The spinal fusion device ( 100 ) of the invention is implanted within an intervertebral space between adjacent upper and lower vertebrae and secured to the vertebrae with cement. The fusion device includes upper and lower endplate facing surfaces ( 150, 160 ) each having at least one opening ( 120 ) for delivering cement material to adjacent contact surfaces of the vertebrae above and below the implant. Utilizing quick-setting cement compositions with the device <:an allow for almost immediate fusion of the vertebrae, thus, reducing or eliminating the need for adjuvant fixation devices such as screws, plates, and/or rods, while also simultaneously providing precise delivery of cement to contact surfaces between the fusion device and vertebrae. |
