Estudio anatómico de la transferencia de los nervios accesorio y toracodorsal al nervio cubital en el gato

Abstract

A brachial plexus injury is one of the most severe pathologies of the upper limb, and also has severe sequels. In the actual state of the art, nerve transfers are being used as first line of therapeutic approach in the reconstruction of proximal functions of the upper limb. In this study 20 nerve transfers were made to the ulnar nerve of the cat, using the spinal accessory nerve (10 cases) or the thoracodorsal nerve (10 cases). The opposite side was used as control. During next year, reinnervation was assessed by electromyography, nerve and muscle histology and histochemical evaluation of the spinal cord. We found that motoneurons of both donor nerves are able to make partial reinervation of the ulnar nerve territory. © 2008 Sociedad Española de Cirugía Plástica, Reparadora y Estética (SECPRE).
