Hip replacement failures are more common than previously believed, especially in metal on metal hip replacement joint devices.
At least 500,000 Americans have had hip replacement surgery, and many have metal on metal (MoM) implants manufactured by companies like Johnson & Johnson, Stryker, Wright Medical Technology, Biomet and other manufacturers, in which hip replacement failure is more common that previously thought.
If you or someone you know are experiencing some of the hip replacement complications listed below, or if you already had your metal on metal hip implant replaced because of similar problems, the injuredGo.com law firm would be happy to discuss your situation to determine if you are due compensation for your injuries.
- Failure of the metal on metal hip implant requiring early replacement
- Dislocated hip
- Leaking of toxic substances in your bloodstream from your hip implants like chromium or cobalt
- Degenerative Heart Disease or Cardiomyopathy
- Loss of bone strength or structure which can result in bone fractures
- Tissue death for any tissue surrounding the implant
- Non-cancerous tumors or pseudotumors around the hip implant
- Cobalt poisoning
- Metallosis or metal poisoning due to chromium or cobalt particles from the hip implant leaking into nearby tissue or the patient’s bloodstream
According to the FDA, “in MoM hip implants, the metal ball and the metal cup slide against each other during walking or running. Metal can also be released from other parts of the implant where two implant components connect. Metal release will cause some tiny metal particles to wear off of the device into the space around the implant. Wear and corrosion at the connection between the metal ball and taper of the stem may also occur. Some of the metal ions (e.g. cobalt and chromium) from the metal implant or from the metal particles will enter the bloodstream.”
Furthermore, “Patients who receive MoM hip implants should also pay close attention to changes in their general health including new or worsening symptoms outside their hip. If they are referred to a doctor to evaluate new conditions, they should let their physician know they have a MoM hip implant. There have been some case reports and articles in the medical literature that suggest patients with a MoM hip implant may have certain symptoms or illnesses elsewhere in the body (systemic reactions). These include:
- General hypersensitivity reaction (skin rash)
- Neurological changes including sensory changes (auditory, or visual impairments)
- Psychological status change (including depression or cognitive impairment)
- Renal function impairment
- Thyroid dysfunction (including neck discomfort, fatigue, weight gain or feeling cold.”
