The gluteus medius is a muscle of the gluteal region in the lower limb. It is a fan-shaped muscle which lies between the gluteus maximus and minimus.
- Attachments: Originates from the gluteal surface of the ilium and inserts onto the lateral surface of the greater trochanter.
- Actions: Abduction and medial rotation of the lower limb. It stabilises the pelvis during locomotion, preventing ‘dropping’ of the pelvis on the contralateral side.
- Innervation: Superior gluteal nerve.
- Blood Supply: Superior gluteal artery.
