Management of diabetic neuropathic foot and ankle malunions and nonunions

Abstract

The management of diabetic neuropathic foot and ankle malunions and/or nonunions is often complicated by the presence of broken or loosened hardware, Charcot joints, infection, osteomyelitis, avascular bone necrosis, unstable deformities, bone loss, disuse and pathologic osteopenia, and ulcerations. The author discusses a rational approach to functional limb salvage with various surgical techniques that are aimed at achieving anatomic alignment, long-term osseous stability, and adequate soft tissue coverage. Emphasis is placed on techniques to overcome the inherent challenges that are encountered when surgically managing a diabetic nonunion and/or malunion. Particular attention is directed to the management of deep infection and Charcot neuroarthropathy in the majority of the cases presented.
