Gluteus Medius Muscle, Posterior View

Description

Posteriorly, the gluteus medius occupies the lateral ilium just inferior to the iliac crest, with its fan-shaped fibers converging inferolaterally toward the greater trochanter of the femur. Much of the muscle lies deep to the gluteus maximus, but its superior and anterolateral portions can be appreciated where the maximus does not fully cover the iliac wing. Laterally, the iliotibial tract region frames the superficial fascia of the hip, while medially the muscle approaches the sacroiliac area across the posterior iliac crest. Clear relationships. Gluteus medius anatomy matters because it is the primary abductor and a key stabilizer of the pelvis in single-leg stance, the functional basis for the Trendelenburg sign and the compensated Trendelenburg gait seen with superior gluteal nerve palsy or chronic tendon degeneration. This posterior perspective also supports procedural planning: injections placed too medial or inferior in the buttock risk the sciatic nerve, while the upper outer quadrant remains the safer target, in part because of how the medius and maximus partition the gluteal region. For hip surgeons, these fibers define the interval and footprint involved in abductor tendon tears at the greater trochanter. Use this artwork in gross anatomy and kinesiology teaching when you need to explain pelvic stability, hip abduction mechanics, and layered gluteal dissection from a posterior approach, and in orthopedic or sports medicine publications discussing greater trochanteric pain syndrome and abductor repair. It also fits patient-education materials on safe intramuscular injection sites in the buttock and on postoperative precautions after lateral hip procedures.
