Posterior hip muscles

There is surprisingly little consensus on the anatomy of the lateral hip rotators^[1]

Components

Lateral Hip Rotator	Origin	Insertion
External Obturator	Outer obturator membrane , rim of pubis and ischium bordering it	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	Inner surface of obturator membrane and rim of pubis and ischium bordering membrane	Middle part of medial aspect of greater trochanter of femur
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	Lateral edge of the tuberosity of the ischium	Intertrochanteric crest
