The present invention provides an intervertebral fusion apparatus for positioning and combining vertebrae, which use a solidifiable material and an intervertebral fusion cage concurrently. By diffusing the solidifiable material from the top or bottom surface of the intervertebral fusion cage, the contact area with vertebrae and hence the stability can be increased. In addition, the intervertebral fusion cage provided by the present invention can further include a wing member connected pivotally on the side and operated concurrently with the solidifiable material to change the shape and thus avoid slipping off the operation opening. By using the intervertebral fusion apparatus, the stability of the intervertebral fusion cage during and after surgeries can be improved effectively. Thereby, the success rate and safety of vertebral fusion surgeries can be increased.
