BIOLOX ® Makes the Difference Goals to Achieve The problems created by wear debris in THR bearing systems containing polyethyl­ ne or e metal make reducing wear an imperative. The objective must be to avoid the need for revision while still allowing the patient to live a normal or even high activity lifestyle. Therefore, articulating materials should have: Neocapsule of an autopsy specimen of a patient with ceramicceramic couple after 8 years in vivo show­ng no ceramic i particles, smooth syno­ ial surface and v moderate fibrosis.6 • the lowest production of wear particles • the best biological...

After aseptic loosening, they are the most common reasons for revision surgery.26 The incidence of dislocation following primary THR ranges from roughly 1% and 5% and for revision surgery it can be as high as 10%.22, 28 Many everyday acti­ vities require strong flexion or abduction of the hip joint. In a conventional artificial hip these move­ments may cause impingement...

Particle Problem Material Answers Large Diameters Wear Couples Large Diameters: Advantages and Disadvantages of Different Materials The advantages of ceramic materials in wear couples become even more evident with large diameters. Hip joint simulator studies show that even though the sur­ faces exposed to friction are much bigger, the wear rates remain very low and are significantly lower than with other materials. With the use of ceramics the surgeon doesn’t have to compromise between wear rate and head size and can choose the best option for the patient. Hip Joint Simulator – Highly Crosslinked...

Ceramic-on-ceramic bearings with large diameters combine all of the advantages of today’s tribological technology. Their biological and biomechanical properties help to spare natural anatomy and physiology to the greatest possible extent. Drastically reduced wear, a large range of motion as well as additional resistance to dislocation make these bearings the ideal choice for safety and longevity in total hip replacement. In contrast to polyethylene and crosslinked polyethylene wear couples, the wear rate of ceramic-on-ceramic couples does not rise with increased head size.1 Fig. 7: Retrieval...
