Retrospective Assessment of the Morphology of Acetabular Defects: A 3D Reconstruction Approach
In this study, we aim to develop a statistical shape model and use it to reconstruct the shape of acetabula with severe defects (Paprosky 3a-3b). This will allow us to visualise and assess the morphology of the missing bone.
