Last revised by Henry Knipe on 4 Nov 2024

The gluteus medius muscle is one of the hip abductors and one of three muscles that make the superficial gluteal muscles.

Summary
  • origin: gluteal surface of the ilium between the posterior and anterior gluteal line, gluteal aponeurosis, and posteroinferior iliac crest 1-3

  • insertion

    • anterior fibers insert into the gluteus minimus tendon 5

    • posterior and lateral fibers insert respectively onto the superoposterior and lateral facets of the greater trochanter of the femur 5

  • arterial supplysuperior gluteal artery

  • innervationsuperior gluteal nerve

  • action

    • abducts the femur at the hip joint

    • holds pelvis secure over stance leg and prevents pelvic drop on the opposite swing side during walking

    • medially rotates thigh

  • bursa: separating the upper part of the lateral surface of the greater trochanter from the tendon 

  • antagonist: adductors
