Metal on Metal Hip Replacements
Alley, Clark & Greiwe continues to aggressively pursue claims on behalf of persons who have suffered serious injury and disability related to metal-on-metal hip implants manufactured by several different companies. Most metal-on-metal hip implants were approved under the FDA’s controversial 510(k) approval process. The 510(k) approval process does not require submission of any clinical trials or safety studies before marketing and distribution occurs across the U.S.
Until just a couple of years ago, more than one-third of all hip replacements performed annually in the U.S. were performed with a metal-on-metal implant configuration. This means the “ball and socket” artificial hip components were made from cobalt-chromium metal alloys. Metal-on-metal hip implants became popular because the metal was thought to be more durable than traditional implants made from ceramic or plastic.
Studies have now shown that metal-on-metal hip implants generate metallic “wear debris” as the weight bearing components rub together during normal movement. The tiny particles of metallic debris can lead to a unique complication called metallosis in some patients. Metallosis is the buildup of metallic debris in the surrounding soft tissues that can cause early implant failure, chronic pain, inflammation, swelling, muscle and tissue damage, pseudo-tumor formation, and high levels of cobalt and chromium in patients’ blood.
Overall, the failure rate of metal-on-metal hip implants has been much higher than traditional implants made of ceramic or polyethylene. In the last few years, thousands of patients across the U.S. have undergone extensive revision surgeries to remove one or more metal hip components. Unfortunately, revision surgeries are often more complicated by joint instability. Joint instability has been reported to occur more frequently in hips that are revised because of tissue damage caused by metallosis.
Since there is no joint registry system in the U.S., it is impossible to calculate with any certainty the exact number of failures of all-metal hips. Some manufacturers’ metal hip products have higher failure rates than other manufacturers.
