Peripheral nerve injury (PNI) can be a devastating and life-changing condition, normally caused from traumatic and iatrogenic events. Proper treatment of PNI remains difficult, with less than half of surgical procedures resulting in good or excellent outcomes. Subsequently, physicians should be aware of important principles that can help with management of acute PNI. I reviewed studies on PNI involving anatomy and classification schemes; workup such as electrodiagnostic tests, imaging procedures, and surgical indications; and operative treatment options (including nerve repair and use of nerve grafts and conduits, and nerve, muscle, and tendon transfers). Although treatment of these injuries continues to present a challenge to surgeons, a clear understanding of nerve anatomy and injury classification can be helpful in determining the indication and timing for surgical intervention, which may lead to successful outcomes.
