Located on the thigh’s medial side, the hip adductor is a wide, trilateral muscle. There are two primary portions arising of this adductor; the pubofemoral portion, and the ischiocondylar portion. The former arises from the ischiopubic ramus and has short fibres that run horizontally, terminating in the femur, while the latter arises from the ischium’s tuberosity and has fibres that then slope downward at multiple angles, where they insert into the linea aspera and also into its medial prolongation underneath.
When the legs are pulled together from a positon where they are spread-out, the adductor magnus is particularly active, powerfully adducting the thigh and extending the hip joint. When the leg is flexed and rotated to the exterior, the area at the medial epicondyle functions like a medial rotator. Control for the hip adductor comes from two different nerves; the obturator nerve and the tibial nerve.
