For optimisation of surface structures of cementless endoprostheses, the bio-mechanical characteristics of a meso-structured tripode were tested under combined shear- and bending force. Theses results were compared to spherical surfaces.
The effect of the shape, size and linkages between tripod-structures was also examined.
The upper part of the tripode-structure showed the least stability. The stability of this area was significantly improved by optimizing the shape and the linkages between the structures . The spherical-structure showed a more refractory fracture behaviour compared with the tripode-surface.
