Subtalar and talonavicular joint dislocation as a presentation of diabetic neuropathic arthropathy with salvage by triple arthrodesis.

Abstract

Ligamentous laxity is a common component of diabetic neuropathic osteoarthropathy. In some cases soft tissue instability leads to spontaneous dislocations or subluxations without any bone destruction. This leads to marked instability in gait and chronic ulcerations. A case report is presented in which talonavicular and subtalar joint dislocation occurred with Charcot osteoarthropathy. The conservative and surgical management including salvage by triple arthrodesis is discussed with follow-up care.
