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.
Children's feet
Contemporary management of the paediatric flat foot is directed according to pain, age, and flexibility, considering gender, weight, and joint hypermobility. When foot orthoses are indicated, inexpensive generic appliances will usually suffice. The paediatric flat foot proforma (p-FFP) directs this evidence-based approach. Three randomized controlled trials (RCTs) and one quasi-RCT have investigated the use of foot orthoses in children. The Cochrane Library systematic review analyzing the studies could not make a single recommendation, concluding that customised foot orthoses should be reserved for children with foot pain and arthritis, for unusual morphology, or unresponsive cases. There is an identified need for further research in this area. Surgery is rarely indicated for paediatric flat foot (unless rigid) and only at the failure of thorough conservative management.
