Upper limb reinnervation in C6 tetraplegia using a triple nerve transfer: case report

Abstract

Restoration of elbow extension, grasp, key pinch, and release are major goals in low-level tetraplegia. Traditionally, these functions are achieved using tendon transfers. In this case these goals were achieved using nerve transfers. We present a 21-year-old man with a C6 level of tetraplegia. The left upper limb was treated 6 months after injury with a triple nerve transfer. A teres minor nerve branch to long head of triceps nerve branch, brachialis nerve branch to anterior interosseous nerve, and supinator nerve branch to posterior interosseous nerve transfer were used successfully to reconstruct elbow extension, key pinch, grasp, and release simultaneously.
