Exposure of buttock
Posteriror hip exposure




Place patient in mid-lateral position. Start your skin incision on the upper 5 cm of the femur until it reaches the tip of greater trochanter. Then turn the incision posteriorly over the buttock towards the posterior superior iliac spine to reach about 9cm.

Divide the fascia lata over the upper end of femur. Incise the fibrous layer on the gluteus maximus. Separate the horizontal fibers of gluteus maximus to expose the gluteal pad of fat and the sciatic nerve. Open the gluteal bursa.

Incise the floor of gluteal bursa immediately posterior to the greater trochanter

Divide the short lateral rotators muscles (piriformis, obturator internus, obturator externus, quadratus femoris) to expose the hip joint.
