From: The effect of metal artefact on the design of custom 3D printed acetabular implants
Pre-operative planning workflow. The acetabular bone loss, or defect size, was estimated on an implant-based analysis consisting of filling the defect with the future implant (a and b), the implant geometry, flanges and screw holes were designed to enhance implant to bone surface area (b). The selection of component types aimed at restoring joint biomechanics, centre of rotation and offsets (c and d)
