Superficial fibular nerve and its branches (labeled as "Musculocutaneous" here)

The Superficial fibular nerve (also known as the superficial peroneal nerve) is a nerve in the human lower limb that provides sensation over the lateral aspect of the leg and the dorsum of the foot. It is a branch of the common fibular nerve, which itself is a branch of the sciatic nerve.

Anatomy

The superficial fibular nerve originates from the common fibular nerve, which is a branch of the sciatic nerve. It travels down the lateral compartment of the leg, innervating the fibularis longus and fibularis brevis muscles. It then pierces the deep fascia to become cutaneous and innervates the skin of the lower two-thirds of the lateral leg and dorsum of the foot.

Clinical significance

Damage to the superficial fibular nerve can result in foot drop, a condition where the individual has difficulty lifting the front part of the foot. This can be caused by a variety of factors, including trauma, nerve compression, and neuropathy.
