Biomechanical differences in pelvic ring reconstruction after Type 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 gradual stress and displacement distribution. Conversely, the modular prosthetic reconstruction shows significant stress concentration at the pubic symphysis region
