CEMENT-FREE INCORPORATION OF ENDOPROTHESE S BY MEANS OF TRABECULAR, 3-DIMENSIONAL INTERCONNECTED SURFACE-STRUCTURES

While the principle of enlarging the surface area has been recognized and used in different ways for some time, there is often no schematic, detailed description or fundamental research. Taking a surface struct ure consisting of trabecular three-dimensional connecting elements, es sential parameters are shown, making it clear that the flexible dynami c reaction of the effective'' anchoring space'' with a suitable specif ied shape (construction height, alignment, network) can be reproducibl y shaped and used. This has led to a hip endoprosthesis with a graduat ed surface structure. The construction height of the trabecular struct ure varies, decreasing from proximal to distal.
