The gluteus medius (Latin: musculus gluteus medius) is a broad fan-shaped muscle located between the gluteus maximus and gluteus minimus muscles. Together with the tensor fasciae latae, all gluteal muscles (including the gluteus medius) are classified as the muscles of the gluteal region. The gluteus medius stretches between the ilium of the hip bone and femur.
|Origin||Gluteal surface of ilium between anterior and posterior gluteal lines|
|Insertion||Greater trochanter of femur|
|Action||Thigh abduction, thigh internal rotation (anterior fibers), thigh external rotation (posterior fibers), pelvis stabilization|
|Innervation||Superior gluteal nerve (L4 - S1)|
|Blood supply||Superior gluteal artery|
The gluteus medius muscle originates from the gluteal surface of the ilium between the anterior and posterior gluteal lines.
Along with the gluteus minimus, the gluteus medius inserts on the greater trochanter of the femur.
Primarily the gluteus medius is an abductor, and it provides abduction of the thigh at the hip joint. Contractions of the anterior fibers of the muscle result in internal rotation of the thigh, while contractions of the posterior fibers result in external rotation of the thigh during knee extension. Also, the gluteus medius stabilizes the pelvis.
