This pilot study aimed to evaluate prospectively the use of inlet radiographs of the hip as an alternative method of the assessment of reduction after the surgical treatment of developmental dysplasia of the hip (DDH).
The children in this study underwent surgery between January 2013 and January 2015. All had inlet radiographs and CT scans post-operatively. Data were analysed by determining inter-observer reliability and intra-observer reproducibility, using the kappa value (K). Differences were settled by discussion between the two observers until a consensus was reached. The sensitivity and specificity of the radiographic and CT results were compared. A total of 26 radiographs were obtained from 23 children, with a mean age of 2.38 years (one to five).
Similar high levels of intra- and inter-observer agreement were observed (K = 0.834, 95% confidence interval (CI)). There was a high agreement between the radiographic and CT results (K = 0.834, 5% CI), with excellent sensitivity and a specificity of 95.5%.
These results suggest that inlet radiographs may be a reliable method of assessing the reduction of the hip after the surgical treatment of DDH. Cite this article: 2017;99-B:697-701.
本前瞻性初步研究旨在评估髋部入口位X线片作为发育性髋关节发育不良（DDH）手术治疗后复位评估的替代方法的应用。
本研究中的儿童于2013年1月至2015年1月接受手术。所有患者术后均进行了髋部入口位X线片和CT扫描。通过使用kappa值（K）确定观察者间可靠性和观察者内重复性来分析数据。分歧由两位观察者之间讨论解决，直至达成共识。比较了X线片和CT结果的敏感性和特异性。共从23名儿童获取了26张X线片，平均年龄2.38岁（1至5岁）。
观察到观察者内和观察者间的一致性水平相似（K = 0.834，95%置信区间（CI））。X线片和CT结果之间存在高度一致性（K = 0.834，5%CI），敏感性高，特异性为95.5%。
这些结果表明，髋部入口位X线片可能是评估DDH手术治疗后髋关节复位情况的可靠方法。引用本文：2017；99 - B：697 - 701。
