A double offset broach handle for preparation of the femoral cavity in minimally invasive direct anterior total hip arthroplasty.

A direct anterior approach is in use for minimally invasive total hip arthroplasty. This approach uses an intermuscular and internerval plane between the sartorius, rectus femoris, and tensor fasciae latae. Although preparation of the acetabulum and implantation of the acetabular component is an easy task with the available instruments, preparation of the femoral canal through this single incision is more demanding. Instrumentation of the femur involves careful preparation of the dorsal capsule, positioning of the operated leg, and leverage of the femur. A broach handle with lateral and anterior offset for the direct anterior approach has been developed to reduce the need for leverage of the proximal femur for preparation of the cavity.
