摘要：
Representative embodiments are disclosed for a spinal disc device which is implantable between adjacent vertebral bodies. A representative spinal disc device comprises: a first transverse plate member； a first arcuate extension extending longitudinally from the first transverse plate member and having a first configuration； a second transverse plate member； and a second arcuate extension extending longitudinally from the second transverse plate member and having a second, mating configuration with the first configuration of the first arcuate extension and slideably moveable with respect to the first arcuate extension, with the first and second arcuate extensions further arranged to form a central through-channel between the first and second transverse plate members to hold bone graft material. In various embodiments, the first and second configurations of the first and second arcuate extensions are each a partially spherical, convex shell configuration providing for movement in both the sagittal and coronal planes for deformity correction.
