Abstract

Various classification systems have been proposed for fractures of the distal radius, but the reliability of these classifications are seldom addressed. The objective of this study was to determine the interobserver and intraobserver reliability of the Cooney classification. Five orthopaedic surgeons with more than 10 years' experience in orthopaedic trauma assessed 43 sets of radiographic files according to the Cooney classification separately. Kappa statistics were used to analyse the interobserver and intraobserver reliability. There was moderate and substantial interobserver and intraobserver reliability of the Cooney classification without subtype, but only slight reliability when the subgroups were considered. These results question the value of this classification system for treatment decision making.

摘要

针对桡骨远端骨折已提出了多种分类系统，但这些分类的可靠性很少被提及。本研究的目的是确定Cooney分类的观察者间和观察者内可靠性。五名在骨科创伤方面有超过10年经验的骨科医生分别根据Cooney分类对43套放射影像文件进行评估。采用Kappa统计分析观察者间和观察者内可靠性。Cooney分类在不区分亚型时观察者间和观察者内可靠性为中度和高度，但在考虑亚组时可靠性仅为轻度。这些结果对该分类系统在治疗决策中的价值提出了质疑。
