Abstract

In 30 adolescent patients with 36 structural curves undergoing posterior spinal arthrodesis using Cotrel- Dubousset (CD) instrumentation, computer tomography (CT) was performed to evaluate the change in rotation and in the sagittal plane. The average preoperative Cobb angle was 51.7°, and improved to 18.7° postoperatively, or 64.9%. The angle of rotation of the apical vertebra relative to the anterior midline of the body (RA_ML) improved from 27.9° preoperatively to 21.5° postoperatively (23.9%). The angle of rotation relative to the sagittal plane (RA_sag) improved from 15.2° preoperatively to 13.4° postoperatively (14.3%). The kyphotic angle increased an average of 10.6° in the 14 patients whose preoperative angle was less than 25°. As measured by CT, CD instrumentation improves both the rotational and sagittal plane deformities better than that reported for other systems.
