Nerve scarring can cause severe pain and dysfunction. Treatment of the scarred nerve frequently yields unpredictable results. A barrier wrap around the scarred nerve could be of benefit in preventing the recurrence of epineural scarring following neurolysis. The barrier would ideally be inert so as to not incite an inflammatory response, and be nondegradable. Veins fulfill both of these objectives. The desirable qualities of a barrier nerve wrap include a substance that decreases nerve scarring, does not constrict and thus compress the nerve, and improves nerve gliding. The primary indication for nerve wrapping is a nerve with adherent scar.
