Finite element analysis of retrograde superior ramus screw of pubis for the treament of pelvic anterior ring fracture.

ABSTRACT:

Background

Retrograde superior ramus screw of pubis (SRSP) is a new kind of pelvic minimally invasive internal fixation apparatus developed by our team. The purpose of this study was to analyze the biomechanical stability of this new minimally invasive pelvic internal fixation device, and to provide this new device with theoretical basis for clinical application.

Methods

The Tile C1.3 pelvic fracture model was established. The posterior ring was fixed in the same way with two sacroiliac screws. And the anterior ring was fixed with SRSP, reconstruction plate, minimal invasive subcutaneous internal fixator (INFIX) and hollow screw respectively, to establish the finite element model of fracture-internal fixation. Finite element analysis was used to analyze the deformation and V
