The superior gemellus muscle is a muscle of the human body.

The Gemelli are two small muscular fasciculi, accessories to the tendon of the Obturator internus which is received into a groove between them.

The Gemellus superior, the smaller of the two, arises from the outer surface of the spine of the ischium, blends with the upper part of the tendon of the Obturator internus, and is inserted with it into the medial surface of the greater trochanter.

Etymology: Gemellus is the diminutive of "geminus" meaning twin, doubled or duplicated. The superior and inferior Gemellus muscles are paired and perform the same action.

BACKGROUND: The direct anterior approach in THA requires no detachment of muscle insertions. However, damage to the short external rotator muscles may occur when attempting to elevate the femur for exposure. Although the anatomic insertions of these muscles are approximately known, there are no quan
