Stainless steel threaded sleeves are key components of the bone cement syringes that are used for hip replacement implants. To optimise the manufacture of these sleeves, Moller Medical opted for deep-hole drills from Walter. Drilling the sleeves led to better results than when bright-drawn tubes were used. Nowadays, hip replacement implantations are routine procedures in the operating theatre. However, with patients becoming older and older, surgeons are increasingly having to deal with already weakened bone structures - many patients suffer from osteoporosis. Nonetheless, a robust bone substance is required to ensure that the implants can be firmly held in place. The medical profession has long known about the method of using bone cement to stabilise weakened bone substance in osteoporosis patients. If the implants are not sufficiently stable, there is the option to stabilise the bones using a special cement comparable with Plexiglas (PMMA). Without this technique, it would not be possible to insert joint implants for patients and for them to regain their mobility.
