The adductor canal (AC), also known as the subsartorial or Hunter canal, is a conical musculoaponeurotic tunnel passing through the distal aspect of the thigh's middle third (see Image. Adductor Canal). This region is a passageway for several neurovascular structures from the femoral triangle to the adductor hiatus.[1][2] Major structures passing through the AC include the superficial femoral artery, femoral vein, and saphenous nerve. The nerve to the vastus medialis is also often mentioned as traversing the AC, but some authors challenge this claim. The AC is a clinically relevant anatomical landmark, as disease and trauma can involve this region. The AC is also an increasingly common nerve block site for knee, ankle, and foot surgeries.[3][4][5][6] This review discusses AC's anatomy and clinical relevance.
