[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.

[The dwyer operation in the treatment of paralytic scoliosis with oblique pelvis].

Pelvic obliquity due to spinal deformity is a well defined syndrome. Its natural history is related to the evolution of the scoliosis. The authors describe two types of pelvic obliquity--total pelvic obliquity in which the sacrum is the lowest vertebra of the lumbar curve and subtotal pelvic obliquity in which there is some compensation between L5 and the sacrum. Seventeen patients were operated on. The Dwyer's procedure was found to be satisfactory in total pelvic obliquities from the point of view of correction and stabilization. In subtotal pelvic obliquity, an additional lumbosacral fusion by a posterior approach was found to be necessary.
