Guest guest Posted January 31, 2003 Report Share Posted January 31, 2003 The following is from the finsbury web page and I am pretty sure they as all manufacturers have a financial interest in the success of the implant. That being said.. I have seen data that is from an opposing manufacturer that supports the statements on production differences. Most of the rest you can find at Midlands page as well. Oh and I know of no beer that cost as much to age and brew as Budweiser _____________________________________________________________________ The " Birmingham Hip Resurfacing " (BHR) is the result of a unique joint collaboration and development of technologies between surgeons, Midland Medical Technologies (MMT Ltd), Doncasters Centaur Precision Castings and Finsbury. Development of the manufacturing techniques has allowed Finsbury to produce the BHR to new levels of precision in metal-on-metal technology. The production of all types of heads and cups by other manufacturers has now been seen to have considerable variation of sphericity, surface finish, clearance and metallurgy: factors that exacerbate the phenomena of `running in' and wear rate. The development of the BHR has shown that by obtaining high quality castings that do not require heat treatments to rectify defects and improve their properties, a metallurgy with a harder, longer-wearing surface can be produced - but not without increased production difficulty. To reduce the wear of metal-on-metal resurfacing to that of the best clinical long term Ring hip results (less than 2 microns of linear wear per year) is possible, but at a cost. Thus, the successful development of a manufacturing process for the Birmingham Hip Resurfacing has brought advantages to this implant's function and its long term potential. This unique manufacturing technology has been particularly important for a large head and cup, metal-on-metal implant like the BHR, for which very low sphericity and surface finish can now be shown to generate considerable levels of fluid film lubrication. This undoubtedly contributes to the remarkable performance, and more natural patient feel, that results from the BHR manufactured by Finsbury for Midland Medical Technologies Ltd. ----------------------------------------------------------------- Tho Quote Link to comment Share on other sites More sharing options...
