Traumatic peripheral nerve injuries are among most important cause of physical disability among young adults. Most partial injuries and some complete injuries recover without operative intervention, with early return of function appearing to be the most significant prognostic factor in these cases.

Although some nerve injuries recover spontaneously, in some cases surgery is the only therapeutic option for the improvement of neurological deficits or control of neuropathic pain. We aimed to review the classification and management of peripheral nerve injury, with emphasize on clinical aspect
