A novel quantitative, computerized, and, therefore, highly objective method is presented to assess the degree of total radical acetabular bone loss. The method, which is abbreviated to "TrABL", makes use of advanced 3D CT-based image processing and effective 3D anatomical reconstruction methodology. The output data consist of a ratio and a graph, which can both be used for direct comparison between specimens. A first dataset of twelve highly deficient hemipelves, mainly Paprosky types IIIB, is used as illustration. Although generalization of the findings will require further investigation on a larger population, it can be assumed that the presented method has the potential to facilitate the preoperative use of existing classifications and related decision schemes for treatment selection in complex revision cases.
本文提出了一种新颖的定量、计算机化且因此高度客观的方法，用于评估髋臼全层骨质流失的程度。该方法简称为“TrABL”，利用了基于先进三维CT的图像处理和有效的三维解剖重建方法。输出数据包括一个比率和一张图表，二者均可用于标本之间的直接比较。以十二个严重缺损半骨盆的首个数据集为例，主要为Paprosky IIIB型。尽管要将这些发现推广到更大规模人群还需要进一步研究，但可以认为，所提出的方法有潜力促进现有分类方法在术前的应用，以及在复杂翻修病例中用于治疗选择的相关决策方案。
