Abstract
Embodiments of the invention include systems and methods for replacing at least a part of a vertebral body. Systems may include end components for interfacing with adjacent vertebrae and a central component for placement between end components. Instruments for placing system components and preparing anatomical structures to receive system embodiments may also be included.
Claims21
A vertebral body replacement system comprising:
- a spreader instrument with a first tip and a second tip, wherein the spreader instrument is operable to move the first tip and the second tip farther apart from one another and closer to one another;
- a first end component having a height, a width, and a depth, wherein the depth is greater than the width, and wherein the first end component is configured to couple with the first tip, and wherein an extent of the height of the first end component is configured to be placed against a first adjacent vertebral body;
- a second end component having a height, a width, and a depth, wherein the depth is greater than the width, and wherein the second end component is configured to couple with the second tip, and wherein an extent of the height of the second end component is configured to be placed against a second adjacent vertebral body;
- and
- at least one central component having a height, a width, and a depth, wherein the depth is greater than the width, and wherein the at least one central component is configured to be placed between the first end component and the second end component.
A method of stabilizing a spine from which a vertebral body will be at least partially removed comprising:
- placing a first end component against a first adjacent vertebral body, including moving the first end component through a space between the first adjacent vertebral body and a nerve root extending from a spinal cord;
- placing a second end component against a second adjacent vertebral body opposite from the first end component;
- and
- inserting a first central component between the first end component and the second end component, including moving the first central component through a space between the second end component and the nerve root extending from the spinal cord.
A method of performing a vertebral body replacement comprising:
- implanting a first end component that includes a first track against a first adjacent vertebral body, wherein the first adjacent vertebral body is on a first side of the vertebral body to be replaced, and wherein the first track is oriented toward the vertebral body to be replaced;
- implanting a second end component that includes a second track against a second adjacent vertebral body, wherein the second adjacent vertebral body is on a second side of the vertebral body to be replaced that is opposite from the first side, and wherein the second track is oriented toward the vertebral body to be replaced;
- and
- moving a first osteotome in the first track and the second track to cut tissue between the first track and the second track.
