Dangers Of Adverse Local Tissue Reaction In MoM Patients

The number of news of hip implant failure have been piling up, health care providers and patients are worried of the effects of metal wear particles on the tissues surrounding the implant. Several news of severe osteolysis and implant failure has been connected with the wear of all-metal hip implants, according to a study published in the National Center for Biotechnology Information. Most patients do not have symptoms, health experts say, they still need to be aware that they need to have a regular follow-up. Several orthopedic experts believe that there might be some people who are having severe complications from their metal hip implant but are not yet aware of the danger.

 

Although all types of implant have their own sets of risks, the Metal-on-Metal hip implant remains to have unique risks on top of all the other risks present in other types of implants. Metal particles are released as the patient uses the hip implant and eventually the particles will build up in surrounding tissues and is carried by the blood. Health complications were reported by some patients as they have experienced a hypersensitivity reaction to these metal ions. However, some of these health complications are systemic as it spreads to the heart, thyroid and nervous system, according to the American Academy of Orthopaedic Surgeons. The Food and Drug Administration (FDA) continues to monitors the adverse reactions experienced by patients with these implants.

 

The FDA has listed the following adverse events reported by patients with Metal-on-Metal hip devices:

- Cardiomyopathy – disease of the heart muscle.

- Changes in psychological status – developing depression, anxiety and other personality changes.

- General hypersensitivity reaction – skin rash all over the body.

- Thyroid dysfunction – signs of fatigue, weight, feeling cold or neck pain.

- Renal function impairment – developing problems in urination.

- Neurological changes – changes in sensory functions like visual or auditory problems.

 

Patients who have developed symptoms of systemic problems need to report it to their orthopedic surgeon as soon as possible. Individuals who are to report their symptoms to their primary physician need to inform their doctors that they have an all-metal hip implant. It is needed for a prompt action of treatment. The worn out hip needs to be replaced because the problem might worsen. This was the reason why some patients have asked a Biomet lawyer to help them in filing a case.
