Management of Osteomyelitis and Bone Loss in the Diabetic Charcot Foot and Ankle

Abstract

Bone loss and destruction due to diabetic Charcot neuroarthropathy (CN) and osteomyelitis of the foot and ankle is a challenging clinical condition when lower extremity preservation is considered. Resection and excision of osteomyelitis and associated nonviable soft tissue can lead into large osseous and soft tissue defects that will most likely need the utilization of bone grafting and subsequent arthrodesis for stability and anatomic alignment. In the diabetic population with peripheral neuropathy, osseous instability can lead to subsequent lower extremity deformity, ulceration, infection and/or amputation. This article reviews the surgical approach in the presence of diabetic CN and concomitant osteomyelitis.
