Quantitative Computerized Assessment of the Degree of Acetabular Bone Deficiency : Total radial Acetabular Bone Loss (TrABL)‎

الملخص EN

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.
