Metal-on-Metal Implant Risks
The most common problems that are associated with the ever popular hip transplant procedure occur when the friction of metal on metal reaction takes place at the point where the artificial metal ball and metal cup that have been installed to replace the original hip components begin to break down, sometime after they have been installed. It is often described much like the metal on metal sensation auto owners experience when their brakes begin to fail.
That constant grinding action causes minute particles of the metal surfaces used in the construction of the hip components (usually chromium and cobalt), to break off into microscopic ions that release a form of metal poisoning into the bloodstream and lymph nodes. Every person is able to absorb and store a certain amount of these components. But, when the liver can no longer hold any additional toxic fluids, the excess must then be transferred to the nodes and kidneys where it is stored until such time when it released in the urine flow.
When the level of that dangerous toxic metal discharge becomes excessive – and the kidneys become overburdened with that toxic material, they are not able to reduce the toxicity levels sufficiently.
The breakdown in the metals used to manufacture artificial hips has been the cause of various recalls and lawsuits. Hip Manufacturing companies such as Depuy and Stryker have been involved in huge defective hip claim cases approaching a billion dollars.
Hip transplant complications
- The loosening of the joint in the vicinity of the prosthesis and thigh bone.
- Hip dislocation in the first months after surgery
- Wear and tear after several years
- Blood clots near the tissue
The successes seem to have vastly overcome the dangers, as millions of successful hip transplants have occurred over the past decade alone. The benefits far outstrip the dangers.
Other Metal Hip Complications Include
- Visual impairment
- Cognitive impairment
- Nerve problems
- Thyroid problems
- Skin Rashes
- Implant loosening
