Muscle Anatomy

gluteus medius

The gluteus medius muscle is positioned in the lateral aspect of the hip and is relatively smaller than the neighboring gluteus maximus. It contributes to the contours of the hip and plays a crucial role in hip joint dynamics.

Originating from the external surface of the ilium, specifically between the posterior and anterior gluteal lines, the gluteus medius takes its starting point from the bony prominence of the pelvic girdle.

The muscle inserts into the lateral surface of the greater trochanter of the femur. This insertion point allows the gluteus medius to exert its influence on the hip joint and the proximal part of the femur.

Functionally, the gluteus medius is a key abductor of the hip joint. It plays a vital role in moving the leg away from the midline of the body, contributing to activities like walking, running, and maintaining stability during standing. Additionally, the muscle aids in pelvic stabilization during the stance phase of gait, preventing unwanted tilting. The gluteus medius is instrumental in maintaining balance and controlling the alignment of the lower limb, showcasing its significance in overall hip and lower limb function.
