Adductor brevis is one of the medial thigh muscles. It arises from the body and inferior ramus of the pubis. It inserts into the pectineal line and the superior third of the linea aspera of the femur.
Its main action is to adduct the thigh at the hip. Also, it is a weak flexor of the extended hip.
It is innervated by the anterior division of the obturator nerve (L2-L4).
