A heel foot ( Latin Pes calcaneus) is a malposition of the foot in which the foot bends upwards (dorsiflexion or extension ) and the sole of the foot rotates outwards ( pronation ), so that the patient can only walk on the heel. The misalignment is congenital or acquired through poliomyelitis (polio) or trauma .
root cause
The so-called hook foot is caused by an injury or contusion of the tibial nerve ( nervus tibialis ). This nerve supplies, among other things, the calf muscle, triceps surae , which normally lowers the foot and turns it inward. When the nerve fails, the muscle is no longer active and the foot can only be partially lowered to the ground ( plantar flexion ). This failure of the tibial nerve can also affect the deep flexor box on the lower leg.
treatment
Conservative therapy consists of redressement (manual and technical correction and overcorrection with subsequent fixation ); an alternative is surgery .
