Adductor canal
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.

Structure
It is an intermuscular cleft situated on the medial aspect of the middle third of the thigh on anterior compartment of thigh, and has the following boundaries:
- Anteromedial wall - sartorius.
- Posterior wall - adductor longus and adductor magnus.
- Laterally - vastus medialis.
It is covered in by a strong aponeurosis which extends from the vastus medialis, across the femoral vessels to the adductor longus and magnus.
- Lying on the aponeurosis is the sartorius (tailor's) muscle.
Contents
The canal contains the subsartorial artery (superficial femoral artery), subsartorial vein (superficial femoral vein), and branches of the femoral nerve (specifically, the saphenous nerve, and the nerve to the vastus medialis).[1] 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.[2]
History
The eponym 'Hunter’s canal' is named for John Hunter.[3][4]
