Spinal accessory nerve to triceps muscle transfer using long autologous nerve grafts for recovery of elbow extension in traumatic brachial plexus injuries.

Despite continuous improvement and expansion of reconstructive options for traumatic brachial plexus injury, options to reinnervate the triceps muscle remain somewhat sparse. This study describes a novel option, using a spinal accessory nerve transfer to the long head of the triceps muscle with an intervening autologous nerve graft. The resulting quality of elbow extension and factors that influence outcome are discussed.
