What is n. peroneus communis?

The n. peroneus communis, also known as the common peroneal nerve, is a nerve that branches off from the sciatic nerve in the thigh and runs down the leg. It provides motor function and sensory innervation to the muscles of the lower leg and foot. The nerve is vulnerable to injury and can result in conditions such as foot drop or sensory loss if damaged. Treatment for common peroneal nerve injuries can include physical therapy, orthotics, or surgery depending on the severity of the injury.
