Metasul Monoblock Component™ Cup in a Hip Resurfacing Application With the Durom® Hip Resurfacing Femoral Component

Analyses was performed pre-operatively, 6 months, 1 year, 2 years and 5 years post-operatively for all study subjects enrolled in this study, as well as, all revision study subjects receiving the Metasul LDH™ total hip system. To prevent intra-observer variation the metal ion concentrations was analysed by an approved Central Laboratory. The Central Laboratory provided specimen collection kits for the transfer of blood specimens to the Laboratory for analysis. The Laboratory provided the results to the Investigators. The cobalt and chromium was measured by induced coupled plasma mass spectrometry (ICP-MS). BUN, creatinine and GFR will be determined locally.
