摘要

背景后路椎弓根螺钉固定已成为治疗胸腰椎爆裂性骨折的常用方法。然而,更多节段的额外固定是否能改善临床和放射预后仍不清楚。目的和目的本研究的目的是评估短节段合并螺钉与经椎弓根螺钉后路稳定治疗不稳定胸腰椎骨折的临床和影像学结果。患者和方法这是一项前瞻性回顾性比较临床试验,20例患者采用短节段合并螺钉,另外20例患者采用长节段固定。研究的持续时间从6到12个月不等。结果两组在角度矫正方面有显著性差异;然而,两组的角度矫正都有显著降低:A组多于B组,结论胸腰段短节段固定(包括椎体骨折)与长节段固定一样有效,椎管恢复良好,脊柱后凸角矫正良好,虽然长节段固定在影像学上效果更好,但临床效果相同,可以促进神经功能的恢复结果。

Comparative study between a short segment with incorporating screws versus long-segment pedicle-screw fixation in management of unstable thoracolumbar spine fractures
Background Posterior pedicle screw fixation has become a popular method for treating thoracolumbar burst fractures. However, it remains unclear whether additional fixation of more segments could improve clinical and radiological outcomes. Aim and objectives The aim of this study was to evaluate the clinical and radiological outcome of a short segment with incorporating screws versus long-segment posterior stabilization using transpedicular screws for management of unstable thoracolumbar spine fractures. Patients and methods This was a prospective retrospective comparative clinical trial with 20 patients’ short segment with incorporating screws and long-segment fixation in another 20 patients. The duration of the study ranged from 6 to 12 months. Results There is a significant difference between the two studied groups as regards angle correction; however, there is a significant reduction in angle correction in both groups: group A more than group B, and there is a significant difference between the two studied groups regarding complications that were more frequent in group B. Conclusion Short-segment fixation (including the fractured vertebrae) in the thoracolumbar region is as effective as the long segment with good spinal canal restoration and correction of kyphotic angle and may enhance the regaining of neurological function although better results were achieved radiologically by long-segment fixation while clinically they are the same results.
