As Biomet Hip Lawsuits Mount, Bernstein Liebhard LLP Notes New Study Investigating Cancer Risks in Metal-on-Metal Hip Implant Patients

Bernstein Liebhard LLP notes the publication of a new study investigating cancer risks in metal-on-metal hip implant patients. The study, which was published in the February 2014 issue of Acta Orthopaedica, compared data from the Finnish Arthroplasty Register involving 10,728 patients with metal-on-metal hip implants and 18,235 patients who received other types of hip replacements. Though the findings suggested that all-metal hips were not associated with a higher risk of cancer overall, the data did indicate that metal-on-metal hip implant patients were more likely to develop soft-tissue sarcoma and basalioma. The all-metal hip patients were followed for an average of 4.6 years, while those with other devices were followed for an average of 6 years.*

While the authors of the study concluded that metal-on-metal hip implants were not associated with an overall increased risk of cancer, they did caution that such devices should not be considered safe until data with longer follow-up time are available.
