摘要：Because of the minimal soft tissue injury, the laparoscopic-assisted internal fixation is a promising technique in fixing the pelvic anterior ring fracture. The aim of this study was to investigate the biomechanical performance of the laparoscopic-assisted plate by the finite element method. Four kinds of implants were investigated, that is, the laparoscopic-assisted plate (LAP), the percutaneous anterior pelvic bridge (PAPB), the transramus intraosseous screw (TIS), and the open reduction (OR). The stability of the implants was investigated under three loading cases, showing that when the LAP was used, the stress at the fracture site was smaller than that at other parts, while for other implants, the high stress was always around the fracture site. In conclusion, the LAP demonstrated a good biomechanical performance in fixing the pelvic anterior ring fracture and is a promising technique in clinical applications.
