  • Title: A comparison of suture and tubulization nerve repair techniques in a primate.
    Author: Hentz VR, Rosen JM, Xiao SJ, McGill KC, Abraham G.
    Journal: J Hand Surg Am; 1991 Mar; 16(2):251-61. PubMed ID: 1850770.
    Abstract:
    This study compared standard methods of nerve repair, epineurial or perineurial sutures with a technique termed fascicular tubulization using a biodegradable polyglycolic acid tube in a nonhuman primate model. Electrophysiologic analysis demonstrated that the percentage of proximal axons that conducted across the repair site did not significantly differ among the three techniques while epineurial suture repairs were associated with significantly longer conduction delays across the repair site compared with the other two techniques. Even though fascicular tubulization using the current polyglycolic acid tube resulted in regeneration equal to the currently perceived best suture repair technique, associated technical problems with the current tube design indicate that this fascicular tubulization technique cannot, at present, be considered as an alternative to present clinically used nerve suture techniques.
