| Gluteus Medius | |
|---|---|
| Muscle Type | |
| Origin | Gluteal surface of ilium, under gluteus Maximus. Three areas of origin: gluteal fossa, gluteal aponeurosis, and posterior inferior edge of the lip of the iliac crest. |
| Insertion | Greater trochanter of the femur. Three points of insertion: tendinous portion of the aponeurosis inserts onto the superolateral facet, the remainder inserts along an anteroinferior oblique line on the lateral facet. |
| Action | Abduction of the hip; preventing adduction of the hip. Medial/internal rotation and flexion of the hip (anterior fibers). Extension and Lateral/external rotation of the hip (posterior fibers) |
| Synergists | Gluteus Minimus, Tensor Fascia Lata, Gluteus Maximus |
| Antagonists | Hip Adductors |
| Spinal innervation | L4, L5, S1 |
| Peripheral Innervation | Superior Gluteal Nerve |
| Vasculature | superior gluteal artery |
