Structure
It is somewhat triangular in form, and arises by a narrow origin from the outer surfaces of the body of the pubis and inferior ramus of the pubis, between the gracilis and obturator 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.
Relations
By its anterior surface, the adductor brevis is in relation with the pectineus, adductor longus, and anterior branches of the obturator artery, the obturator vein, and the obturator nerve.
By its posterior surface with the adductor magnus and the posterior branches of the obturator artery, the obturator vein, and the obturator nerve.
By its outer border with the obturator externus, and the iliopsoas. By its inner border with the gracilis and adductor magnus.
It is pierced near its insertion by the middle perforating artery.
Innervation
The adductor brevis is innervated dually by the anterior and posterior branches of the obturator nerve.
