THREADED FUSION CAGE WITH ENHANCED ANTERIOR SUPPORT

摘要

A fusion cage (1) is disclosed in the present application. The cage (1) has an overall generally cylindrical shaped body (10) with portions removed and with an outer surface (11) located on and defined by an exterior of a wall (12). An inner chamber (13) is also defined by an interior of the wall (12). The wall (12) includes upper and lower fenstrations of windows and (17) as well as side windows (20). The sides of the cage body (10) are truncated and channeled to produce channels (21) and (22) so as to reduce weight and size and to allow for mating with a tool. The front wall (25) allows for the packing of the chamber (13) during the installation process. The thread (30) is discontinuously wound around the surface (11) and gradually decreases in depth as it approaches the front wall (25).
