Exploration of gluteal region and hip
Gluteus medius and piriformis muscles; sciatic nerve, left posterolateral view
The aponeurosis covering the anterior part of the gluteus medius has been reflected anteriorly. The gluteus maximus has been cut off close to its origins to demonstrate the underlying bony landmarks and ligaments in relation to the remaining muscles.
