The adductor (subsartorial) canal extends from the apex of the femoral triangle to the adductor hiatus. Which set of structures does it contain?

• A Femoral artery, obturator nerve, lymphatics, great saphenous vein
• B Femoral artery, femoral vein, saphenous nerve, nerve to vastus medialis ✓
• C Femoral vein, saphenous nerve, medial circumflex femoral artery, genitofemoral nerve
• D Femoral artery, femoral nerve, obturator artery, lymphatics

Explanation

The adductor canal contains the femoral artery and femoral vein, the saphenous nerve, and the nerve to vastus medialis. The femoral nerve itself ends just below the inguinal ligament and never enters the canal, which eliminates option D. The obturator nerve descends on the medial thigh outside this canal, and the great saphenous vein is a superficial vein that drains into the femoral vein at the saphenous opening rather than travelling in the canal.
