Abstract
An interbody fusion cage has an externally threaded stem projecting from a domed outer end. A contoured plate is provided with an aperture receivable on the stem. The stem threads receive a nut to fix the plate to the cage. Bone screws anchor the plate to vertebral bodies. A hemispherical surface on the plate and surrounding the stem-receiving aperture and bearing on the dome, accommodates universal angulation of the plate relative to the cage. In addition to a cage installation tool, there is a plate installation tool assembly including a cage installer, a plate holder, a nut holder and cage adjuster, a nut driver, and a plate holding prong controller.
