Biomechanical differences in pelvic ring reconstruction after Type I + II resection: Comparing different reconstruction methods using 3D-printed hemipelvic endoprostheses (a) and modular hemipelvic endoprostheses (b) in four common physiological postures, the stress distribution is more uniform and gradual in the 3D-printed prosthetic reconstruction. However, in the modular prosthetic reconstruction, significant stress concentration is evident
