Midterm results of transtrochanteric anterior rotational osteotomy combined with shelf acetabuloplasty for osteonecrosis with acetabular dysplasia: a preliminary report

Our results suggest that anterior rotational osteotomy combined with shelf acetabuloplasty may be a surgical option for osteonecrosis of the femoral head with acetabular dysplasia. Further studies with a larger patient population are necessary to clarify appropriate indications and limitations of this combined surgery.
