All-metal hip replacements have been in the spotlight recently due to thousands of lawsuits filed against manufacturers of these products. Lawsuits allege the implants are linked to serious medical complications, including metal poisoning and bone deterioration. Plaintiffs in lawsuits against Johnson & Johnson for its DePuy Pinnacle hip replacement claim they suffered from metal poisoning and other complications after the implant shed metal, affecting surrounding tissue. Despite these risks, J&J has not issued a recall for its all-metal hip replacements.
Medical Complications Linked to DePuy Pinnacle Hip Implants
All-metal hip implants pose the risk of several serious medical conditions, including:
- Severe pain
- Dislocation
- Deterioration of surrounding bone
- Death of surrounding tissue
- Implant loosening
- Inflammation and swelling
- Infection
- The need for revision surgery
- Metallosis (a type of metal poisoning)
It was originally believed that all-metal hip replacements would last longer and be more durable than their ceramic or plastic counterparts. However, it appears that the vast majority of complications are linked to the all-metal implants. In fact, many patients report that their all-metal device failed only a few years after being implanted. Research has shown that the issue is likely due to the process of metal shedding that often occurs with these implants. When metal particles are released into the surrounding tissue, high levels of cobalt and chromium may build up in the blood, resulting in a condition called metallosis. This painful, potentially-debilitating condition can lead to death of surrounding tissue, and deterioration of surrounding bone.
Symptoms of a Malfunctioning Hip Implant
According to a report from the National Joint Registry in Great Britain, up to 14 percent of all-metal hip replacements need to be removed within seven years. If you have a hip replacement device, the following symptoms may indicate a malfunction with your implant.
- Severe pain in the hip, leg or groin
- Difficulty walking
- Difficulty standing
- Swelling at or around the hip joint
- Popping, squeaking, or grinding sounds
- Kidney problems
- Skin rashes
- Depression
- Thyroid problems
- An enlarged heart
In 2011, the FDA issued a warning about the potential dangers of metal debris from all-metal hip replacements. The agency said that high levels of cobalt and chromium in the blood may cause additional illnesses and medical complications, including problems with the heart, thyroid, and nervous system.
