Abstract
The present invention relates to an intervertebral implant for fusion of vertebrae. The implant has top and bottom surfaces configured and dimensioned to contact end plates of the vertebrae and a jacket forming a side surface of the implant and having a three-dimensional texture for promoting initial stability. The implant is made of a porous ceramic material. The implant according to this invention is characterized in that upon primary fusion during the resorption process, it equalizes the distance (corresponding to intervertebral disk height) between two vertebrae while providing adequate fusion and is resorbed by the body after a certain amount of time.
