Joint endoprosthesis |
摘要 |
The joint endoprosthesis is formed of a compressible elastic hollow body which is disposed between two anchoring elements. The hollow body defines a closed cavity which is filled with an incompressible fluid medium. Compressive loadings near the edges of the endoprosthesis cause a displacement of the liquid into relieved regions of the prosthesis so as to avoid tensile forces from occurring in the anchoring of the prosthesis to the bones.
