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

Components

Lateral Hip RotatorOriginInsertionInnervation
External ObturatorOuter obturator membrane , rim of pubis and ischium bordering itTrochanteric 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 ObturatorInner surface of obturator membrane and rim of pubis and ischium bordering membraneMiddle part of medial aspect of greater trochanter of femur
Piriformis2, 3, 4 costotransverse bars of anterior sacrum, few fibers from superior border of greater sciatic notchAnterior part of medial aspect of greater trochanter of femur
Quadratus FemorisLateral edge of the tuberosity of the ischiumIntertrochanteric crest
