Official title
Serum Metal Ion Concentrations Following Unilateral Versus Bilateral Large Head Metal on Metal Primary Hip Arthroplasty
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The objective of this study is to compare serum chromium and cobalt levels of patients who have undergone metal on metal total hip arthroplasty. It is unknown if the presence of bilateral well-functioning large-head metal-on-metal (MOM) total hip arthroplasties (THAs) leads to higher serum metal ion concentrations than unilateral MOM THA. Elevated levels (chromium, 17 μg/L; cobalt, 19 μg/L) have been associated with poorly functioning MOM THA with metallosis. Fourteen patients having undergone bilateral and 25 patients having undergone unilateral large-head primary MOM THA were compared. Harris Hip Scores, University of California Los Angeles activity scores, radiographs, serum creatinine, and serum cobalt and chromium levels were obtained.
