In order to compare short-segment stabilization with long-segment stabilization for treating unstable thoracolumbar fractures, we studied fifty patients suffered from unstable thoracolumbar burst fractures. Thirty of them were managed with long-segment posterior transpedicular instrumentation and twenty patients with short-segment stabilization. The mean follow up period was 5.2 years. Pre-operative and post-operative radiological parameters, like the Cobb angle, the kyphotic deformation and the Beck index were evaluated. A statistically significant difference between the two under study groups was noted for the Cobb angle and the kyphotic deformation, while, as far as the Beck index is concerned, no significant difference was noted. In conclusion, either the long-segment or the short-segment stabilization is able for reducing the segmental kyphosis and the vertebral body deformation postoperatively. However, as time goes by, the long-segment stabilization is associated with better results as far as the radiological parameters, the indexes and the patient's satisfaction are concerned.
为比较短节段固定与长节段固定治疗不稳定型胸腰椎骨折的效果，我们研究了50例不稳定型胸腰椎爆裂骨折患者。其中30例采用长节段后路经椎弓根内固定术治疗，20例采用短节段固定。平均随访期为5.2年。评估术前和术后的影像学参数，如Cobb角、后凸畸形和Beck指数。研究的两组之间在Cobb角和后凸畸形方面存在统计学上的显著差异，而至于Beck指数，则未发现显著差异。总之，长节段或短节段固定均能在术后减少节段性后凸和椎体变形。然而，随着时间的推移，就影像学参数、指标和患者满意度而言，长节段固定的效果更好。
