A fundamental goal of research in developmental dysplasia of the hip (DDH) has been the identification of radiographic quantitative factors predictive of long-term outcome. The rapid development of digital imaging modalities opens the possibility for more systematic, automated measurement of radiographs. The authors have developed a software program for the study of DDH that integrates a user interface to select, store, and edit prescribed landmarks on digital radiographs. These points are used to construct and display reference lines analogous to those commonly drawn on physical films. Measurements are stored as a printable text file and as a data record. The results of this study demonstrated very good intrarater and interrater reliability coefficients and intermethod validity coefficients for the digitizing program. If this program is added to a software reporting system, measurements can be done on a real-time basis and can be included in the patient's medical record.
发育性髋关节发育不良（DDH）研究的一个基本目标是确定能够预测长期预后的X线定量因素。数字成像技术的迅速发展为更系统、自动地测量X线片提供了可能。作者开发了一个用于DDH研究的软件程序，该程序集成了一个用户界面，用于在数字X线片上选择、存储和编辑规定的标志点。这些点用于构建和显示类似于在实体胶片上常用的参考线。测量结果以可打印的文本文件和数据记录的形式存储。本研究结果表明，该数字化程序具有非常好的同一观察者内和不同观察者间的可靠性系数以及不同方法间的效度系数。如果将该程序添加到软件报告系统中，测量可以实时进行，并可纳入患者的病历。
