Gluteus minimus muscle
Gluteus minimus muscle (shown in red). Posterior view.
The gluteus minimus and nearby small gluteal muscles (posterior view)
|Latin||musculus glutaeus minimus|
|From area in between the anterior gluteal line and inferior gluteal line of Gluteal surface ilium, under gluteus medius.|
|Greater trochanter of the femur|
|superior gluteal artery|
|superior gluteal nerve (L4, L5, S1 nerve roots)|
|Actions||Works in concert with gluteus medius: abduction of the hip; preventing adduction of the hip. Medial rotation of thigh.|
|lateral rotator group|

Origin and insertion
The fibers converge to the deep surface of a radiated aponeurosis, and this ends in a tendon which is inserted into an impression on the anterior border of the greater trochanter, and gives an expansion to the capsule of the hip joint. It is also a local stabilizer for the hip.
The deep surface of the gluteus minimus is in relation with the reflected tendon of the rectus femoris and the capsule of the hip joint.
The gluteus medius and gluteus minimus abduct the thigh, when the limb is extended, and are principally called into action in supporting the body on one limb, in conjunction with the Tensor fasciæ latæ.
Their anterior fibers, by drawing the greater trochanter forward, rotate the thigh inward, in which action they are also assisted by the Tensor fasciæ latæ.
Additionally, with the hip flexed the gluteus medius and minimus externally rotate the thigh. With the hip extended, the gluteus medius and gluteus minimus internally rotate the thigh.[contradictory]
- Paralysis of this muscle or gluteus medius, such as may be caused by the superior gluteal nerve palsy, can lead to difficulty abducting the leg. Patients will compensate for their difficulty walking by adopting a Trendelenburg gait.
