Abstract: An implant for a bone connector includes an implant body, a hook portion, a fixing clamp and a movable clamp. The fixing clamp has a curved shape and supports a vertebral arch of a vertebra by grasping the vertebral arch. The implant body is provided on an upper portion of the fixing clamp. The hook portion over which a connecting member is hooked is provided on an upper portion of the implant body. Further, the movable clamp, which has a curved shape and grasps the vertebral arch, is provided on the upper portion of the implant body and is disposed to be opposed to the fixing clamp.

Abstract: A bone connector includes a first screw, a second screw and a coil spring. The first screw is screwed into one centrum. The second screw is screwed into another centrum. The coil spring connects an upper portion of the first screw to an upper portion of the second screw. The bone connector allows that a positional relation originally set between the centrums is changed in some degree.
