摘要： A hollow cylindrical intervertebral implant with a longitudinal axis (3), a covering surface (1) and a base surface (2), made essentially of a ceramic material presenting a maximum porosity of 30 vol. % and which pores are filled with air. The inventive implant is distinguished by the fact that it compensates the distance (corresponding to intervertebral disk height) - after successful primary fusion - between both vertebral bodies during the absorption process - upon adequate fusion - and is resorbed by said bodies after a certain amount of time.
