摘要：

      摘要 目的：本研究对青少年特发性脊柱侧凸者采用Rigo分型系统进行分型,比较其在不同观察者间的可信度和同一观察者内的可重复性。 方法：120例青少年特发性脊柱侧凸的X线片，交由脊柱科、影像科及支具矫形部各1名专家使用Rigo分型系统进行诊断分型。2周后将X光片再次交给他们进行分型。收集结果分别作不同观察者间可信度和同一观察者内可重复性的分析,计算Kappa值以检验一致性。 结果：脊柱科医师与影像科医师分型结果的Kappa值为0.942；脊柱科医师与支具师分型结果的Kappa值为0.914；影像科医师与支具师结果的Kappa值为0.895；可重复性平均值为91%，Kappa值为0.902。 结论：Rigo分型系统实用一致性好，临床医师及技师诊断分型时所产生的分歧少,适合临床应用。

Abstract:

      Abstract Objective: To evaluate the interrater and intrarater reliability of Chinese version of Rigo classification system. Method: One hundred and twenty cases of adolescences with idiopathic scoliosis were involved. Three raters, who were specialist in orthopedic (spine), imaging and prosthetics and orthotics respectively, evaluated the X-rays of those cases by Rigo classification system. The same raters re-evaluated the X-rays two weeks later after initial evaluation. All the evaluation results were recorded for interrater and intra-rater reliability analysis, and Kappa value was used to evaluate consistency. Result: Kappa value was 0.942 between spine doctor and imaging doctor, 0.914 between spine doctor and Orthotist, and 0.895 between imaging doctor and orthotist. The average repeatability was 91% in the same rater with a kappa value of 0.902. Conclusion: Rigo classification system is a reliable measurement, which could be recommended for both clinician and technician.
