Gluteus minimus
Gluteus minimus
The Gluteus minimus (pronounced: /ɡluːˈtiːəs ˈmɪnɪməs/), or the smallest of the three gluteal muscles, is situated immediately beneath the Gluteus medius.
Etymology
The term "Gluteus minimus" is derived from the Latin words 'glutaeus' meaning 'buttock' and 'minimus' meaning 'smallest'.
Anatomy
The Gluteus minimus originates from the external surface of the iliac bone, and converges to a tendon that attaches to the anterior border of the greater trochanter of the femur. It functions together with the Gluteus medius and Gluteus maximus to provide rotation and stabilization of the hip joint.
Function
The primary function of the Gluteus minimus is to abduct the hip, moving the leg away from the midline of the body. It also helps in medial rotation of the thigh. When the hip is flexed, the Gluteus minimus works with the Gluteus medius to internally rotate the hip.
Clinical significance
Injury or strain to the Gluteus minimus can result in pain and limited mobility. This is often seen in athletes who engage in running or jumping sports. Physical therapy, including exercises to strengthen the Gluteus minimus, can often help to alleviate symptoms.
