Trench foot
The mainstay of treatment, like the treatment of gangrene, is surgical debridement, and often includes amputation. Self-treatment consists of changing socks two or three times a day and usage of plenty of talcum powder. Wherever possible, shoes and socks should be taken off, feet bathed for five minutes, patted dry, talcum powder applied and feet elevated to let air get to them.
Ponseti method
1. The calcaneal internal rotation (adduction) and plantar flexion is the key deformity. The foot is adducted and plantar-flexed at the subtalar joint, and the goal is to abduct the foot and dorsiflex it. In order to achieve correction of the clubfoot, the calcaneus should be allowed to rotate freely under the talus bone, which also is free to rotate in the ankle mortise. The correction takes place through the normal arc of the subtalar joint. This is achieved by placing the index finger of the operator on the medial malleolus to stabilize the leg and levering on the thumb placed on the lateral aspect head of the talus while abducting the forefoot in supination. Forcible attempts at correcting the heel varus by abducting the forefoot while applying counter pressure at the calcaneocuboid joint prevents the calcaneus from abducting and therefore everting.
