Fig. 6From: Reliability and validity test of a novel three-dimensional acetabular bone defect classification system aided with additive manufacturingA A 62-year-old female was diagnosed with left hip prosthetic aseptic loosening 20 years after THA. B-C Am model showed uncontained defects in the posterosuperior acetabulum. The vertical stability could be achieved by reconstructing the posterosuperior stress-bearing acetabulum with augments with wing.
