1. An intervertebral fusion device, comprising:
- a load-bearing polymeric body having an upper surface and a lower surface and defining an area external to the body for receiving bone graft,an upper metallic component comprising titanium disposed above the upper surface of the body and adapted to prevent excessive movement after implantation,a lower metallic component comprising titanium disposed below the lower surface of the body and adapted to prevent excessive movement after implantation, andbone graft disposed within the area defined by the body,wherein the upper and lower metallic components comprise teeth on bone-facing surfaces thereof.

Abstract
An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.
