Abstract
Once routinely used, trochanteric osteotomy in total hip arthroplasty now is usually limited to difficult primary and revision cases. Many variations of the osteotomy and many various techniques for the trochanter reattachment have been described. Our specific surgical technique is presented as well as its advantages and drawbacks. Primary total hip arthroplasty procedures requiring the enhanced exposure provided by trochanteric osteotomy is needed in patients with hip ankylosis or fusion, protrusio acetabuli, proximal femoral deformities, developmental dysplasia, or abductor muscle laxity. Trochanteric osteotomy, in revision arthroplasties, facilitates the removal of well-fixed femoral components and enhance acetabular exposure. In all cases trochanteric osteotomy remains useful to preserve the periarticular muscles and restore the geometry of the artificial hip which are the best ways to prevent dislocation.
