A small percentage (<1%) of patients have developed an inflammatory response, and a more severe inflammatory response termed pseudotumor has been more recently reported. The primary purpose of this study was to determine the prevalence of pseudotumor following metal-on-metal hip resurfacing in Canadian academic centers.
Nine of the fourteen centers that perform metal-on-metal hip resurfacings were surveyed. The number of metal-on-metal hip resurfacing arthroplasties performed at each center was determined, as was the number of patients who presented with a pseudotumor and subsequently required revision hip surgery between 2002 and December 2008.
At the nine centers, 3432 hip resurfacing arthroplasties were performed; 76.9% of the patients were male, the mean age was 51.2 years (range, sixteen to eighty-three years), and the mean body-mass index was 28.1 (range, 17 to 55). The mean length of follow-up was 3.4 years (range, two to nine years). A pseudotumor developed after four of the 3432 arthroplasties, for a prevalence of 0.10%.
Although pseudotumors remain a concern after metal-on-metal hip resurfacing, the prevalence at short to midterm follow-up is very low in this multicenter survey. Continued close monitoring is required to determine what clinical factors are involved with the uncommon pseudotumor formation.</description><identifier>ISSN: 0021-9355</identifier><identifier>EISSN: 1535-1386</identifier><identifier>DOI: 10.2106/JBJS.J.01848</identifier><identifier>PMID: 21543700</identifier><identifier>CODEN: JBJSA3</identifier><language>eng</language><publisher>Boston, MA: The Journal of Bone and Joint Surgery, Inc</publisher><subject>Adolescent ; Adult ; Aged ; Aged, 80 and over ; Arthroplasty, Replacement, Hip - adverse effects ; Biological and medical sciences ; Canada - epidemiology ; Diseases of the osteoarticular system ; Female ; Follow-Up Studies ; Foreign-Body Reaction - epidemiology ; Foreign-Body Reaction - surgery ; Granuloma, Plasma Cell - epidemiology ; Granuloma, Plasma Cell - surgery ; Hip Prosthesis - adverse effects ; Humans ; Male ; Medical sciences ; Metals ; Middle Aged ; Orthopedic surgery ; Prevalence ; Reoperation ; Surface Properties ; Surgery (general aspects).
