发明名称 METHOD AND APPARATUS FOR DENS FRACTURE FIXATION
摘要 Embodiments of the present invention provide methods, apparatuses, and systems for fixing dens fractures. The mode of failure for screw fixation of C2 dens fractures is often via cut-out at the anterior body. In an embodiment, securing a plate, such as a locking plate, to the anterior surface of the vertebra attached directly to an interfragmentary screw may reduce potential for anterior screw cut-out and improve construct strength. Plate supplementation of anterior screw fixation of Type II dens fractures thus improves construct strength and changes the failure mechanism from anterior screw cut-out to posterior displacement of the screw, thus improving clinical outcomes for these fractures.
