BONE IMPLANT, IN PARTICULAR, AN INTER-VERTEBRAL IMPLANT

摘要

The inter-vertebral implant is made from a radiation-transparent material an d embodied as an annular hollow body (1). Said implant comprises a sleeve (6) in the form of a hollow cylindrical section, comprising a front (9), a rear (10 ) and two lateral sections (11) and defines a cylindrical axis (7). The hollow body (1) is divided by two intermediate walls (3), running essentially parallel to the cylinder axis (7) and connecting the front section (9) with the rear section (10) of the sleeve. The surface (2) of the bone implant comprises a surface roughness of at least 2 .mu.m. This surface roughness permits the newly growing bone a better fixation to the implant, in other words a better bone integration.
