Total hip arthroplasty combined with double-chevron subtrochanteric osteotomy

摘要

Subtrochanteric femoral shortening and corrective osteotomy are regarded as an integral part of total hip arthroplasty for a completely dislocated hip or severe deformity of the proximal femur. Alternative femoral osteotomy techniques—transverse, oblique, step-cut, and V-shaped, have been described.
