Abstract

A histological and functional comparison of regeneration across a vascularized and conventional nerve graft was carried out in a clinical case. The two branches of the medial antebrachial cutaneous nerve were used to neurotize the median nerve at the wrist. The superficial branch of the radial nerve (vascularized nerve graft) and a conventional sural nerve graft were used as the interposition grafts between the two branches of the medial antebrachial cutaneous nerve and the median nerve. This nerve grafting procedure was carried out in two stages. The proximal neurorrhaphy was carried out 7 months prior to the distal nerve repair. Biopsies were taken from the distal portions of the vascularized radial sensory nerve and the conventional sural nerve at the time of the second procedure. Histological evaluation demonstrated superior regeneration across the vascularized nerve graft. Subjectively, the patient described better sensory recovery in the territory innervated by the vascularized nerve graft. Sensory testing in the two territories demonstrated better sensibility in the territory innervated by the vascularized nerve graft.
