摘　　要：[目的]比较Wiltse肌间隙入路与传统入路伤椎置钉内固定治疗无神经损伤胸腰椎骨折的临床疗效。[方法]回顾性研究2012年2月～2015年8月收治的87例单节段胸腰椎骨折患者,其中采用Wiltse肌间隙入路伤椎置钉6钉椎弓根钉-棒内固定47例,采用传统4钉椎弓根钉-棒固定40例。比较两组手术时间、术中出血量、术后引流量,术后1周、1年及2年伤椎矢状面Cobb角、末次随访腰背部疼痛VAS评分、ODI评分情况。[结果]87例患者手术顺利完成,未发生严重并发症。两组在手术时间上差异无统计学意义(P>0.05),但Wiltse组术中失血量与术后引流量均少于传统组,差异有统计学意义(P<0.05)。所有患者获得12～36个月随访,平均(23.13±8.15)个月。末次随访时,Wiltse组的VAS评分明显小于传统组,两组间差异有统计学意义[(3.13±1.85)vs(4.93±1.98),P<0.05]。Wiltse组的ODI明显小于传统组,两组间差异有统计学意义[(9.30±3.20)vs(12.20±3.11),P<0.05]。术后1周两组后突Cobb角的差异无统计学意义(P>0.05),但术后1年、2年时Wiltse组的后突Cobb角显著小于传统组,差异有统计学意义(P<0.05)。[结论]与传统后路内固定术相比,Wiltse肌间隙入路联合伤椎置钉短节段椎弓根螺钉内固定减少了术中损伤,有效复位和维持复位更好,是治疗单节段胸腰椎骨折更好的方法。[Objective] To compared the clinical efficacy of the pedicle screw-rod fixation plus screw placement on the injured vertebrae through Wiltse paravertebral approach versus the traditional pedicle screw-rod fixation through the midline approach for thoracolumbar fracture without nerve injury.From February 2012 to August 2015,a retrospective study was conducted on 87 patients with single segment thoracolumbar fractures without nerve injuries.Among them,47 patients were treated by the pedicle screw-rod fixation plus screw placement on the injured vertebrae with 6 pedicle screws through Wiltse paravertebral approach,while the remaining 40 patients received a classic pedicle screw-rod fixation with 4 pedicle screws through the traditional posterior midline approach.The clinical and radiographic parameters were compared between the two groups.All the 87 patients had operation performed smoothly without serious complication.Despite no a statistical difference in operation time between them（P〈0.05）,the Wiltse group had significantly less intraoperative blood loss and postoperative drainage than the traditional group（P〈0.05）.All patients were followed up from 12 to 36 months with an average of（23.13±8.15）months.At the latest follow up,the Wiltse group got significantly less visual analogue scale（VAS）of back pain than the traditional group[（3.13±1.85）versus（4.93±1.98）,P〈0.05].In addition,the Wiltse group was marked significantly less Oswestry disability index（ODI）than the traditional group[（3.13±1.85）versus（4.93±1.98）,P〈0.05].Although no statistical difference was noticed in the Cobb angle at 1 week postoperatively,the Wiltse group was proved statistically less Cobb angle at 1 and 2 years after operation（P〈0.05）.The pedicle screw-rod fixation plus screw placement on the injured vertebrae through Wiltse paravertebral approach has advantages of minimized intraoperative injuries,more effective fracture reduction and more efficient maintenance of the reduction over the trad
