Abstract

The spinal implant described in the present disclosure utilizes an augmented expanding system to build the desired height spacer in-situ without the need for mechanically expanding devices. An expanding spacer system includes a plurality of implant components configured to mate with each other in the intervertebral disc space and a positioning system used to insert each of the plurality of implant components. Each implant component has a smaller dimension and a larger dimension. The positioning system is used to insert the first component into the disc space with the smaller dimension parallel to the spinal axis, and the positioning system is then used to rotate the first implant component to distract the disc space. Additional implant components are added and rotated to further distract the disc space until a desired height is reached.
