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 degrees, and improved to 18.7 degrees postoperatively, or 64.9%. The angle of rotation of the apical vertebra relative to the anterior midline of the body (RAML) improved from 27.9 degrees preoperatively to 21.5 degrees postoperatively (23.9%). The angle of rotation relative to the sagittal plane (RAsag) improved from 15.2 degrees preoperatively to 13.4 degrees postoperatively (14.3%). The kyphotic angle increased an average of 10.6 degrees in the 14 patients whose preoperative angle was less than 25 degrees. As measured by CT, CD instrumentation improves both the rotational and sagittal plane deformities better than that reported for other systems.
在30例患有36处结构性脊柱侧弯的青少年患者中，采用Cotrel-Dubousset（CD）器械进行后路脊柱融合术，通过计算机断层扫描（CT）评估旋转和矢状面的变化。术前平均Cobb角为51.7度，术后改善至18.7度，改善率为64.9%。顶椎相对于身体前中线（RAML）的旋转角度从术前的27.9度改善至术后的21.5度（改善率为23.9%）。相对于矢状面的旋转角度（RAsag）从术前的15.2度改善至术后的13.4度（改善率为14.3%）。在术前角度小于25度的14例患者中，后凸角平均增加了10.6度。通过CT测量，CD器械在改善旋转和矢状面畸形方面比其他系统的效果更好。
