Fractures in lower limbs with prior amputation. A study of ninety cases.

Eighty-five lower-limb amputees with ninety subsequent fractures of the residual limb were studied retrospectively. Most of the fractures were managed by non-operative methods, with the exception of unstable intertrochanteric fractures and displaced fractures of the femoral neck. Indications for operative and non-operative treatment in below-the-knee and above-the-knee amputees are outlined. No indication was found for reamputation through the fracture site. Before fracture, all amputees used a prosthesis. After healing of the fracture, 97 per cent of the patients with amputation below the knee and 82 per cent of those with amputation above the knee resumed use of a prosthesis.
