尽管已对确定肩峰形态的可靠性进行了检验，但到目前为止，还没有对观察者间和观察者间的可靠性进行分析，以确定肩峰突起的存在和大小。问题/目的本研究的假设是，在(1)确定肩峰突起的存在，(2)肩峰突起的大小，和(3)肩峰形态的确定方面，观察者间和观察者间的可靠性将很差。用两种技术测量了顶端端生生物：(1)端生体长和(2)端生体距。同时测定了肩峰的形态。观察者间和观察者内一致性采用组内相关和Kappa统计方法进行检验。结果观察者间信度为中等至中等，观察者内信度为中等。对终生体长的测量表明，观察者间和观察者内的可靠性较差。体表距离的测量显示，观察者间的可靠性较差，观察者内的可靠性中等。在确定肩峰形态方面，观察者间和观察者内的可靠性分别为中等和良好。结论受过团契训练的肩部外科医生在确定是否存在肩峰终生真菌方面具有中等到中等的可靠性。然而，观察者在测量胚芽的大小方面的可靠性很差。这项研究表明，在测量胚芽大小时，胚芽-体长可能比胚芽长度更可靠。
BackgroundAlthough the reliability of determining acromial morphology has been examined, to date, there has not been an analysis of interobserver and intraobserver reliability on determining the presence and measuring the size of an acromial enthesophyte.Questions/PurposesThe hypothesis of this study was that there will be poor intraobserver and interobserver reliability in the (1) determination of the presence of an acromial enthesophyte, (2) determination of the size of an acromial enthesophyte, and (3) determination of acromial morphology.Patients and MethodsFifteen fellowship-trained orthopedic shoulder surgeons reviewed the radiographs of 15 patients at two different intervals. Measurement of acromial enthesophytes was performed using two techniques: (1) enthesophyte length and (2) enthesophyte–humeral distance. Acromial morphology was also determined. Interobserver and intraobserver agreement was determined using intraclass correlation and kappa statistical methods.ResultsThe interobserver reliability was fair to moderate and the intraobserver reliability moderate for determining the presence of an acromial enthesophyte. The measurement of the enthesophyte length showed poor interobserver and intraobserver reliability. The measurement of the enthesophyte–humeral distance showed poor interobserver reliability and moderate intraobserver reliability. The interobserver and intraobserver reliability in determining acromial morphology was found to be moderate and good, respectively.ConclusionsThere is fair to moderate reliability among fellowship-trained shoulder surgeons in determining the presence of an acromial enthesophyte. However, there is poor reliability among observers in measuring the size of the enthesophyte. This study suggests that the enthesophyte–humeral distance may be more reliable than the enthesophyte length when measuring the size of the enthesophyte.
