Figure 3: A young man, 9 months after a complex laceration at the elbow (a), where the ulnar nerve had been found to be severed and was acutely repaired by a trauma surgeon, had persistence of a complete motor palsy on follow up (b). It was elected to perform a distal AIN (pronator quadratus branch) (triangular arrow panel) (c) to ulnar nerve motor fascicle transfer (lower vessel loop in panel) (c). After neurolysis and mobilization, the ulnar nerve motor branch was cut very proximally so that it could easily reach the AIN fascicle (cut distally) for a planned tension-free repair (d)
