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.
Trench foot
Trench foot was first documented by Napoleon's army in 1812. It became prevalent during the retreat from Russia and was first described by French army surgeon Dominique Jean Larrey. It was also a problem for soldiers engaged in trench warfare during the winters of World War I (hence the name).
