Find the centre of the iliac crest (directly above the greater trochanter of the femur) and palpate inferiorly two fingers breadth to find the bulk of the muscle.<ref name="Palastanga et al, 2002" /> To isolate in function, stand alternatively on one limb and then the other, feeling the muscle contract as you weight-bear through that limb.<ref name="Palastanga et al, 2002" /> The muscles will contract alternatively during walking, switching on during stance phase to stabilise the pelvis.<br>

Description[edit | edit source]

Gluteus medius is overlapped posteriorly by gluteus maximus.

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]
