Abstract: The present invention is a cervical cage device designed to perform an intersomatic arthrodesis. It is made from a flat and elongated metal plate (1) wider in its central part (2), whose edges, except in the central part, have teeth (30, 40). The plate (1) is bent to form an open ring and the teeth (30, 40) are oriented toward the central part of the cage, so that the ends of the ring have the shape of spears.
