Nerve grafting in the repair of complicated peripheral nerve trauma.

Peripheral nerve trauma has been a challenge to surgeons, with significant advances in the surgery of repair occurring in major wars. The standard method of treatment involving wide mobilization and end-to-end suture to close traumatic gaps in peripheral nerves has not produced consistently acceptable results, particularly with large gaps. However, with the recent development of microsurgical techniques and instrumentation, the method of interfascicular nerve grafting has been applied to selected patients with trauma problems of the peripheral nerve, by resecting and autogenous nerve grafting at staggered levels to distribute scar formation, followed by plaster immobilization for 3 weeks. Ten patients are reported, with motor nerve recovery ranging from M2 to M4 and sensory recovery, S2-S4 (See Table I), based on Seddon's classification (11).
