Where does the damage associated with sural nerve injury typically manifest?

• A. Medial side of the ankle
• B. Lateral skin of the ankle
• C. Plantar surface of the foot
• D. Dorsal foot area

Answer: (B)

The sural nerve is a sensory nerve that primarily provides sensation to the skin of the lateral aspect of the foot and the lower leg. When there is an injury to the sural nerve, the damage is usually evidenced by altered sensation, such as numbness or tingling, specifically in the lateral region of the ankle and along the lateral aspect of the foot. The correct manifestation of sural nerve injury aligns with its anatomical distribution, which does not include the medial side of the ankle or plantar surfaces typically associated with other nerves, such as the tibial nerve. Additionally, the dorsal area of the foot is primarily innervated by other nerves, such as the superficial peroneal nerve. Therefore, the lateral skin of the ankle is the area that is typically affected by sural nerve injury, leading to sensory deficits or changes in that specific region.
