经后路单节段椎弓根置钉复位内固定术治疗无神经功能损伤胸腰椎骨折

The treatment of no-neurological thoracolumbar fractures by single-segment transpedicula fixation

目的：探讨后路单节段椎弓根置钉复位内固定术治疗无神经功能损伤胸腰椎骨折的有效性及适应证。方法：2007年8月~2011年8月经后路单节段椎弓根置钉复位固定治疗无神经功能损伤胸腰椎骨折28例,观察术前、术后1年的临床表现和影像学各项指标。结果：患者均获得随访13~22个月,平均18.3个月。X线光影像检查测量指标术后椎体前高和后凸角均显著恢复（P〈0.05）,术后1年,未见上述指标的进一步丢失,影像学指标差异无统计学意义（P〉0.05）。结论：在严格限制手术适应证的前提下采取非融合的后路经椎弓根短节段固定治疗胸腰椎骨折患者可取得良好的临床效果。

Objective To evaluate the feasibility of single - segment transpedieula fixation for no - neurological thoracolumbar frac- tures. Method From August 2007 to August 2009, a total of 28 consecutive patients with no - neurological thoracolumbar fractures were managed with posterior pedicle screw instrumentation. Clinical and radiographic indicators were observed at a year before and after surger- y. Results All of the patients were followed up 13 -22 months and average 18. 3 months. The vertebral body height and kyphosis angle were significantly corrected immediately alter surgery （ P 〈 0. 05 ） and there were no significant progressive losses of the recovery of the vertebral body height and kyphosis angle at a year late after surgery（ P 〉 0. 05 ）. Conclusion Under the premise of strictly limited indications for surgery, the patients with thoracolumbar fractures are treat with non - fusion of short - segment pedicle screw fixation. Good clinical results can be obtained.
