Use of plaster casts in the management of diabetic neuropathic foot ulcers.

Neuropathic foot ulceration is a major medical and economic problem among diabetic patients, and the traditional treatment involves bed rest with complete freedom from weight-bearing. We have investigated the use of walking plaster casts in the management of seven diabetic patients with long-standing, chronic plantar ulcers. Although all ulcers healed in a median time of 6 wk, this therapy was not without side effects, which are described in detail. We conclude that casting is a useful therapy for neuropathic ulcers, although several clinic visits, including cast removal and foot inspection, are necessary to avoid potential side effects caused by the casting of insensitive feet.
