Abstract
Transection of peripheral nerves results in Wallerian degeneration of the distal stump with varying degrees of degeneration in the proximal stump. After degeneration, the proximal neuron undergoes regenerative changes to make an appropriate connection with the degenerated distal segment. To improve recovery, surgical techniques have evolved to facilitate connection of the proximal to the distal stump. Current surgical strategies include epineurial and group fascicular repair under minimal tension at the repair site. We discuss the widely accepted surgical approaches to the repair of peripheral nerves and the issues to consider when selecting the appropriate surgical technique. © 2004 Elsevier Inc.
