Adductor Magnus Innervation Jun 2026

The "double-wired" nature of the adductor magnus has several practical implications: Adductor magnus muscle - Kenhub

The adductor magnus is divided into two primary functional components, each served by a different nerve: 1. The Adductor Portion (Pubofemoral Part)

The is a complex, massive muscle in the medial thigh that is unique for its dual innervation . Often referred to as a "hybrid" or "composite" muscle, it acts as a bridge between the medial (adductor) and posterior (hamstring) compartments of the leg. adductor magnus innervation

This part forms the majority of the muscle's bulk (roughly 70%). Posterior division of the obturator nerve (L2–L4).

This dual supply explains why complete paralysis of adduction requires combined obturator and sciatic nerve lesions, and why hip extension can be partially preserved after obturator nerve injury.

The adductor magnus is anatomically fascinating due to its hybrid nature. Its innervation by allows it to serve as a powerful extensor (like a hamstring) and a primary adductor. For the clinician and anatomist alike, recognizing this dual supply is essential for accurate diagnosis of thigh and hip pathologies. This part forms the majority of the muscle's
