What is the sensory map of the saphenous nerve?

• A. Travels with the great saphenous vein and supplies the dorsum of the foot
• B. Travels with the femoral artery and extends distally along the medial leg to the medial malleolus
• C. Loops around the fibular neck to supply the lateral leg
• D. Runs with the popliteal artery to the posterior leg

Answer: (B)

The saphenous nerve is a sensory branch of the femoral nerve that travels through the thigh in the adductor canal with the femoral artery (and vein) and then continues distally along the medial leg, riding with the great saphenous vein to reach the medial malleolus. It supplies the skin on the medial aspect of the leg and the medial side of the foot up to the medial malleolus. It does not innervate the dorsum of the foot or the lateral or posterior aspects of the leg.
