Abstract
A spinal implant having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions. At least one of the top surface and bottom surface has a roughened surface topography, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction generated when the implant is placed between two vertebrae and to inhibit migration of the implant. At least one of the top surface and the bottom surface also includes at least one self-deploying anchor having an expulsion tab and a bone-engaging tip that causes the implant to resist expulsion once the expulsion tab is deployed.
