Publication number: 20170319354Abstract: Various embodiments of intervertebral arthrodesis devices for insertion in an intervertebral space separating opposite faces of two adjacent vertebrae are disclosed. In one embodiment, the device has a ring shaped intervertebral cage having a bar that extends perpendicular to the axis of the spine, the bar has a height less than the rest of the cage, and a surface of the cage contacting the vertebrae has an undulating shape for limiting sliding of the cage in a plane parallel to the vertebrae faces.Type: ApplicationFiled: May 16, 2017Publication date: November 9, 2017Inventors: Christian Louis, Jean Huppert, Patrick Tropiano, Thierry Dufour
