Full Text: Dear Editor:

We read with great interest the article by O'Neill and colleagues on the "Canadian Academic Experience with Metal-On-Metal Hip Resurfacing." (1) The article was informative and well written. We did notice, however, that our article evaluating the early U.S. experience with Birmingham hip resurfacing (2) following FDA approval was misquoted through no fault of the authors. The version of our abstract that was available when the article was written erroneously reported the 1-year revision rate at 7.4%, when the actual revision rate was 3.1% (14 of the 449 cases with 1-year follow-up). This error was not realized until after our work was available online as an electronic publication. Using this uncorrected version of our work simply repeated this error. The abstract of our findings available in PubMed has now been corrected. Additionally, a letter to the editor in the February 2009 issue of Clinical Orthopaedics and Related Research corrected the error as well. (3) We point this out so that the readers of the Bulletin have a clearer understanding of the data that has been reported.

We thank Drs. Della Valle and Barrack for their letter which accurately reflects the reason that 7.4% was misquoted.
