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.
