iplantarflexion-inversion

Cavus/in hollowing

 

 

 

 

 

 

By far the commonest club-foot is talipes equinovarus.

Hammer toe

The extensor apparatus in the foot has similar architecture with the hand. The major difference is that the interossei do not enter the extensor expansion on the metatarsophalangeal joints. Hence the ability to keep the writing position is weak except in some individuals who have learnt to use the foot in such position. When the lateral plantar nerve is damaged, the extensor mechanism is further weakened just as the damage to ulnar nerve weakens in the hand. The foot is now placed in a reverse writing position with the interphalageal joints flexed and the metatarsophalangeal joint extended. This leads to hammer toe and it affects the 2nd toe more frequently than other toes.
