DeclarationB.O. has received funding from Zimmer Inc. to partially cover costs of attending a conference to present the results of this study. IntroductionPatient use of the internet for information on health continues to grow.1,2 Such information can influence the patient/physician relationship, 3 and can also lead to patient harm. 4 Direct to Consumer Advertising (DCTA) via the internet continues to increase in importance. 5,6 DCTA can put pressure on health care professionals to provide specific treatments not currently available, or which are expensive. The aim of this advertising is to persuade the patient to use the product and criticisms of this type of advertising includes poor explanation of risks, outcomes etc. In addition, the quality of the information of this website is not often accredited by organisations such as HON (Health on the Net). Whilst such advertising is not permitted in the United Kingdom (UK), access to internet sites outwith the UK is still likely to influence patients as research suggests that patients are not influenced by country of origin of websites, even when the information they seek may be very country specific. 7Of particular interest is the recent trend towards increased use of DTCA in orthopaedic implants/devices. 8 Whilst a number of studies have looked at the quality of health related information on the web, this has been directed towards disease where our knowledge is relatively well established. Hip resurfacing is an evolving technology 9,10,11 and as such generates much discussion on the web. Further, it is an operation advocated for young patients 9,10,12 who are the most likely to seek health information on the Internet.3 It was the aim of this study to identify a method for measuring quality of health information on the Internet and to use this to identify the quality of hip resurfacing websites. Method Websites with Hip Resurfacing InformationThe top six internet search engines (Yahoo, MSN, Google, AOL, Ask Jeeves and Lycos) 13 were used to identify websites containing information about hip resurfacing. We used the following key terms "hip resurfacing", "hip surface replacement" and "Birmingham hip". People are most likely to visit the first 10 results generated by a search page 7,14 and as such the first page of each search engine result (containing 10 website links) was assessed. Sponsored links on the first page were also assessed. As Google is the largest and most widely used search engine, 13 the first two pages of results generated were assessed. Websites were excluded if they were; duplicated, Abstract Background and Aims

Heterotopic Bone Formation following Resurfacing Total Hip Arthroplasty

Heterotopic bone (HO), a rare association with total hip arthroplasty (THA), has recently been shown to be more of a problem with resurfacing hip arthroplasty (RHA). It has been speculated to be the result of greater soft tissue dissection required for this procedure. HO most commonly develops in males and patients with bilateral disease. To better understand if this problem does occur in RHA, groups of patients with RHA on one side and conventional THA on the other were evaluated. We retrospectively identified 45 patients that had RHA on one side and conventional cemented THA on the other. Follow-up has been up to 25 years. HO was graded at every clinical visit using the Brooker Classification. In the RHA group, there were 32 hips without evidence of HO, ten with grade 1, and three with grades 2 or 3. In the THA group, there were 36 hips without any HO, eight with grade 1, and one with grade 2. There was no statistical difference between either types of hip arthroplasty in HO formation overall or in the development of more severe grades. Motion was not significantly affected with the more severe grades. Our data obtained from a bilateral patient model suggests that RHA does not predispose to a greater development of HO. In doing a RHA, one should be aware that there might be an increased likelihood of HO in males with bilateral disease.

“…The acetabulum and femoral head were prepared using the recommended technique with each system. articulation (Zimmer, Inc) has been used since 1988 [29,61]. The postoperative protocol was the same throughout the study, which included prophylactic antibiotics for 24 hours and low-molecular-weight heparin for 10 days.…”
