胸腰椎损伤分类及损伤程度评分系统的初步评估

目的 评估胸腰椎损伤分类及损伤程度评分系统(TLICS)的可信度(Interobserver reliability)和可重复性(Intraobserv er reproducibility),及其对胸腰椎损伤治疗的指导作用.方法 2006年1月～2007年6月收治脊柱胸腰段骨折48例,均行胸腰椎X线、CT、MRI检查,根据TLICS系统进行评定,3个月后进行再次评估.使用Cohen加权Kappa系数(Unweighted Co hen kappa coefficients)对观察者问一致性和可重复性进行分析.结果 计算TLICS亚类Kappa系数位于中度和较高可靠性之间(0.43～0.72).TLICS系统可重复性的Kappa系数则位于中度和较高度可重复性之间(0.55～0.76).TLICS系统诊断准确率为95.1%,敏感性87.5%,特异性96.8%.结论 TLICS分类系统具有较高的可靠性和可重复性,使用简单,易于掌握,此方法对于胸腰椎损伤的评估较全面和准确,可以作为患者临床治疗选择的依据.

Preliminary Evaluation of Thoracolumbar Spine Injury Classification and Severity Score System

Objective To evaluate the interobserver reliability and intraobserver reproducibility of the thoracolumbar spine injury classification and severity score(TLICS) and identify the clinical decision-making in the treatment of thoracolumbar spine injury.Methods Forty-eight consecutive patients with thoracolumbar vertebra fracture were enrolled in this study.Each of these patients underwent a thorough history and serial physical examinations followed by a comprehensive radiographic evaluation consisting of plain...
