[Diabetic foot]

Diabetics suffer from a high rate of amputation. Unclear terminology is partially responsible. We offer a clear classification (type A = PAOD; type B = polyneuropathy; type C = combination of A + B). Our classification for plantar ulcer is simple and yields clear indications for appropriate therapy. The operative principles for type B, foot will be discussed (dorsal incision, distal two-thirds resection of metatarsals, proper coverage of bones with soft tissues, necrectomy, placement of Gentamycin-bonded collagen sponge, drainage, primary wound closure, plantar ulcer left untouched). In a collection of 284 treated type B diabetic feet, in only 6% of cases was there secondary wound healing. The plantar ulcer was always cured.
