The gluteus minimus is one of the secondary muscles that can produce hip extension. This muscle is located deep and somewhat anterior to the gluteus medius. The gluteus medius is a broad and triangular muscle. It is a strong abductor that serves as a medial rotator of the thigh at the hip joint. The gluteus minimus and gluteus medius are separated by deep branches of the superior gluteal neurovascular bundle. The gluteus minimus emerges from the external surface of the ilium, between the base and the front of the gluteal lines. It inserts into the greater trochanter of the femur. Along with the gluteus medius and tensor fasciae latae, the gluteus minimus serves as the primary internal rotator of the hip joint. The gluteus minimus helps to abduct and medially rotate the thigh at the hip. Together with the gluteus medius, it steadies the pelvis when the opposite leg is raised from the ground. Meanwhile, the tensor fasciae latae helps to internally rotate the hip joint.
