1. A cage configured to be inserted between a plurality of vertebrae, the cage comprising planar inclined surfaces including an upper planar inclined surface and a lower planar inclined surface,
wherein the cage is configured to be supported while being inserted in an insertion direction to form an insertion angle with respect to an anterior aspect of the spine and being configured to be placed between the plurality of vertebrae,
wherein the upper and lower planar inclined surfaces are disposed from an anterior aspect to a posterior aspect of the plurality of vertebrae such that, when placed between the plurality of vertebrae, the upper planar inclined surface forms an upper angle with respect to an upper planar horizontal surface, and the lower planar inclined surface forms a lower angle with respect to a lower planar horizontal surface,
wherein the cage further comprises the upper planar horizontal surface connected to the upper planar inclined surface and disposed on an upper end portion of the cage, and the lower planar horizontal surface connected to the lower planar inclined surface and disposed on a lower end portion of the cage, the upper and lower end portions of the cage being configured to be placed adjacent to the anterior aspect of one of the plurality of vertebrae, respectively,
wherein the upper and lower planar horizontal surfaces are horizontally provided and configured to distribute a load applied to the anterior aspect of the plurality of vertebrae, and
wherein, in the cage:
an open growth space is formed in the upper and lower planar inclined surfaces for growth of the plurality of vertebrae; and
the upper and lower planar horizontal surfaces are provided to be completely filled to support the plurality of vertebrae.
