Peripheral nerve injuries include: Brachial plexus injury. Peroneal nerve injury (foot drop) Spinal accessory nerve injury. Peripheral nerve injuries can be mild or serious, and can be graded on the Sunderland scale, which defines five degrees of severity. Injuries may be treated with nonsurgical or surgical therapy.
