Reliability and repeatability analysis of simplified skeletal maturity scoring and thumb ossification composite index in the assessment of skeletal maturity inadolescent idiopathic scoliosis



Reliability and repeatability analysis of simplified skeletal maturity scoring and thumb ossification composite index in the assessment of skeletal maturity inadolescent idiopathic scoliosis



Zhonghua Yi Xue Za Zhi 98(43): 3479-3484



目的: 对比分析青少年特发性脊柱侧凸(AIS)的简化骨龄评分系统(SSMS)和拇指骨骺评分(TOCI)的可信度与可重复性,比较两种评分在AIS患者中的应用价值。 方法: 选取2006年10月至2013年8月于南京鼓楼医院门诊就诊的500例女性AIS患者为研究对象并随机抽取每例患者的1次随访。以SSMS评分和TOCI评分为标准,由三位脊柱外科医师分别对患者每次随访的左手掌正位片进行独立评分,两周后再次进行独立评分。收集结果,分别行不同观察者间可信度及同一观察者内可重复性分析。应用Kappa值比较分析两种评分方法的差异性。 结果: 三位医师使用SSMS评分共进行3 000次(500×3×2次)评分,包括1级50次,2级258次,3级962次,4级340次,5级315次,6级304次,7级589次,8级182次;观察者间可信度为76.8%~82.0%,Kappa值0.716~0.778;观察者内可重复性为75.8%~82.4%,Kappa值0.705~0.782。TOCI评分共计3 000次评分中,包括1级27次,2级183次,3级167次,4级171次,5级745次,6级536次,7级410次,8级761次;观察者间评分一致率为91.6%~92.4%,Kappa值0.897~0.907;观察者内评分一致率为90.4%~92.0%,Kappa值0.882~0.902。 结论: SSMS评分与TOCI评分均具有较高的可信度与可重复性,后者具有更高的可靠性,因此值得临床推广应用。.
