Gemellus+superior


 * Author: Mishka Kadir**

toc =Description = Gemellus superior is an elongated muscle, of triangular shape. This muscle is located in the gluteal region across the anterior wall of the pelvic bone. It originates from the gluteal surface of the spine of the ischium. The fibres of this muscle run laterally, combine with the tendon of the obturator internus, and insert at the medial surface of the greater trochanter of the femur. Gemellus superior is responsible for lateral rotation of the hip, abduction of the flexed thigh and stabilisation of the the hip joint. This small muscle receives innervation from the nerve to the internal obturator, L5, S1 and S2. Its vascular supply comes from the inferior gluteal artery and internal pudendal artery.

=Interactions and relations to other Muscles = Gemellus superior is one of the external rotators of the hip, these are also otherwise known as the six deep lateral rotator hip muscles. The lateral rotator muscles are synergists of the gemellus superior. These muscles are namely, (in order of their position relative to each other) piriformis, gemellus superior, obturator internus, gemellus inferior, obturator externus and quadratus femoris. Gemellus superior, specifically, lies between piriformis and obturator internus. Gemellus superior, gemellus inferior and obturator internus join to form the conjoined tendon. The gemellus superior is antagonised by the gluteus medius and minimus when performing lateral rotation. =Relevance to Occupational Therapy = Occupational Therapists are also involved in physical exercise during treatment. OTs know how to perform range of motion evaluations. To evaluate gemellus superior and its surrounding muscles, the client sits on the testing surface, with hips at 90 degree flexion and the knees flexed at the edge of the testing surface (refer to [|figure 3-6-31]). The client then moves the hip in exteral rotation to assess the range of motion.
