ATTACHMENTS:

• The gluteus minimus attaches from the external ilium to the greater trochanter of the femur.

ACTIONS:

• The entire gluteus minimus abducts the thigh at the hip joint and depresses the same-side pelvic bone at the hip joint.
• The anterior fibers also flex and medially rotate the thigh and anteriorly tilt and ipsilaterally rotate the pelvis at the hip joint.
• The posterior fibers also extend and laterally rotate the thigh and posteriorly tilt and contralaterally rotate the pelvis at the hip joint.

NOTES:

• The gluteus medius and gluteus minimus have essentially the same attachments and therefore essentially the same joint actions.
• The major difference between the gluteus medius and minimus is that the anterior fibers of the deeper gluteus minimus are oriented more horizontally in the transverse (horizontal) plane, therefore these fibers are more active with medial (internal) rotation of the thigh at the hip joint than the anterior fibers of the gluteus medius.
• The gluteus minimus is located deep to the gluteus medius.
