Surgical procedure at the proximal part of the femoral diaphysis: The skin incision is situated directly above the greater trochanter (Fig. 5a). The incision in the deep layer of the fascia lata reveales the medial gluteal muscle that is separated longitudinally (Fig. 5b) to expose the lateral of the quadriceps muscle (Fig. 5c). The lateral vastus is split longitudinally (Fig. 5d) and the final drill hole is inserted in the centre at the base and 1.5 cm distally to the tip of the greater trochanter (Fig. 5e).
