Abstract
BACKGROUND: Aim of this study was to evaluate stem subsidence and survivorship of implant following implantation of Revitan (Zimmer) and MP (Waldemar Link) stems. METHODS: Retrospective case series with clinical and radiological follow-up of 1-10 years. RESULTS: 47 Revitan and 57 MP stems were analyzed. In 12 cases there was subsidence of the stem present. Two Revitan stems and one MP stem were revised as a result of subsidence. Failure rate was 4.3% for Revitan, 1.8% for MP stem and difference was not statistically significant. CONCLUSION: There is no significant difference in subsidence or survivorship between Revitan and MP stems.
