后路单个椎间隙固定治疗胸腰椎屈曲型压缩骨折的评价

Posterior single intervertebral fixation in treatment of thoracolumbar flexion compression fractures

目的经后路整复胸腰椎屈曲型压缩骨折,相邻的上一椎间隙进行固定,经椎弓根椎体内植骨和后外侧植骨融合,评价其脊柱矫正度.方法对接受手术的23例患者术前、术后的影像学资料进行总结,并对结果进行分析.结果23例患者经12mo随访,测出X光片术前和术后伤椎前缘平均高度.术前平均为19mm,术后1wk平均为31mm,术后12mo平均为29mm.骨折后成角的Cobbs角术前平均为21°,术后1wk平均为6°,术后12mo平均为9°.结论后路单个椎间隙固定治疗胸腰椎屈曲性骨折可行,复位好,远期矫正度有小部分丢失;可最大范围地保留其他椎间隙的功能,缩小了手术创伤范围.

AIM： To evaluate the correction degree of spine after posterior reduction, graft fusion and fixation of the upper adjacent intervertebral space in the treatment of thoracolumbar flexion compression fractures. METHODS ： Twenty-three patients with thoracolumbar flexion compression factures underwent the operation of posterior reduction, graft fusion and fixation of the upper adjacent intervertebral space. The preoperative and postoperative imaging findings were summarized and the results were analyzed. RESULTS： All cases were followed up for a period of 12 months. The mean height of anterior margin of injured vertebral bodies was 19 mm before surgery, and respectively corrected to 31 mm and 29 mm at the time of 1 week and 12 months after surgery. The mean of Cobb＇s angle was 21 ° before surgery and respectively corrected to 6° and 9° at 1 week and 12 months after surgery. CONCLUSION： Posterior fixation of single intervertebral space for treatment of patients with thoracolumbar flexion fractures can achieve a good reduction. Loss of correction degree is a little during the long-term follow-up. Besides, it can keep the function of other intervertebral spaces as much as possible.
