Ankle Arthrodiastasis with Circular External Fixation for the Treatment of Posttraumatic Ankle Arthritis.

Ankle arthrodiastasis provides an alternative surgical treatment of the mild to moderate posttraumatic ankle arthritis. Ankle arthrodesis or ankle implant arthroplasty is usually reserved for the end-stage ankle arthritis and after conservative treatment options have been implicated for a long period of time. Ankle joint destructive procedures are often considered for the older and less active population with strict selected surgical criteria and prolonged rehabilitation. In either ankle joint-sparing or ankle destructive procedures, lower extremity deformity correction will need to be addressed before or at the time of index surgery for the overall patient's successful outcome.
