The gluteus medius is a fan-shaped muscle located in the gluteal region of the lower limb. It is situated between the gluteus maximus and minimus, and acts as an important stabilizing muscle. This article will provide an overview of its attachments, actions, innervation, and blood supply.
The gluteus medius is primarily attached to the gluteal surface of the ilium, a bone in the pelvis. It also inserts onto the lateral surface of the greater trochanter.
The primary function of the gluteus medius is to provide abduction and medial rotation of the lower limb. Its presence also helps stabilize the pelvis during locomotion, preventing the pelvis from dropping on the contralateral side.
The gluteus medius is innervated by the superior gluteal nerve.
The superior gluteal artery is the primary source of blood supply for the gluteus medius.
The gluteus maximus and medius have been partially removed in the image of Fig 1, which shows the other superficial muscles located in the gluteal region.
In conclusion, the gluteus medius is a fan-shaped muscle located between the gluteus maximus and minimus. It functions to provide abduction and medial rotation to the lower limb, as well as pelvic stability during locomotion. The superior gluteal nerve and artery provide its innervation and blood supply, respectively. Fig 1 provides an image of the other muscles located in the gluteal region. It is important to note that the gluteus medius has been partially removed in this image.
