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.
Horse care
The legs of a horse require routine observation for lacerations or swelling. Everyday care involves brushing the legs with a brush to remove dirt and mud. A currycomb is generally not used below the knees. It is common to have excess hair trimmed from the fetlock to prevent excess accumulation of mud and moisture that may lead to skin problems, such as rain rot or scratches. Many riders wrap the horse's legs with protective boots or bandages to prevent injury while working or exercising. After a ride, it is common for a rider or groom to hose off the legs of a horse to remove dirt and to ease any minor inflammation to the tendons and ligaments. Liniment may also be applied as a preventative measure to minimize stiffness and ease any minor strain or swelling. If the horse has been overworked, injured, or is to be transported, a standing bandage or shipping boot may be placed on the horse's legs for protection, to hold a wound dressing, or to provide support. Leg wraps are useful in preventing injury or for treating horses with leg injuries. Veterinarians may recommend using wraps during rehabilitation to prevent further injury. Another common use for leg wraps is to protect the legs of horses while being shipped in a horse trailer.
