Hip Replacement Implants
Defective Metal-on-Metal Hip Replacement Implant Lawyers for New York and New Jersey
Hip implant devices were created with the intention to give people with painful and impaired hip function better mobility for a longer period of time. Traditional hip replacement implants were constructed of ceramic or plastic but over time, they needed to be replaced. Newer all-metal hip replacement systems were meant to be stronger and last longer. But metal-on-metal implants been proven to have a number of unexpected and severe side effects and experience a much higher failure rate than other types of implants. Several models of metal-on-metal hip replacements have been recalled by regulating agencies and manufacturers, and Great Britain’s National Health Service has recently announced a ban on metal-on-metal hip implants.
Metal-on-metal hip replacements have an unusually high failure rate, and that failure rate increases the longer that the hip remains implanted: in a study of one device manufactured by DePuy, the failure rate in patients hit 43% after 9 years. Hip replacement complications including severe pain, inflammation, dead tissue and bone loss often forces patients to have a procedure to replace the implant, known as hip revision surgery. Several companies have manufactured metal-on-metal hip implants that have proven to be defective. There is a long list of reported hip replacement products, but here is a list of the most commonly reported implant devices:
- Depuy Orthopaedics ASR XL Acetabular System
- ASR Hip Resurfacing System
- Wright Medical Technology Conserve Plus
- Zimmer Holdings Durom Cup
- Stryker Orthopaedics Rejuvenate
- ABG II modular-neck hip stems
- Biomet M2a metal-on-metal hip devices
What Problems are Caused by Metal-on-Metal Hip Replacement Implants
Metal-on-metal hip replacements were introduced because it was thought that that they would be stronger and more durable than other types of implants. However, because of the movement of the hip’s ball-and-socket joint, the metal in all-metal hip implant device can wear down and metal debris – usually chromium or cobalt – can flake off and enter surrounding tissue and the blood stream. The metal debris can destroy the tissue around the artificial hip, which can cause the implant to loosen and fail. It is likely that people who have received a defective implant device will initially suffer pain, swelling, inflammation and infection from damage to surrounding bone and tissue. Additional hip revision surgery to remove the defective implant and replace it with a traditional ceramic component artificial hip will be required to correct the problems.
In addition, metal-on-metal hip implant systems can cause metallosis in some patients.
What is Metallosis?
When very small metal particles rub off of the metal joint they can enter the bloodstream and cause metallosis, a type of metal poisoning that occurs when metal ions get into the bloodstream. Besides causing the general failure of the hip implant and requiring additional hip revision surgery, metallosis can cause serious complications affecting the nervous system, skin and other organs in the body.
Symptoms of Metallosis
A study found that the symptoms of metallosis usually change over several months and that they are present within the first four years after the implant surgery. Symptoms of metallosis include:
- Cardiomyopathy, including heart failure
- Psychological changes – depression, anxiety, and other mental changes
- Cognitive impairment
- Nerve problems
- Visual impairment that could lead to blindness
- Hearing impairment that could lead to deafness
- Thyroid problems
- Skin rashes
- Loosening of the implant
- Noise coming from the hip
It is important to know that the risk and symptoms of metallosis may vary by individual, because each person can react very differently to high levels of cobalt. Tissue or bone death, called necrosis, is one of the most common symptoms of metallosis. With necrosis, the tissue around the implant turns gray or black from the metal debris flaking off the implant. This weakening causes pain and instability, which can lead to spontaneous dislocation of the joint, bone loss and fracture.
