Spinal fusion is surgery to join vertebrae into one single structure. When the disk has been cleared out, surgeon implant a cage between the two adjoining vertebrae. This cage usually contains autograft. Autograft is associated with several disadvantages. We designed a cagea BMP-2 bone substitutes delivery device. The BMP-2 bone substitutes delivery device can transfer more BMP-2 bone substitutes to cageprevent to release the BMP-2 to contact nervemuscle.

The BMP-2 bone substitutes delivery device can transfer more BMP-2 bone substitutes (quintuple of traditional surgery) to cagereduce the operation time.  By this device, the area of filling BMP-2 bone graft in the disc is more than 75.
