Abstract:
:Metasul metal-on-metal articulations have been used for 15 years in approximately 300,000 total hip replacements. We have used Metasul articulations in three clinical studies and have shown clinical success as measured by Harris hip scores and patient self-assessment; we also have had the usual mechanical complications. The only complications have been mechanical, including two cup loosenings and 24 dislocations in a total of 582 patients (619 hips; 3.8%) who had Metasul articulations and were included in these studies. In the randomized study, the group who had Metasul articulations had no clinical results or complications different from the control ceramic-on-polyethylene group. Authors of retrieval results in the literature report low annual linear wear rates and no consequences of elevated Co ion levels. Currently, the scientific evidence of the results of using the Metasul articulation would recommend its continued use in any patient who does not have compromised renal function.
