STENOTIC DEVICE

摘要

A spinal implant (50) is configured to be received between bony spinal protrusions of adjacent vertebrae. The spinal implant (50) may be used interlaminar, interbody or interbony protrusion. The present bony spinal protrusion spacer (50) is not fixed to any bony structures of the vertebrae and, as such, use of the present bony spinal protrusion spacer (50) does not result in fusion. It may therefore be removed if necessary. Attachment structures (70) formed as part of the bony spinal protrusion spacer (50) receive and engage portions of adjacent bony protrusions. In this manner, appropriate and/or desired spacing between adjacent vertebrae is maintained: As such, the present bony spinal protrusion spacer (50) is designed to remain safely and permanently in place without attaching to the bone or ligaments of the back.
