摘要：
A vertebra implant is provided that includes an elongate body with a first end configured to mate the first end to a first location on a vertebra, and a second end having at least one fastener configured to mate the second end to a second location on a vertebra. The elongate body also includes a deformable portion extending between the first and second ends that has an unexpanded configuration in which the deformable portion is configured to allow a tool to cut bone extending between the first and second ends when the first and second ends are mated to first and second locations on a vertebra, and an expanded configuration in which the deformable portion is deformed to increase a distance between the first and second ends such that a gap is created in the cut bone. The deformable portion is configured to maintain the first and second ends at a fixed distance apart when the deformable portion is in the expanded configuration. A vertebral implant is also provided that includes an elongate member configured to extend into a vertebra and form a hinge therein using a breakage point located along a length of the elongate member.
