Outcomes of nerve reconstruction for radial nerve injuries based on the level of injury in 244 operative cases.
We report a single surgeon series of 244 patients with radial nerve injuries who had nerve repair, neurolysis, or nerve graft over a 17-year period. 44 patients had a Level I or infraclavicular injury, 37 had a Level II injury within the spiral groove of the humerus, 104 had a Level III injury from the lateral arm to antebrachial fossa and 64 had a Level IV injury affecting the posterior interosseous nerve. Nerve grafting was used most frequently in all groups, and was the only method of reconstruction for level II injury. At 21.5 months follow up, Level IV injuries had significantly better outcome of finger and thumb extension, while wrist extension recovered in at least 80% of the patients irrespective of the level of injury. The radial nerve recovered better if repaired or reconstructed within 5 months of injury.
