摘　　要：目的 对比分析分别采用长臂单轴经皮椎弓根钉与Sextant经皮椎弓根钉内固定治疗胸腰椎骨折的临床疗效。方法 回顾性分析我院自2011年3月-2014年2月61例患者采用经皮椎弓根钉棒系统内固定治疗单节段胸腰椎的临床资料,其中28例采用长臂单轴经皮椎弓根钉固定,33例采用Sextant系统。术后临床疗效按VAS评分及Macnab标准评估。结果 两组61例患者经过手术治疗后均得到随访,随访时间为18-24个月,平均21个月,VAS评分：长臂单轴钉组（1.8±0.95）,Sextant钉组（2.0±0.78）;Macnab标准：长臂单轴钉组优良率89.3%,Sextant钉组87.9%。测量术前术后及末次随访时病椎体前缘高度,计算椎体恢复的高度值;测出末次随访时与术后椎体高度差值即椎体复位后再丢失高度值,统计两组数据。结论 长臂单轴钉相比于Sextant在治疗单节段胸腰椎骨折上能取得与之相同的疗效,且病椎复位程度更显著、复位后不易再丢失。Objectives Contrastive analysis for the treatment effects ofthoracolumbar vertebral fractures fixated respectively by the methods oflong arm tmiaxial pedicle screws and Sextant＇s. Methods By the method ofretrospective analysis from Mar 2011 to Feb 2014,61 cases were treated by percutaneous pedicle screw rod system of internal fixation in treatment ofthoracolumbar single section, data of 28 patients with long arm tmiaxial percutaneous pedicle screw fixation, 33 cases using Sextant system. The postoperative clinical curative effects were evaluated by the VAS score and the Macnab criteria. Results Two groups of 61 patients were followed up after surgery, 18 to 24 months follow-up time, 21 months on average. VAS score ： long arm uniaxial nail group was （1.8±0.95）, Sextant nail group （2.0±0.78）, Macnab criteria ： long arm uniaxial nail group was 89.3%, Sextant nail group 87.9%. Measuring the preoperative and postoperative at the time of the last follow-up anterior flange height, calculating the postoperative and preoperative anterior altitude difference which was the height of vertebral body to restore value, measuring at the end of the time with postoperative follow-up vertebral height difference between the vertebral reset after the loss of height value, one group of data was compared with the other. Conclusion Long arm uniaxial percutaneous screw rod system internal fixation in treatment of single section thoracolumbar vertebral fractures can achieve the same clinical effect as the Sextant system, and at the aspects of the degree of vertebral reset and vertebral reset again after missing, long arm uniaxial percutaneous pin is better than a Sextant.
