What does the superior gemellus do?
What does the superior gemellus do?
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. These three muscles also act as the deep stabilisers of the hip.
What does the gemellus inferior muscle do?
Inferior gemellus muscle acts on the hip joint, causing two major movements. When the thigh is in an anatomical position, it pulls the greater trochanter of femur posteriorly, around the bone’s longitudinal axis, causing external (lateral) rotation of the thigh.
What is the origin of the superior gemellus muscle?
Origin. The base of the superior gemellus muscle originates from the gluteal surface of the ischial spine, a thin pointed eminence that emerges from the posterior border of the ischium (the sacrospinous ligament is attached to the point of the ischial spine).

What is the medical definition of a Gemellus?
Medical Definition of gemellus. : either of two small muscles of the hip that insert into the tendon of the obturator internus: a. : a superior one originating chiefly from the outer surface of the ischial spine. — called also gemellus superior. b. : an inferior one originating chiefly from the ischial tuberosity.
What causes pain in the gemellus muscle group?
The most common injury involved with the gemellus muscle group is a strain. A muscle strain is a stretching or tearing of the muscle fibers. The most common condition involved with the gemellus is known as gemellus pain syndrome.
