Abstract
The invention relates to a device intended to replace or partially replace one or more vertebral bodies or intervertebral discs in the cervical, thoracic or lumbar spine, and includes methods for its use and deployment. The invention may be used to restore biomechanical parameters correlating with improved patient outcomes and also involves a method for a more effective discectomy or corpectomy prior to graft deployment.
Claims16
An apparatus, comprising:
- a first element having a top surface and a bottom surface configured to contact opposing bone surfaces, wherein the top and bottom surfaces each include a surface treatment, wherein the surface treatment reduces migration of the first element after insertion of the first element into a body;
- a second element;
- a first bridging structure in mechanical communication with both the first element and the second element, wherein upon actuation of the bridging structure, the first element and the second element separate from one another;
- and
- a lordotic expander associated with the first element, wherein upon actuation of the lordotic expander, a height of the first element in the rostralcaudal direction increases without increasing a height of the second element in the rostralcaudal direction, and actuation of the lordotic expander does not separate the first element from the second element.

A system for spine surgery, comprising:
- a device including a first element having a top surface and a bottom surface configured to contact opposing bone surfaces, wherein the top and bottom surfaces each include a surface treatment, wherein the surface treatment reduces migration of the first element after insertion of the first element into a body, a second element, a bridging structure in mechanical communication with both the first element and the second element, wherein upon actuation of the bridging structure, the first element and the second element separate from one another, and an expander connected to the first element, wherein upon actuation of the expander, a height of the first element in the rostralcaudal direction increases without increasing a height of the second element in the rostralcaudal direction;
- a bridging tool that interacts with the device to actuate the bridging structure to expand the device in the anterior-posterior direction in the spine;
- and
- an expander tool that interacts with the expander of the device to increase the height of the first element in the rostralcaudal direction to achieve lordosis without increasing the height of the second element in the rostralcaudal direction.
