摘　　要：[目的]探讨特发牲脊柱侧凸治疗方法，总结应用CD-Horizon（CD-H）钉-棒系统与钉-钩-棒系统的治疗效果。[方法]自2000年1月-2004年1月，采用CD-H器械治疗85例特发性脊柱侧凸患者，其中钉-棒系统51例（A组），钉-钩-棒系统34例（B组），比较术前、术后与随访2年冠状面与矢状面的角度及旋转度。[结果]85例患者平均随访3年半，术后及随访2年时冠状面及矢状面矫正率A组明显优于B组（P〈Q05）。术后2年2组冠状面矫正度的丢失有明显的差异。2组患者旋转矫正Ⅰ～Ⅱ度。术前、术后及术后2年，2组Cobb’s角自身得分显示术后明显低于术前（P〈0．05），与术后2年随访得分相比无差异（P〉0．05）。[结论]CD-Horizon器械是治疗特发性脊柱饲凸比较有效的方法，钉-棒系统较钉-钩-棒系统相比效果更佳。[ Objective] To discuss the effective method of idiopathic scoliosis and evaluate the result of screw-rod and screw-hook-rod system. [ Method] From January 2000 to January 2004, 85 cases with idiopathic scoliosis were treated by CD- Horizon instrument. Fifty-one cases were corrected with pedicle screws system only （ group A）, 34 cases were applicated with pedicle hooks or vertebral plate hooks in thoracic vertebra, while with pedicle screws system in lumbar vertebrae （ group B）. The Cobb＇s angle of coronal plane and sagittal plane and horizontal plane malformation were compared in preoperative score, postoperative score and the score at 2 years follow-up. [ Result] The mean followed-up duration of 85 cases was three years and a hall The coronal plane and sagittal plane correction rate of group A was higher than that of group B at postoperative and 2-year follow-up （ P 〈 0. 05 ）. There was significant difference between the two groups in loss of correction in coronal plane at postoperalive 2 years. Rotation was corrected by Ⅰ to Ⅱ degree in two group. Compared with preoperative score, the postoperative score decre.ased significandy （P 〈 0. 05 ） in two groups. However, there was no marked difference between the postoperative score and 2-year follow-up （ P 〉 0. 05 ）. [ Conclusion ] Using CD-Horizon instrument is a very effective choice for patients with idio- pathic scoliosis. Pedicle screw-rod system offers a significandy better curve correction compared with screw-hook-rod system.
