Adductor Brevis Muscle Anatomy Overview
The adductor brevis, the short adductor, lies deep to the pectineus and adductor longus, it’s one of the medial compartment of the thigh. Where it arises from the body and inferior ramus of the pubis, it widens as it passes distally to attach to the superior part of the linea aspera.
The muscles of the medial compartment of the thigh comprise the adductor group, consisting of the adductor longus, adductor brevis, adductor magnus, gracilis, and obturator externus.

As the obturator nerve emerges from the obturator canal to enter the medial compartment of the thigh, it splits into an anterior and a posterior division. The two divisions pass anterior and posterior to the adductor brevis. This unique relationship is useful in identifying the muscle during dissection and in anatomical cross-sections.
