Abstract

Systems, methods and devices for providing stabilization between first and second vertebrae are provided. More particularly, in one form a system includes an implant configured to be positioned in a disc space between the first and second vertebrae and a freestanding plate for engagement with extradiscal surfaces of the first and second vertebrae. The system also includes an insertion instrument with an engaging portion configured to releasably engage with the implant and the plate such that the implant and plate can be positioned together relative to the first and second vertebrae. In one aspect, an angular orientation of the implant relative to the plate is adjustable when the implant and the plate are engaged by the instrument. In this or another aspect, the implant and plate are held in a contiguous relationship when engaged by the instrument. However, different forms and applications are also envisioned.
