【摘要】：目的：分析研究椎弓根钉固定治疗青少年多节段非相邻型脊柱骨折的疗效。方法：回顾性研究2005年1月至2013年12月收治的青少年多节段非相邻型脊柱骨折患者中接受椎弓根钉内固定手术治疗的患者14例。对不同患者，依据骨折分型分别行长节段连续固定或短节段分别固定。通过对比术前、术后、随访X线平片、CT、MRI，对伤椎前缘高度（AVH），伤椎椎体角度等指标进行观察及测量。通过统计学方法得出各个指标之间的变化与矫正角度丢失之间的关系。结果：患者术后伤椎椎体前缘高度百分比、伤椎椎体角度与术前比较,均较术前明显改善（P0.05）；本组术后结果与末次随访比较无显著性差异，而伤椎椎体后缘高度百分比与术前比较无显著性差异（P0.05）。结论：椎弓根螺钉长节段连续固定或短节段分别固定，都是治疗MNSF的有效方法。神经减压术后患者神经功能可以得到一定程度的改善。
[Abstract]:Objective: To study the effect of pedicle screw fixation in the treatment of multiple segmental non adjacent spinal fractures in adolescents.
Methods: a retrospective study from January 2005 to December 2013 were teenagers multiple noncontiguous spinal fracture patients received pedicle screw fixation operation in 14 patients. For different patients, according to the type of fracture were long segmental fixation or continuous short segments were fixed. By comparing the preoperative, postoperative follow-up X-ray CT, MRI, of anterior vertebral height (AVH), vertebral angle index were observed and measured. The relationship between the change of statistical methods to calculate each index between the correction angle loss.
Results: postoperative anterior vertebral height percentage, compared with preoperative vertebral angle, were significantly improved compared with preoperative (P0.05); this group were compared with the results of the last follow-up had no significant difference, and the vertebral vertebral height percentage compared with preoperative had no significant difference (P0.05).
Conclusion: long segmental pedicle screw fixation or short segment fixation are effective methods for the treatment of MNSF. Neurological function can be improved to some extent after decompression.
