Aims: The aim of the present study was to evaluate the 7-year functional outcome and radiographic results of primary total hip arthroplasties (THAs) performed with the uncemented Avenir stem. Patients and methods: Between January 2006 and October 2008, 100 consecutive primary hips in 92 patients were enrolled at 2 centres. The mean age at operation was 58.5 years (27–87 years). Mini-incision (50%) and standard approaches (50%) were used to implant 22 standard and 78 lateralised stems. Results: The 7-year Kaplan-Meier survival rate was 98.9% (95% CI, 92.9–99.8) with stem revision for any reason as endpoint. No stem related complications occurred. 1 stem revision was due to deep infection at 51 months post-op. We had 4 acetabular revisions. The mean Harris Hip Score (HHS) at 7 years follow-up was 93.1 points (60–100). Radiographic analysis showed 2 patients had non-progressive radiolucent lines and no patient had any signs of stem subsidence or loosening. Conclusion: The 7-year implant survival and the functional outcomes for THA performed with the study device are excellent and were in line with those documented for comparable contemporary uncemented fully HA-coated stems. Longer term follow-up of this consecutive series needs to be performed.
