Adductor Magnus Innervation !new! | 2024 |

The adductor magnus is anatomically divided into two distinct portions: the adductor part (or pubofemoral portion) and the hamstring part (or ischiocondylar portion). The adductor part originates from the inferior pubic ramus and the ramus of the ischium, inserting along the gluteal tuberosity and the linea aspera of the femur. This portion is primarily responsible for adducting and medially rotating the thigh. Because of its location and function, it is innervated by the posterior division of the obturator nerve, which carries fibers from the L2, L3, and L4 spinal nerve roots.

Understanding the specific innervation of the adductor magnus is vital for clinical assessment, particularly in the context of nerve injuries and compartment syndromes. adductor magnus innervation
