There is surprisingly little consensus on the anatomy of the lateral hip rotators[1]
Muscle | Origin | Insertion | Innervation |
---|---|---|---|
Piriformis | Anterior surface of sacrum between and laterally to the anterior sacral foramina | Superior boundary of greater trochanter | Nerve to the piriformis (S1-S2) |
Gemellus Superior | Ischial spine | Upper edge of Obturator internus muscle tendon (indirectly greater trochanter) | Nerve to obturator internus (L5-S2) |
Internal Obturator | Medial surface of obturator membrane and the surrounding bone | Medial surface of greater trochanter | Nerve to obturator internus (L5-S2) |
Gemellus Inferior | Just above the tuberosity of the ischium | Lower edge of Obturator internus muscle tendon (indirectly greater trochanter) | Nerve to quadratus femoris (L4-S1) |
Quadratus Femoris | Lateral edge of the tuberosity of the ischium | Intertrochanteric crest | Nerve to quadratus femoris (L4-S1) |
External Obturator | Lateral surface of obturator membrane and the ischiopubic ramus | Trochanteric fossa | Posterior branch of obturator nerve (L3-L4) |
