Devices and Methods for Correcting Vertebral Misalignment

A method of correcting vertebral misalignment, the method comprising:

• accessing adjacent vertebral bodies via an anterior-only approach;
• removing a native disc from in between the adjacent vertebral bodies to form an interbody disc space;
• roughening one or more surfaces of one or both of the adjacent vertebral bodies;
• positioning an implantable assembly within the interbody disc space, wherein the implantable assembly comprises:
• a frame member including a substantially cylindrical central portion, wherein the frame member is configured to be secured to a first vertebral body of the adjacent vertebral bodies by a first fastener;
• a reducing member movably secured to the frame member, wherein the reducing member is configured to be slidably received over the cylindrical central portion, and wherein the reducing member is configured to be secured to a second vertebral body of the adjacent vertebral bodies by a second fastener;
• and
• an actuator for controlling a position of the reducing member relative to the frame member;
• and
• adjusting a position of one of the adjacent vertebral bodies relative to the other of the adjacent vertebral bodies.

A method of aligning vertebral bodies comprising the steps of:

• positioning an vertebral implant between a first and second vertebral body, the vertebral implant comprises:
• a frame assembly having a left lateral portion, a central portion, and a right lateral portion, the left lateral portion and the right lateral portion having an anterior surface for receiving a first and second fastener for securing the frame assembly to the first vertebral body;
• and
• a reducing member configured to be slidably received over the central portion, the reducing member having an anterior surface for receiving a third and fourth fastener for securing the reducing member to the second vertebral body.
• actuating the reducing member to align the first and second vertebral bodies;
• and
• securing the vertebral implant to the first and second vertebral bodies.
