Charcot's neuroarthropathy can have devastating consequences if left untreated or misdiagnosed. With progression of the disease from the acute to the chronic phase, substantial deformity and instability may result, leading to ulceration and a nonfunctional limb. The purpose of this case report is to present a staged reconstruction for active Charcot's neuroarthropathy involving the subtalar joint with complete dislocation that resulted in limb salvage and maintenance of limb function at 1-year follow-up. Although for many patients the mainstay of treatment for early Charcot's neuroarthropathy is conservative care with off-loading, early surgical correction that includes external fixation followed by definitive arthrodesis for select patients may be warranted.
Surgical management of hallux rigidus using a polyvinyl alcohol synthetic cartilage implant has gained popularity among foot and ankle surgeons. Although uncommon, appropriate diagnosis and management of a periprosthetic implant infection is critical in limiting morbidity. We present a case report and staged technique for converting a first metatarsal synthetic cartilage hemiarthroplasty to arthrodesis in the setting of a periprosthetic joint infection.
