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.
Abstract: A surgical cable system and method for securing surgical cable around a portion of a human element (e.g., bone) are described. The surgical cable system may include an eyelet. The eyelet may be configured to be positionable within a cable opening formed in a portion of the bone, such that the cable may pass through the eyelet when the cable is inserted into the cable opening. The eyelet may prevent the cable from contacting the bone portion proximate the cable opening, thus protecting the bone portion from damage due to, e.g., friction from motion of the cable against the bone portion. In an embodiment, the eyelet includes a single eyelet member. In an alternative embodiment, the eyelet includes an eyelet member and at least one endpiece connectable to the eyelet member. In an alternative embodiment, the eyelet includes two eyelet members. The two eyelet members may be configurable to form a fixable engagement.
