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.
Nail prick
Veterinary treatment includes taking the shoe off, cutting the hoof clean and opening the nail hole to allow drainage. If the horse is in pain anesthesia of the nerve is given. The hole is irrigated and the hole can be packed with iodine-soaked cotton. Superficial infections may only need one treatment. The horse can be given an antiseptic foot bandage for 3–4 days and then be shod if the lameness is gone. The prognosis is usually good provided that minimal damage occurs to vatial structures of the foot. Tetanus prophylaxis is used for unvaccinated horses.
