Abstract
An interbody spinal implant including a body and an integration plate having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, and a substantially hollow center in communication with a vertical aperture. The body is recessed in a way that portions of the integration plate protrude above the top and/or bottom surface of the body to enhance the resistance of the implant to expulsion from the intervertebral space.
Claims29
An interbody spinal implant, comprising:
- a body that is generally oval-shaped in transverse cross section, and comprises a top surface, a bottom surface, a posterior portion, an anterior portion comprising a solid rear wall extending substantially the entire width and height of the body, a substantially hollow center, and a single vertical aperture extending from the top surface to the bottom surface, and having varying width and maximum width at its center, wherein a portion of the top surface of the body, is recessed and comprises a plurality of vertical holes along the periphery of the vertical aperture, and wherein the recessed portion of the top surface of the body has an anterior section corresponding the anterior portion of the body and a posterior section corresponding to the posterior portion of the body;
- a first integration plate comprising a top surface having a roughened surface topography adapted to grip bone and inhibit migration of the implant, a bottom surface having a plurality of vertical posts, opposing lateral sides, opposing anterior and posterior portions, and a single vertical aperture extending from the top surface to the bottom surface of the integration plate, aligning with the single vertical aperture of the body, and defining a transverse rim,
- wherein the entire bottom surface of the first integration plate is inserted into the recessed portion of the top surface of the body and the plurality of posts are inserted into the plurality of holes, thereby affixing the first integration plate to the body;
- and
- optionally a second integration plate comprising a top surface having a roughened surface topography adapted to grip bone and inhibit migration of the implant, a bottom surface having a plurality of vertical posts, opposing lateral sides, opposing anterior and posterior portions, and a single vertical aperture extending from the top surface to the bottom surface of the integration plate, aligning with the single vertical aperture of the body, and defining a transverse rim,
- wherein if the second integration plate is present, a portion of the bottom surface of the body is recessed and comprises a plurality of vertical holes along the periphery of the vertical aperture, the non-recessed portion of the bottom surface comprises a blunt and radiused portion, wherein the recessed portion of the bottom surface of the body has an anterior section corresponding the anterior portion of the body and a posterior section corresponding to the posterior portion of the body,
- and wherein the entire bottom surface of the second integration plate is inserted into the recessed portion of the bottom surface of the body and the plurality of posts are inserted into the plurality of holes, thereby affixing the second integration plate to the body.
