Abstract

Aim of this study was to evaluate stem subsidence and survivorship of implant following implantation of Revitan (Zimmer) and MP (Waldemar Link) stems. Retrospective case series with clinical and radiological follow-up of 1-10 years. 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. There is no significant difference in subsidence or survivorship between Revitan and MP stems.
