Successful treatment of nonunion with teriparatide after failed ankle arthrodesis for Charcot arthropathy

We describe a case of successful treatment to nonunion after multiple arthrodesis operations for Charcot arthropathy with teriparatide. We describe the case of a 25-year-old woman with severe Type I diabetes mellitus that resulted in nonunion after multiple arthrodesis operations for Charcot arthropathy. The woman sustained a femoral shaft fracture for which she underwent surgery with intramedullary nail fixation. Immediately after surgery, an empiric course of teriparatide was initiated. Femoral shaft fracture healing was observed after 2 weeks, and the woman was able to walk 12 weeks after the surgery, at which point plain film and computed tomography images revealed complete union of the ankle.
