Adductor Canal: Functional Anatomy
Advanced, Clinical Sciences: Anesthesia Procedures, Methods, and Techniques
The saphenous nerve traverses the adductor canal. This nerve carries superficial sensation of the medial leg to the ankle and foot. The nerve lies between the Vastus Medialis and Sartorius muscle. The femoral nerve gives a branch to the vastus medialis that provides motor function and traverses the adductor canal.
The block is performed with the patient supine with the leg abducted and externally rotated to gain access to the medial thigh. The adductor canal is roofed by the Sartorius muscle, laterally by the vastus medialis and posteriorly by the adductor longus. The canal also carries the femoral artery and vein.
