Patent number: 10034764Abstract: A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The second piece can be configured to include lips that abut the apothyseal rings during, with the plate including bores angled such that fasteners penetrate the apothyseal rings.Type: GrantFiled: April 27, 2012Date of Patent: July 31, 2018Assignee: SpineSmith Partners, L.P.Inventors: Richard Kana, Kevin Dunworth, Luis Duarte, Brian Burkinshaw, Mukund Gundanna, Ryan Medema
