Use of acellular allogeneic nerve transplants for nerve defects of the hand : Experience from a German hand surgery center

Peripheral nerve injuries are often encountered in traumatological care. The aim of this manuscript is to provide initial data, experiences and performance reports from Germany in the implantation of acellular human nerve transplants in peripheral sensory nerve defects of the hand and to put these data in the context of a comprehensive review of the literature. Of the patients 4 (7 digital nerves) were examined 6 months postoperatively and 5 patients (6 digital nerves) were examined 1 year after the operation (3 were also at the 6‑month examination). All patients had a clinical improvement after nerve reconstruction (≥ S3 according to the classification of sensory recovery of the Medical Research Council modified by Mackinnon and Dellon). Disadvantages of our clinical study are the small number of patients, the inhomogeneity (primary and secondary nerve reconstruction) and the lack of comparison with other nerve reconstruction methods.
