On the right hemipelvis, a longitudinal split of the fascia over the tensor fasciae latae was achieved with artery forceps (A), followed by digital blunt dissection until the anterior inferior iliac spine could be palpated, and then a 2 cm pilot drill hole was made using a three-part drill sleeve (B). A Schanz screw was inserted at the area just above the AIIS and aimed with a medial inclination of 20° (C) and a cephalad inclination of 10–20° (D)
