Which muscle provides adduction and medial rotation of the hip without hip flexion?

• A. Adductor Magnus
• B. Adductor Longus
• C. Gluteus Medius
• D. Tensor Fasciae Latae

Answer: (A)

Adductor Magnus is capable of adducting the thigh and medially rotating it while not requiring hip flexion. Its adductor portion pulls the thigh toward the midline and assists with medial rotation, and its hamstring portion crosses the hip posteriorly to extend the hip. So you can achieve adduction and medial rotation without flexing the hip. Other muscles listed are more associated with abduction or flexion: gluteus medius mainly abducts (with medial rotation when the hip is flexed), and tensor fasciae latae flexes and abducts rather than adducting. Adductor longus also adducts but is more a hip flexor, not as clearly aligned with the without-flexion condition.
