CDHorizon器械治疗特发性脊柱侧凸临床探究 　 作者：郝定均，贺宝荣，李毅，吴起宁，王晓东，刘团江，宋宗让 【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＜0.05）。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侧凸比较有效的方法，钉-棒系统较钉-钩-棒系统相比效果更佳。 【关键词】 特发性脊柱侧凸； CDHorizon椎弓根钉； 临床疗效 　　Clinical study of CDHorizon in idiopathic scoliosis∥ 　　Abstract：［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 half.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 postoperative 2 years.Rotation was corrected by Ⅰ to Ⅱ degree in two groups.Compared with preoperative score,the postoperative score decreased significantly（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 idiopathic scoliosis.Pedicle screwrod system offers a significantly better curve correction compared with screwhookrod system. 　　Key
