A visco-elastic facet joint implant for insertion into a facet joint between an inferior facet formed on a superior vertebral body and a superior facet formed on an inferior vertebral body. The facet implant includes a visco-elastic implant element molded into an anatomically fitted shape to optimally fit between the facet joint and one or more bone fixation elements to secure the visco-elastic implant element to the superior and/or inferior vertebral bodies. In use, the visco-elastic facet joint implant includes a first end for engaging the superior vertebral body, a middle portion for passing through the facet joint and an optional second end for engaging the inferior vertebral body.

Visco-elastic facet joint implant

A flexible dampening intervertebral spacer () to replace a spinal disc comprising upper and lower plates (), an articulation element () and optional intermediate members (). The articulation element has a plurality of interposed, concentric ring shaped segments () separated by one or more spaces () and one or more bridging elements () connecting the interposed segments. A first portion of the articulation element, preferably an innermost segment, is preferably fixedly connected to the upper plate while a second portion of the articulation element, preferably the outermost segment, is preferably connected to the lower plate to permit relative movement of the endplates by elastic deflection or flexing of the articulation element without opposed surfaces rubbing against each other.

Flexible dampening intervertebral spacer device

A flexible element that may be configured, among various uses, as an intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The flexible element includes one or more struts extending from superior and inferior endplates and bending towards one another for connection with one or more internal beams.
