Article: Method of giving porous surface to implants proves cheaper.

Providing an orthpaedic implant with a porous surface layer using existing technologies is both time consuming and expensive for the implant manufacturer.

Scientists based in the USA have developed a method of creating the porous surface using a process that involves an organic binder compound. (See US patent 6 132 674).

The porous surface is useful in promoting bone ingrowth and helping implant fixation within the bone. Bone cement can also be used on the porous surface to improve implant fixation.

Current methods of constructing the porous surface involve using metal beads or metal fibres which are sintered, diffusion bonded, or welded to the ...
