Surgical treatment for spinal accessory nerve injury.

Abstract

We report on the surgical results of spinal accessory nerve injuries between 1992-2003. We operated on 10 patients (9 female, and 1 male) who had injuries of the spinal accessory nerve. All injuries were iatrogenic. The mean age of patients was 39.2 years (range, 20-57 years). The average interval between date of injury and surgery was 7 months (range, 4-12 months). All patients had stiffness and pain in the shoulder girdle. The average active abduction of the shoulder joint was 79.5 degrees (range, 60-100 degrees ) before surgery. End-to-end repairs were performed in 7 cases, and graft repairs were indicated in 3 cases. The mean follow-up period was 18.4 months (range, 8-36 months). The average active abduction of the shoulder joint was 171 degrees (range, 140-180 degrees ) at time of final follow-up.
