Origin | Gluteal surface of ilium, under gluteus medius. |
|---|
Insertion | Greater trochanter of the femur |
|---|
Action(s) | The gluteus medius and gluteus minimus abduct the thigh, when the limb is extended, and are principally called into action in supporting the body on one limb, in conjunction with the Tensor fasciæ latæ. Their anterior fibers, by drawing the greater trochanter forward, rotate the thigh inward, in which action they are also assisted by the Tensor fasciæ latæ. |
|---|
Nerve Supply | superior gluteal nerve (L4, L5, S1 nerve roots) |

Arterial Supply | Superior gluteal artery |

Discussion | Variations: The muscle may be divided into an anterior and a posterior part, or it may send slips to the piriformis, the superior gemellus or the outer part of the origin of the vastus lateralis. Relations: A bursa is interposed between the tendon and the greater trochanter. Between the gluteus medius and gluteus minimus are the deep branches of the superior gluteal vessels and the superior gluteal nerve. The deep surface of the gluteus minimus is in relation with the reflected tendon of the rectus femoris and the capsule of the hip joint. |
