Hand, Wrist, Forearm, and Arm Replantation.

Level of injury plays a significant role in decisions to perform replantation, with improved function, nerve regeneration, and decreased rate of reperfusion injury for injuries at the distal forearm or wrist compared with proximal injuries. The principles of a functional and sensate outcome dictate replantable parts, whereas patient comorbidity, expectations, and safety dictate patient candidacy. Vascular grafts are an expected part of the operation, and the contralateral arm or a lower extremity should be prepped into the surgical field. Despite diminished function, patient satisfaction and independence remain high after a major upper extremity replantation.
