VASTUS-PSOAS RELEASE FOR ACETABULAR EXPOSURE IN REVISION HIP-SURGERY

A technique is presented for wide exposure of the acetabulum for revis ion total hip arthroplasty surgery in the presence of a solidly fixed, modular, or monoblock femoral component without the need for trochant eric osteotomy. The technique involves release of the proximal portion of the vastus lateralis, vastus inter-medius, and vastus medialis mus cles and the iliopsoas tendon from the femur and placement of the femo ral head/neck posterior to the acetabulum. The exposure afforded by th is release usually precludes the need for trochanteric osteotomy: and/ or removal of a well-fixed femoral component in revision surgery that is being done for isolated loosening of acetabular components, thereby decreasing operative time, morbidity, and the risks of complication o f trochanteric osteotomy.
