Which muscle adducts the hip and medial rotates it without flexion?

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

Answer: (A)

The action being tested is a muscle that adducts the thigh and also medially rotates it without causing hip flexion. The adductor magnus fits this best because it is the large medial thigh muscle with fibers that pull the thigh toward the midline (adduction) and, when the hip is not flexed, can help rotate the thigh medially. Its anterior part mainly assists with flexion, but the posterior part extends the hip, allowing the muscle to work in a non-flexed position while still contributing to medial rotation and strong adduction. The other options don’t combine these actions in the same way: the gluteus medius is primarily an abductor with some medial rotation; the tensor fasciae latae flexes and medially rotates but doesn’t adduct; and the adductor longus adducts the thigh but is more involved with flexion rather than acting without flexion.
