The sural nerve (short saphenous nerve) is a nerve in the leg. It is formed by the junction of the medial sural cutaneous with the peroneal anastomotic branch of the lateral sural cutaneous nerve, passes downward near the lateral margin of the tendo calcaneus, lying close to the small saphenous vein, to the interval between the lateral malleolus and the calcaneus.
It runs forward below the lateral malleolus, and is continued as the lateral dorsal cutaneous nerve along the lateral side of the foot and little toe (via a dorsal digital nerve), communicating on the dorsum of the foot with the intermediate dorsal cutaneous nerve, a branch of the superficial peroneal.
In the leg, its branches communicate with those of the collateral branches off of the tibial, and common fibular nerve.
The sural nerve subserves a purely sensory function, and therefore its removal results in only a relatively trivial deficit. For this reason, it is often used for nerve biopsy, as well as the donor nerve when a nerve graft is performed.
