In this procedure, a prosthetic capsule is created using bone screws, washers, and suture material. The bone screws/washers (usually 2) are screwed into the pelvis just above the rim of the acetabulum. A bone tunnel is created in the femoral neck, which is the segment of bone between the femoral head and the femur itself. The suture material is anchored around the screw/washer, threaded through the bone tunnel, and tightened in a figure 8 pattern. An image of prosthetic capsular repair with bone screws and washers in is shown.
