IMPLANTABLE ORTHOPEDIC PROSTHESIS HAVING TISSUE ATTACHMENT SURFACE AND METHOD OF MANUFACTURE |
摘要 |
An implantable orthopedic prosthesis (10) has a macro/micro-textured bone and soft tissue attachment surface (34) to which a spiked washer (40) is clamped by a threaded bolt (46) received through said washer and threaded into said prosthesis. Soft tissue is secured to the prosthesis by clamping between said washer and said soft tissue attachment surface. The tissue attachment surface is arranged as a regular grid of depressions (36) separated by orthogonal ridges (38) formed by electrodischarge machining of the prosthesis using a machining electrode (56) having a mold-opposite surface texture with a micro-textured roughened surface finish. The spacing of the spikes is an integer multiple of the spacing of the depressions to assure registry of the spikes with the depressions. |
