全脊柱截骨USS系统内固定治疗脊柱后凸

目的　观察一次性多平面全脊柱截骨配合通用脊柱内固定系统 (USS)内固定治疗脊柱后凸的疗效。　方法　 2 0 0 0年 1月～ 2 0 0 2年 9月对 31例脊柱后凸患者进行了手术治疗 ,其中休门氏病 2例 ,强直性脊柱炎伴脊柱后凸 2 9例 ;病程 6～ 2 8年。X线片示脊柱后凸角 (Cobb角 )平均 89°,其中小于 4 0°3例 ,4 0～ 80°17例 ,80～ 110° 9例 ,大于110°2例 ,平均 89°。将术后平均矫正度数与术前平均后凸角度进行对比求出平均矫正率 ,并对截骨融合率、内固定结构稳定性进行随访统计。　结果　术后 31例均获 6～ 31个月随访 ,平均 12个月。术后 Cobb小于 4 0° 3例 ,平均矫正 32°;4 0～ 80°17例 ,平均矫正 5 8°;80～ 110°9例 ,平均矫正 86°;大于 110°2例 ,平均矫正 12 0°。术后全组平均矫正 74°,平均矫正率为 83.15 % ;除 1例截骨平面近椎间盘未愈合 ,余 30例术后 3～ 6个月获得骨性愈合。无一例发生断钉、断棒及连接结构松脱。　结论　采用一次性多平面全脊柱截骨配合 USS系统内固定治疗脊柱后凸可达到稳定的三维固定 ,增加了脊椎融合率 ,提高了后凸角度矫正率 ,并可早期离床活动 ,无须外固定。

SURGICAL TREATMENT OF KYPHOSIS WITH UNIVERSAL SPINE SYSTEM

OBJECTIVE: To introduce a method to treat kyphosis with universal spine system (USS) and to evaluate its clinical effect. METHODS: From January 2000 to September 2002, 31 patients with kyphosis were treated with "one-stage total vertebral wedge-shaped osteotomy" and internal fixation of USS. The average follow-up time was 12 months (6-31 months). We observed the clinical effect with the spinal column Cobb before operation and after operation, and the osteotomy confluence rate. RESULTS: In 31 patients, the average angle (Cobb) was 89 degrees before operation and 74 degrees after operation; the average rate of correction was 83.15% and the average rate of osteotomy confluence was 96.77%. No screw and rod broke and loosened. CONCLUSION: The USS is the reliable internal fixation instrument for the treatment of kyphosis, can increase the osteotomy confluence rate and improve correcting rate.
