Gluteus medius is a fan shaped muscles on the lateral hip. It overlays the gluteus minimus and is overlapped, in the posterior portion by the gluteus maximus.
It originates from the exterior surface of the ilium between the posterior gluteal line (by the crest) and anterior gluteal lines. The anterior two thirds is covered by and anchored the gluteal aponeurosis of the fascia lata.
It commonly has 3 sections that converge into a single insertion tendon. The posterior border lies anterior to the piriformis and, occasionally, fuses with the piriformis.
It forms a flat tendonous insertion on the superolateral aspect greater trochanter posterior to the tendon(s) of the gluteus minimus. The tendon of the posterior gluteus medius passes under the tendon of the anterior section as they attach to the greater trochanter. Especially on wider, usually female, pelvic structures, the insertion of the two sections pull on the trochanter at nearly right angles from each other.
More commonly reported anomalies include having two distinct sections, fusing with the piriformis and fusing with the gluteus minimus.
Its attachments are better positioned to abduct the hip joint than the gluteus minimus but it is still very involved in medial rotation when the hip is flexed. This abduction shifts the pelvis collaterally when the foot is fixed.
It works with the TFL muscle and the contralateral quadratus lumborum in suspending the opposite hip while the ipsilateral hip is weight-bearing and the contralateral leg swings.
This site is undergoing changes. Starting in early 2020, we began changing the format of the posts to include more extensive self-care, illustrations, therapist notes, anatomy, and protocols. We’d love your feedback. We are adding posts and converting the old posts as quickly as time permits.

*This site is undergoing major changes. We are reformatting and expanding the posts to make it easier to read, more accessible, and
to include more patterns with better self-care. In the meanwhile, there will be inconsistency in formatting, content, and readability until we get the old posts updated. Please excuse our mess.
