Biomechanical assessment of anchored cervical interbody cages: comparison of 2-screw and 4-screw designs.

Abstract

BACKGROUND A new anchored cervical interbody polyetheretherketone spacer was devised that uses only 2 integrated variable-angle screws diagonally into the adjacent vertebral bodies instead of the established device that uses 4 diagonal fixed-angle screws. OBJECTIVE To compare in vitro the stability provided by the new 2-screw interbody spacer with that of… (More)
