Fig. 1From: Biomechanical and clinical outcomes of 3D-printed versus modular hemipelvic prostheses for limb-salvage reconstruction following periacetabular tumor resection: a mid-term retrospective cohort studyThree-Dimensional finite element models of pelvic defects post tumor resection and reconstruction: 3D FE models illustrating typical pelvic defects after acetabular tumor resection and reconstruction using 3D printing or modular hemipelvic prostheses. Key components (ilium, sacrum, prosthesis, and screws) are assembled in the models. The transformation from cortical bone to cancellous bone models is demonstrated through a global offset of "-2.0 mm." Internal cancellous bone regions are marked with asterisks (*)Back to article page
