The sural nerve complex, highlighted in red.

The Sural Nerve Complex is a sensory nerve in the human body, located in the lower leg. It is a branch of the Tibial Nerve and the Common Fibular Nerve, and it provides sensory innervation to the skin of the lateral foot and lower lateral leg.

Anatomy

The sural nerve complex is formed by the union of two cutaneous branches of the lower leg: the Medial Sural Cutaneous Nerve (MSCN) and the Lateral Sural Cutaneous Nerve (LSCN). The MSCN is a branch of the tibial nerve, while the LSCN is a branch of the common fibular nerve.

Function

The sural nerve complex is purely sensory, providing sensation to the skin of the lateral foot and lower lateral leg. It does not provide motor innervation to any muscles.

Clinical Significance

Damage to the sural nerve complex can result in sensory loss or paresthesia (abnormal sensations) in the areas of the skin it innervates. It is often used as a donor nerve for nerve grafting procedures.
