Description[edit | edit source]
Gluteus medius is located on lateral aspect of the upper buttock, below the iliac crest. The superior muscle is broad with the muscle narrowing towards its insertional tendon giving it a fan-shape. Posteriorly, the muscle is overlapped by the gluteus maximus. Gluteus medius is an important muscle in walking, running and single leg weight-bearing.[1] Weakness in this muscle has been associated with lower-limb musculoskeletal pathology[2] and gait disturbance following stroke.[3]
Anatomy[edit | edit source]
Origin[edit | edit source]
Gluteal, or lateral surface of the ilium between the posterior and anterior gluteal lines. This is a large area, reaching from the iliac crest above to the almost the sciatic notch below.[1]
Insertion
[edit | edit source]
Posterior fibres pass forwards and downwards, the middle fibres downwards, anterior fibres pass backwards and downwards. Fibres combine to form a flatterned tendon which attaches to the superlateral side of the greater trochanter of the femur.[1]
Nerve supply[edit | edit source]
The gluteus medius is supplied by the superior gluteal nerve (root L4, 5 and S1). Cutaneous supply is mainly provided by L1 and 2.[1]
Function[edit | edit source]
Maintaining single-leg stance is required during walking and running. The opposite li
