Joseph Conrad and Popular Cultureramic heads were reported. This resulted in the introduction of zirconia (yttriastabilised tetragonal zirconia, Y-TZP) as a ceramic femoral head, with its improved strength and fracture toughness. Zirconia, however, is known to undergo hydrothermal degradation. This hydrothermal degradation is due t

The preoperative diagnosis in all cases was osteoarthritis. The mean linear wear rate of polyethylene sockets against zirconia heads were 0.133 mm/

Conclusion: Reading Conrad Now,d reduced risk of dislocations. Larger diameter hard on hard bearings may as well change the wear characteristics due to larger wear areas or different lubrication behaviour from changed diameter tolerances as known from Me-Me large bearings. But not only hard-on-hard bearings are of interest. With

Conclusion: Subverting the Imperial Romance,dwide in 2006. Long-term studies of selected patient cohorts [.,.,.] and hip registries in Sweden and Norway have demonstrated good survivorship rates up to ten years followed by a significant drop during the second decade. To date, younger and more active patients who have longer life expectancies
