Langton DJ, Jameson SS, Joyce TJ, Hallab NJ, Natu S, Nargol AVF. Early failure of metal-on-metal bearings in hip resurfacing and large-diameter total hip replacement, A CONSEQUENCE OF EXCESS WEAR. J Bone Joint Surg Br. 2010; 92-B: 38-46
This peer-reviewed article from the January 2010 edition of the Journal for Bone and Joint Surgery discusses the success of the BHR Hip relative to another device. In this study, 155 consecutive BHR Hip patients were tracked, and the author found that none were revised due to metal wear debris. In the same study, the author also tracked 505 metal on metal implants from a different manufacturer and found revision rates of 5.9% and 11.4%, respectively, for two of this company's implant designs.

This study, presented at the 2010 annual meeting of the American Academy of Orthopaedic Surgeons, reinforces what Dr. Edwin Su spoke about at the March 6, 2010, press conference. That is, the success of a hip resurfacing procedure depends on patient and implant selection.
