Since 2004, the reamers are in daily clinical use. Surgeons comment was: The reamed surface was extremely precise and smooth, achieving a reamed space that was, in effect, exactly matching the reamer size.
In Clinic Garmisch-Partenkirchen one set of these reamers was used in over 400 hip replacement surgeries (2004-2006). FEM Studies (1999-2002) of cup stability conclude that the highest stability was shown where the discrepancy was 0.25mm. More or less led to instability and increase the potential for wear particles between cup and bone.
Recent studies (2009) suggest that pelvic underreaming where thin shells are employed may be contributory to early damage/disassociation of modular, acetabular components. Conclusion: an accurate ca
