目的：探讨后路经伤椎椎弓根短节段固定治疗胸腰椎骨折的临床疗效。方法对21例胸腰椎骨折采用后路经伤椎椎弓根钉短节段固定手术，测量手术前后X线片上后凸角度的纠正及椎体高度恢复的情况。结果随访6~20个月，均取得良好的复位效果，影像学测量结果发现，手术前Cobb’s为(26.4±7.3)°，骨折椎体前缘高度(56.1±12.5)%，与术后及末期随访比较，差异有统计学意义。而手术后和随访末期的Cobb’s和骨折椎体前缘高度比较，差异无有统计学意义(P>0.05)。末期随访骨折均达到临床愈合。结论后路经伤椎椎弓根置钉短节段内固定治疗胸腰椎骨折，能很好地恢复伤椎高度、矫正后凸畸形，增加固定椎的牢靠性，是一种有效的治疗方法。

Objective To assess the clinical outcome of short segment fixation in combination of pedicle screw in injured vertebrae for thoracolumbar fractures. Methods Twenty-one cases of thoracolumbar fractures received short segment fixation combined with pedicle screw in injured vertebrae surgery. The protruding after angle correction and vertebral body height recovery situation were measured by X-ray film before and after surgery. Results All the patients were followed up for 6~20 months,achieved good reduction effect. The imaging measure-ment results found that before the operation Cobb’s angle was (26. 4 ± 7. 3),fracture fanterior flange height was (56. 1 ± 12. 5)%. Com-pared with after the operation and the end of follow-up of Cobb’ s and fracture fanterior flange height,the difference had statistical significance (P<0. 05). But between after the operation and the end of the follow-up of Cobb’s and fracture fanterior flange height,the difference had no statistical significance (P>0. 05). Conclusion Short segment fixation in combination of pedicle screw in injured vertebrae can restore the height of vetebra,rectify protrusion deformity,which is an effective method for thoracolumbar fracture.
