The sural nerve originates from a combination of either the sural communicating branch and medial sural cutaneous nerve, or the lateral sural cutaneous nerve. This group of nerves is termed the sural nerve complex.

Your sural nerve is just below your skin’s surface in the back of your lower leg (calf). It enables you to detect foot position and sensations, including touch, temperature and pain. Your sural nerve can help diagnose and treat complex nerve issues.

As the sural nerve is purely sensory function dysfunction results in only a relatively trivial deficit. For this reason, it is often used for nerve biopsy, as well as the donor nerve for nerve grafts.

What Is the Sural Nerve? The sural nerve is a cutaneous nerve: a nerve that transmits sensation to the skin. The sural nerve is located beneath the skin at the back of the calf of each leg.

2022年12月5日 · The sural nerve is a purely sensory nerve. Its main function is to provide the sensory supply for the posterolateral aspect of the distal third of the leg, lateral aspect of the …

2024年8月22日 · The sural nerve is a cutaneous nerve of the lower limb, formed by contributions from the tibial and common fibular nerves. It supplies the skin over the posterolateral leg and foot.

2023年11月2日 · The sural nerve is a cutaneous nerve, providing only sensation to the posterolateral aspect of the distal third of the leg and the lateral aspect of the foot, heel, and ankle. It is formed by terminal branches of the tibial and common peroneal nerves that join together in the superficial aspect of the distal third of the leg. It is purely sensory and easily …

2025年1月22日 · The sural nerve is a sensory nerve located in the lower leg. It arises from branches of the tibial nerve and common peroneal nerve. The sural nerve travels down the posterior aspect of the leg, running along the calf, and passes behind the lateral malleolus (the outer ankle bone).

2025年1月25日 · The sural nerve is one of the cutaneous sensory nerves of the leg and foot. It plays a significant role in the lower limb by providing sensory information to the brain about the condition of the calf and lateral foot tissues.

Your sural nerve runs down the back of your leg, behind the outside edge of your ankle and down the outside of your foot. Below, we take a closer look at why your sural nerve can become damaged, and how it is treated.
