Which nerve provides cutaneous innervation to the dorsum of the foot excluding the area between the hallux and second toe?

Which nerve provides cutaneous innervation to the dorsum of the foot excluding the area between the hallux and second toe?

• A. Superficial peroneal
• B. Deep fibular
• C. Saphenous
• D. Sural

Answer: (A)

The key idea is how the skin of the dorsum of the foot is innervated by nerves from the common fibular distribution. The superficial peroneal nerve supplies the majority of the dorsal surface of the foot. The only part of the dorsum not covered by it is the first dorsal web space between the hallux and second toe, which is supplied by the deep peroneal nerve. The saphenous nerve covers the medial side of the dorsum near the big toe, and the sural nerve covers the lateral aspect. So, excluding the area between the hallux and second toe, the nerve providing cutaneous innervation to the dorsum of the foot is the superficial peroneal nerve.
