目的研究比较胸腰椎损伤分型及评分系统(thoracolumbar injury classification and severity score，TLICS)与改良Load-sharing评分在胸腰椎骨折治疗中的可重复性。方法收集2008年10月-2011年10月我院胸腰椎骨折56例患者，根据TILCS系统评分方法及改良Load-sharing评分标准进行评估。3个月后再次评价TLICS系统和改良Load-sharing评分，比较两次评分结果，用Cohn加权Kappa系数检测两种分型评分系统指导下的评价体系可重复性。结果改良Load-sharing评分和TLICS评分分类的观察者内平均Kappa系数分别为0.741和0.832。结论胸腰椎损伤分型评分对骨折治疗方式的选择有重要意义，改良Load-sharing评分和TLICS评分分类均有较好可重复性，TLICS评分更具优势。“,” Objective To investigate the reproducibility of the improved Load-Sharing scoring and thoracolumbar injury classification and severity score(TLICS) classification systems in the treatment of thoracolumbar fracture. Method Fifty-six thoracolumbar fracture patients with complete clinical and radiologic data were enrolled. The TLCS and the improved Load-Sharing scoring classifications were determined and repeated three months later respectively. Intraobserver reproducibility t was tested by the Cohen Kappa test. Result The average intraobserver Kappa values for the improved Load-Sharing scoring and TLICS Systems were 0.741 and 0.832 respectively. Conclusion Thoracolumbar fracture classification system is very important for the choose of treatments. TLICS system may has the greater reproducibility than that of the improved Load-Sharing scoring.
