Biomechanical differences in pelvic ring reconstruction after Type I + II + III resection: Comparing different reconstruction methods using 3D-printed hemipelvic prostheses (a) and modular hemipelvic prostheses (b) in four common physiological postures, the 3D-printed prosthetic reconstruction exhibits a more uniform and natural stress and displacement distribution, closely resembling a normal pelvis. However, the modular hemipelvic prosthesis shows evident stress concentration at the pubic symphysis and CS fixator regions
