For over a century, the plain radiograph has been used to measure and predict the development of pediatric hip conditions. Classic measurements, such as the acetabular index, the center-edge angle, and the migration percentage, have stood the test of time and remain the default tools for any pediatric orthopaedic surgeons. However, in contemporary research, the terminology regarding these measurements has become markedly inconsistent. A substantial number of synonyms, acronyms, and similar, but not identical, terms are used to label measurements. This is perhaps unsurprising, considering decades of use and numerous suggested modifications. The results of treatment cannot be reliably compared if the measured parameters are not identical, and scientific analysis of disease requires consistent terminology. In this review, we aim both to provide historical definitions and identification of radiographic landmarks commonly used in three parameters of interest on pediatric AP radiographs and to examine the variability of landmarks and definitions in contemporary research.
一个多世纪以来，普通X线片一直被用于测量和预测小儿髋关节疾病的发展。经典测量方法，如髋臼指数、中心边缘角和移位百分比，经受住了时间的考验，仍然是所有小儿骨科医生的默认工具。然而，在当代研究中，关于这些测量的术语已经明显不一致。大量的同义词、首字母缩略词以及相似但不完全相同的术语被用来标记测量结果。考虑到数十年的使用以及众多建议的修改，这或许并不奇怪。如果测量参数不一致，治疗结果就无法可靠地进行比较，而疾病的科学分析需要一致的术语。在本综述中，我们旨在既提供小儿前后位X线片上三个感兴趣参数常用的影像学标志的历史定义和识别方法，又探讨当代研究中标志和定义的变异性。
