Are Suprapectineal Quadrilateral Surface Buttressing Plates Performances Superior to Traditional Fixation? A Finite Element Analysis

Acetabular fractures have a high impact on patient’s quality of life, and because acetabular are energy injuries, they often co-occur with other pathologies such as damage to cartilage that could increase related morbidity; thus, it appears primary importance developing reliable treatments for this disease. This work aims at the evaluation biomechanical performances non-conservative through finite element approach. Two pelvic plates models (the standard suprapectineal plate—SPP, quadrilateral surface buttressing plate—SQBP) were analyzed when implanted transverse or T-shaped fractures. The geometries adapted specific hemipelvis, mimicking bending action surgeon performs plate intraoperatively. Implemented tested in single leg stance condition. obtained results show using SQBP generates lower bone stress if compared SPP plate. Interfragmentary movement analysis shows guarantees greater stability In conclusion, seems worthy further clinical analysis, having resulted promising option treatment fractures, able reduce values get comparable, some cases superior, traditional fixation.
