Gluteus Medius

Written by Oliver Jones

Last updated October 19, 2022 • 2 Revisions •

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.
