Method of providing a threaded bore in a prosthetic implant

摘要

A method to form a blind bore in an implant wherein a bore is initially drilled through the articular surface of the posterior condyle. The bore is internally threaded and then a plug is welded in place to seal the opening of the bore from the articular surface. The weld bead is polished so that there is no interruption in the articular surface. By drilling and threading the bore from the articular surface, there is no restriction on space, and automated machining equipment can be readily used.
