目的:探究短节段椎弓根钉内固定对改善胸腰段脊柱骨折脱位患者Cobbs角的效果.方法:选取2017年1月-2017年9月期间我院收治的胸腰段脊柱骨折脱位患者40例患者作为研究对象,全部入选研究病例均给予短节段椎弓内固定治疗,对比患者术前、术后14d、术后30d伤椎椎体前缘压缩高度、Cobbs角等情况.结果:全部患者都顺利完成,而且术后复查结果表明均骨性愈合,而且未发生切口感染、神经损伤等并发症,而且与术前对比,术后14d、术后30d伤椎椎体前缘压缩高度、Cobbs角、VAS评分、JOA评分均明显改善(P＜0.05).结论:短节段椎弓根钉内固定对改善胸腰段脊柱骨折脱位患者能够有效改善患者伤情,促进愈合,降低并发症发生率,值得推广.“,”Objective: To explore the effect of short segment pedicle screw fixation on the improvement of Cobbs angle in patients with thoracolumbar spine fracture and dislocation. Method: From January 2017 -2017 year in September in our hospital 40 cases of patients with thoracolumbar fracture dislocation were treated as the research object, all enrolled patients were treated with short segment pedicle fixation, compared with preoperative and postoperative 14d, 30d anterior vertebral compression height and Cobbs angle etc..Result: All of the patients were successfully completed, and postoperative examination results showed that bony healing, and no infection, nerve injury and other complications, and compared with the preoperative, postoperative 14d, 30d anterior vertebral compression height, Cobbs angle, VAS score and JOA score were significantly improved (P ＜ 0.05).Conclusion:Short segment pedicle screw fixation can effectively improve the condition, promote healing and reduce the incidence of complications in patients with thoracolumbar spine fracture and dislocation, which is worthy of promotion.
