The longevity of the hip devices had already been debated several times over the past few years. Moreover, one company issued a product recall just last year. Also, the manufacturers were ordered by United States regulators to conduct more studies regarding safety of the devices.
Every year, hip implant patients are advised by the UK Medicines and Healthcare products Regulatory Agency to undergo yearly blood tests. This is to make certain no hazardous metal fragments are present in the systems of these patients. The patients who experience symptoms, such as inflammation, pain, and encumbered movements, are also informed to get an MRI scan.
In a recent study, more than a hundred thousand hip implants from the National Joint Registry of England and Wales were analyzed by experts. The experts found out that over 30,000 of the hip systems were all-metal.
The study showed that six percent of the implant patients who had metal on metal systems were in need of revision surgery after five years. In contrast, only 1-2% of implant patients who had ceramic or plastic systems needed correction surgery. Physicians anticipate hip implants to last at least 10 years. This study was published in a journal called Lancet. It was funded by the National Joint Registry.
Failure Rates Of The Implant
The leader of orthopaedic research at the University in Bristol, Ashley Blom, stated that most people with all-metal hip implants have not needed revision surgery. However, he stated that the implants were not worth the risks. He said, €If I were a patient, I would not choose a metal-on-metal hip.€ Moreover, he stated that many patients did not report their symptoms and kept quiet about their failed hip implants. Therefore, the reported failure rate of all-metal hips were most likely underestimated.
Depuy Orthopaedics, a subsidiary of Johnson & Johnson, issued a recall of its metal-on-metal hip system in 2010 due to the implant's high failure rate. According to Blom, the problems of these hip systems persisted in all brands of the hip devices.
Ever since lab tests suggested that the devices were durable and less prone to dislocation, medical experts started utilizing all-metal hip systems. However, after a few years since its debut, the hip systems were still not performing as well as it should have. Just last year, the FDA ordered every metal-on-metal hip manufacturer to conduct safety studies. Recently, the usage of hip systems have dropped by a large margin. Moreover, the number of hip replacement lawsuits have increased.
Personal injury law firms have assisted several patients in acquiring compensation. These law firms have put up websites, such as the Rottenstein Law Group's rotlaw.com, to share updates and information regarding lawsuits against hip replacement manufacturers.
