Summary
  • origin

  • insertion: gluteal gluteal tuberosity of the femur and and iliotibial tract

  • gross anatomy:

    • thick flat sheet of muscle sloping from the pelvis down across the buttock

    • fan-shaped muscle with a posterior third lying deep to the posterior recess of the ischioanal fossa

  • action

    • powerful extensor of flexed femur at hip joint

    • lateral stabiliser of hip joint

    • lateral stabiliser of the extended knee joint

      • by tightening the iliotibial tract 2

    • lateral rotator of the thigh

    • abduction at the hip (upper fibres)

  • arterial supply:superior and inferior gluteal arteries

  • innervation:inferior gluteal nerve(L5, S1, S2)

  • bursa:

    • ​between the muscle and ischial tuberosity (ischiogluteal bursa)

    • between the muscle and greater trochanter (trochanteric bursa)

    • between the muscle and upper part of the vastus lateralis (gluteofemoral bursa)

  • antagonist

  • variants

    • fusion of gluteus maximus with tensor fascia latae

    • additional slip of muscular attachment to the gluteus maximus from the ischial tuberosity
