Theadductor brevis is a muscle in the thigh situated immediatelydeep to thepectineus andadductor longus. It belongs to theadductor muscle group. The main function of the adductor brevis is to pull the thighmedially.[1] The adductor brevis and the rest of the adductor muscle group is also used to stabilize left to right movements of thetrunk, when standing on both feet, or to balance when standing on a moving surface. The adductor muscle group is used pressing thethighs together to ride a horse, and kicking with the inside of the foot in soccer or swimming. Last, they contribute toflexion of the thigh when running or against resistance (squats, jumping, etc.).[2]
It is somewhat triangular in form, and arises by a narrow origin from the outer surfaces of the body of the pubis andinferior ramus of thepubis, between thegracilis andobturator externus.
The Adductor brevis muscle widens in triangular fashion to be inserted into the upper part of the linea aspera immediately lateral to the insertion of pectineus and above that of adductor longus.
By its anterior surface, the adductor brevis is in relation with thepectineus,adductor longus, and anterior branches of theobturator artery, theobturator vein, and theobturator nerve.
By its posterior surface with theadductor magnus and the posterior branches of theobturator artery, the obturator vein, and the obturator nerve.
By its outer border with theobturator externus, and theiliopsoas. By its inner border with thegracilis and adductor magnus.
It is pierced near its insertion by the middleperforating artery.[3]
The adductor brevis is innervated dually by the anterior and posterior branches of the obturator nerve.[4]
The muscle is primarily known as ahip adductor. It also functions as ahip flexor. Whether it acts to rotate the femur laterally or medially is dependent on position.
