ORIGIN

From a broad area on the posterior surface of the ilium, the posterior gluteal line, the rough area of bone superior and inferior to this line, upward to the iliac crest, the aponeurosis of erector spinae, the dorsal surface of the lower part of the sacrum and the side of the coccyx, the sacrotuberous ligament, and the fascia that covers gluteus medius

 

INSERTION

The muscle has both an upper portion and a lower deep portion. The upper part of the muscle, along with the more superficial fibers of the lower part, end in a thick flat tendon that passes lateral to the greater trochanter and attaches to the iliotibial band of the fascia lata. A bursa is usually found between the greater trochanter and the muscle-tendon unit. The deeper fibers of the lower part of the muscle attach to the gluteal tuberosity, a raised portion of the bone between the attachments of vastus lateralis and adductor magnus
