[The Dwyer operation in the surgical treatment of scoliosis].
The authors have used Dwyer's procedure in 50 patients with a maximum follow-up of 4 years. The average correction was 76 per cent--that is the average curve was 73 degrees before operation and 16 degrees after operation. The upper compensatory curve was also corrected from an average of 45 degrees to an average of 28 degreees. Associated kyphosis was corrected by 75 per cent in association with correction of rotation. In the follow-up, a loss of 7 degrees of correction in the main curve was noted. It was related to rupture of the cable (5 cases), to a high rate of non-union (50 per cent) and to too short a length of fixation. When curves were correctly fixed, loss of correction was only of 2 to 3 degrees. The main advantage of the Dwyer procedure is to allow limited fusion with horizontal levelling of unfused intervertebral spaces.
