Description[edit | edit source]
Gemellus superior is a small muscle in the posterio-latereal portion of the hip. It works with gemellus inferior and obturator internus, to form the triceps coxae, to externally rotate the hip[1]. These three muscles also act as the deep stabilisers of the hip.[2]
Origin[edit | edit source]
Gemellus superior originates from the outer (gluteal) surface of the spine of the ischium[3]
Insertion[edit | edit source]
It has a blended insertion with the upper part of the tendon of the Obturator internus.[3]
Nerve[edit | edit source]
Nerve to obturator internus, which is formed from portions of the L5, S1, and S2 spinal nerves.
Artery[edit | edit source]
Inferior gluteal and internal pudendal arteries
Function[edit | edit source]
The gemelli muscles act to externally (laterally) rotate the hip.
Clinical relevance[edit | edit source]
Together with its twin: gemellus inferior as well as obturator internus and piriformis, gemellus superior is a deep stabiliser of the hip joint. These four muscles work with gluteus maximus to resist anterior forces of the hip. [5]
It is difficult to assess gemellus superior in isolation due to its proximity to the other external rotators of the hip. Testing of the external rotators would be done in a normal hip assessment.
