Information about Adductor Canal

The femoral artery.
Latincanalis adductorius
subject #157 627
Dorlands/Elsevier c_04/12208510
The adductor canal (Subsartorial/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.

It is bounded, in front and laterally, by the Vastus medialis; behind by the Adductor longus and magnus; and 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 muscle.

The canal contains the femoral artery and femoral vein, the saphenous nerve, and the nerve to the Vastus medialis.

The adductor magnus is a large triangular muscle, situated on the medial side of the thigh.

The portion which arises from the ischiopubic ramus (a small part of the inferior ramus of the pubis, and the inferior ramus of the ischium) is called the "adductor portion", and the

The adductor hiatus is the termination of the adductor canal at the knee, in the adductor magnus.

The femoral artery and femoral vein pass through the hiatus in adductor magnus. After they do, they are called the popliteal artery and popliteal vein.
