The lateral antebrachial cutaneous nerve as a highly suitable autograft donor for the digital nerve

The lateral antebrachial cutaneous and digital nerves were compared by a histomorphometric method in each patient from a series of patients in whom a digital nerve was grafted with the lateral antebrachial cutaneous nerve as donor. Statistical analysis by the paired Student's test of paired data sets from all patients showed that there was no significant difference between the two nerves in regard to the following parameters: fascicular area, area of the entire nerve bundle, and percent of the nerve bundle occupied by the actual nerve fascicles. These data, together with other observations reported here, strongly support the hypothesis that the lateral antebrachial cutaneous nerve closely resembles the original fascicular pattern of the digital nerve and is, therefore, a highly suitable donor for the digital nerve.
