The adductor canal (subsartorial or Hunter’s canal) is an aponeurotic tunnel in the middle third of the thigh, extending from the apex of the femoral triangle to the opening in the adductor magnus, the adductor hiatus.
Contents
Boundary
It courses between the anterior compartment of thigh and the medial compartment of thigh, and has the following boundaries:
It is covered in by a strong aponeurosis which extends from the vastus medialis, across the femoral vessels to the adductor longus and magnus.
Contents
The canal contains the superficial femoral artery, femoral vein, and branches of the femoral nerve (specifically, the saphenous nerve, and the nerve to the vastus medialis). The femoral artery with its vein and the saphenous nerve enter this canal through the superior foramen. Then, the saphenous nerve and artery and vein of genus descendens exit through the anterior foramen, piercing the vastoadductor intermuscular septum. Finally, the femoral artery and vein exit via the inferior foramen (usually called the hiatus) through the inferior space between the oblique and medial heads of adductor magnus.
Eponym
The eponym 'Hunter’s canal' is named for John Hunter.
