Lateral Hip Rotator	Origin	Insertion
External Obturator	External surface of obturator membrane; rim of pubis and ischium bordering obturator foramen	Trochanteric fossa on medial surface of greater trochanter
Gemelli Muscles	Superior Gemellus: Spine of ischium Inferior Gemellus: Upper border of ischial tuberosity	Superior Gemellus: Upper edge of Obturator internus muscle tendon (indirectly greater trochanter) Inferior Gemellus: Lower edge of Obturator internus muscle tendon (indirectly greater trochanter)
Internal Obturator	Internal surface of obturator membrane and edges of obturator foramen (ischium and pubis)	Medial aspect of greater trochanter (trochanteric fossa)
Piriformis	2, 3, 4 costotransverse bars of anterior sacrum, few fibers from superior border of greater sciatic notch	Anterior part of medial aspect of greater trochanter of femur
Quadratus Femoris	ateral border of ischial tuberosity (just below inferior gemellus)	Quadrate tubercle on intertrochanteric crest of femur
