Osseous prosthetic implant for treating e.g. osteoporosis, has predetermined expansion value adjusting unit with material veil disposed between supports and corresponding plates and having thickness to control expansion of implant

摘要

The implant has an expansion plane (2) intrinsic to the implant, and two opposite plates forming respective bearing areas that move way from each other according to the plane. A set of supports is disposed beneath the respective plates. A predetermined expansion value adjusting unit (5) comprises a material veil disposed between each support and corresponding plate and has a thickness to control expansion of the implant.
