Anatomy[edit | edit source]
The gluteus medius is one of three gluteal muscles (minimus, medius and maximus). It is a superficial, fan shaped and broad muscle that lies in the posterolateral aspect of the pelvis, inferior to the iliac crest.[1] The gluteus medius has a broad origin on the external (gluteal) ilium and its tendon inserts into the lateral aspect of the greater trochanter.[2] The muscle is overlapped by the gluteus maximus and covered with a strong layer of fascia.[1]
Origin: External (gluteal) surface of ilium between anterior and posterior gluteal lines.[1] Reaches from iliac crest superiorly and as far as the sciatic notch inferiorly.[1] Superficial to gluteus maximus.[2]
Insertion: Lateral surface of greater trochanter.[2] A bursa seperates the tendon from the greater trochanter.[3]
Nerve: The Superior Gluteal Nerve (SGN) supplies the gluteus medius. The SGN originates at the sacral plexus at levels L4, L5 & S1.[4] The SGN divides into several branches, supplying both the gluteus medius and minimus as it passes horizontally between them both, prior to terminating at the tensor facsia latae.[4]
Blood Supply: Superior gluteal artery and superior gluteal vein.[2]
