The author had the opportunity to treat ten patients with paralysis of the trapezius muscle. His experience was drawn from the treatment of these cases. Most cases were the result of accidental injuries and half were of iatrogenic origin. The patients were markedly handicapped in using their extremities, namely, weakness in abduction and in such activities as fishing, playing tennis, golf, and other sports as well as simple tasks like combing their hair. The operation consisted of transferring the insertion of the levator scapulae. A fascial sling is used from the spinous processes of the upper dorsal vertebra to the spinal border of the scapula and lateral transfer of the rhomboid. The follow-up ranged from 3 to 22 years. All patients were followed from 2 to 20 years after the operation. The results were 75% good; 25% fair, although patients demonstrated much improvement compared with pre-operative status.
