In a retrospective review, seventeen patients injured in Vietnam who sustained both a lower-extremity amputation and a fractured femur are reported. After an initial period of skeletal traction, early ambulation in a modified cast-brace and pylon was initiated for each patient. Average time to clinical union was twenty-two weeks. At the time of discharge, 50 per cent of the patients had an arc of motion in the involved knee of 75 degrees or more. No increased angulation occurred in the cast-brace when properly used. Shortening was not significant. Rehabilitation of these severely injured patients was felt to be improved and shortened with the described techniques.
