Résumé :	Nerve wrap protectors are bioabsorbable synthetic materials made of collagen or extracellular matrix that provide a non-constricting encasement for injured peripheral nerves. They are designed to be used as an interface between the nerve and the surrounding tissue. After hydrated, they transform into a soft, pliable, nonfriable, easy to handle porous conduit. The wall of the nerve wrap has a longitudinal slit that allows to be placed around the injured nerve. ?his article presents the surgical technique for median nerve neurolysis and nerve coverage using a collagen or an extracellular matrix nerve wrap protector in 10 patients with recurrent or persistent carpal tunnel syndrome. All patients had a mean of three previous open carpal tunnel operations, which were not successful. The mean follow-up was 3 years. Under axillary nerve block anaesthesia with the use of pneumatic tourniquet, a standard open carpal tunnel approach was done incorporating the previous incision. Scar tissue was excised in a healthy bed and the median nerve was thoroughly released with external neurolysis. An appropriate length of nerve wrap protector was cut longitudinally according to the length of nerve release. The nerve wrap was loosely sutured with separate polypropylene sutures No. 7-0. A volar splint was applied for a mean of 2 weeks followed by progressive passive and active range of motion rehabilitation exercises of the wrist and fingers. At the last follow-up, all patients showed improvement of clinical symptoms, static two-point discrimination test and median nerve conduction studies, and absence of Tinel sign. Differences in outcome and complications with respect to the nerve wrap materials used were not observed.
