Object End-to-side neurorrhaphy has recently became popular for peripheral nerve repair. Although this method is mainly indicated in nerve defects in which there is an absent proximal nerve stump, bridging a motor nerve defect by coapting the proximal and distal ends of the defect to a neighboring mixed nerve in an end-to-side fashion has been another experimental use of this method. In this situation, however, the source of the regenerating axons is unclear because the axons in both the proximal end of the defect and the bridging intact nerve have the capacity for regeneration. The goal of this study was to identify the source of the regenerating axons. Methods In this experimental study, the authors used a sensory nerve to bridge a motor nerve defect so that they could elucidate the source of the regenerating motor axons in the distal part of the motor nerve. One advantage of using a sensory nerve was that it eradicated the risk of damaging another motor nerve. Tests used in the analysis included gait evaluation, electrophysiological tests, and histological assessment. Conclusions Results of this study showed that, in the rat model, a sensory nerve can be used to bridge a motor nerve defect, thereby eliminating the need for nerve grafting.

The phenomenon of lateral sprouting of axons into an end-to-side sutured recipient nerve is well documented. The exact nature, however, still needs further investigation. Since 1996, we have been continuously involved in primate research as well as using this end-to-side nerve suture (ETSNS) method in clinical practice. Fifty-six patients with a variety of conditions, ranging from brachial plexus avulsion to digital nerve lesions, have been operated. From our experience, it seems that the best results achieved are proximal motor re-innervation (e.g. biceps) and distal sensory re-innervation (e.g. volar skin of the hand). The discussion will cover various aspects for ETSNS in the human patient, such as indications, parameters, technique, and the importance of rehabilitation. ETSNS restores function in conditions previously difficult to operate, and may replace nerve grafting in many instances. It provides an additional method in our armamentarium in peripheral nerve surgery.
