The Borden and Gearen modification of the Sugioka transtrochanteric rotational osteotomy in avascular necrosis. A preliminary report.
Since 1985, ten transtrochanteric rotational osteotomies have been performed following the modification of Borden and Gearen for osteonecrosis of the femoral head. All patients were evaluated functionally and roentgenographically. There were five Ficat Stage II and five Ficat Stage III lesions. The involvement of femoral head necrosis averaged 33%. Good results were obtained in seven patients after an average of 28 months from the surgical procedure. The Borden and Gearen modification requires calibrated guide wires inserted under an image intensifier to obtain precise rotation and rigid internal fixation of the femoral head. This procedure is technically easier to perform than the original Sugioka osteotomy and gives similar results.
