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
5. Forcible correction of the equinus (and cavus) by dorsiflexion against a tight Achilles tendon results in a spurious correction through a break in the midfoot, resulting in a rocker-bottom foot. The cavus should be separately treated as outlined in step 2, and the equinus should be corrected without causing a midfoot break. It generally takes up to 4–7 casts to achieve maximum foot abduction. The casts are changed weekly. The foot abduction (correction) can be considered adequate when the thigh-foot axis is 60°. After maximal foot abduction is obtained, most cases require a percutaneous Achilles tenotomy. This is performed in the cast room under aseptic conditions. The local area is anesthetized with a combination of a topical lignocaine preparation (e.g. EMLA cream) and minimal local infiltration of lidocaine. The tenotomy is performed through a stab incision with a round tip (#6400) Beaver blade. The wound is closed with a single absorbable suture or with adhesive strips.The final cast is applied with the foot in maximum dorsiflexion, and the foot is held in the cast for 2–3 weeks.
