Anatomy
Course
The sural communicating branch of the common peroneal nerve contributes to the sural nerve.
It arises from the common peroneal nerve in the popliteal space and passes over the lateral head of the gastrocnemius muscle. About halfway down the leg, it joins with the medial sural nerve to form the sural nerve.
Supply
The sural communicating branch of the common peroneal nerve supplies sensory innervation to the lateral skin on the posterior aspect of the leg, as well as the skin on the lateral surface of the foot, via the sural nerve.
Clinical
Damage to the sural communicating branch of the common peroneal nerve will result in deficits in its region of distribution, such as pain, tingling and paraesthesia.
