Sural nerve

The sural nerve is a sensory nerve in the calf region (sura) of the leg.

It is made up of branches of the tibial nerve and common fibular nerve, the medial cutaneous branch from the tibial nerve, and the lateral cutaneous branch from the common fibular nerve.

Once formed, the nerves runs down the mid calf to the ankle and along the skin from the mid-posterior popliteal fossa to just behind to the lateral malleolus and then under the malleolus and forward along the lateral aspect of the foot. The sural nerve supplies sensation to the skin of the lateral foot and lateral lower ankle.
