There are three types of hip implants: ceramic on ceramic, metal on metal and metal on plastic. Each of these hip implants has its advantages and disadvantages. Medical professionals look at all factors when deciding which type of hip implant should be installed into a patient. The condition of the original joint, the age of the patient and past medical history are important factors the doctor must evaluate before prescribing hip replacement.
Various recent studies have shown that the metal on metal implants have developed failures in proportions much higher than other hips replacements. The main reasons of the failure in metal on metal implants are metal particles or ions, which are produced as a result of regular wear and tear. These metals are absorbed into the bloodstream and damage the surrounding tissues. This normally causes pain and disability that may require revision surgery.
Rejuvenate and ABG II Hip Systems
The Stryker Corporation is one of the main companies, which provides hip replacements to thousands of patients. It is one of the Fortune 500 companies and has been, until recently, known to provide safe and high quality products. Two of the hip implant models manufactured by this company are the Rejuvenate and ABG II hip systems. These implants were composed of multi-components, which would help the patient have a greater range of motion, more stability and less bone stress.
Both of the systems were metal on metal hip replacements. After various complaints by patients using these models, it was found that both Stryker models failed to adhere to the claimed safety measures. In 2012, both products were recalled and production was halted. The company urged all patients who had the implants installed to seek medical attention immediately to locate any possible reactions or blood poisoning.
Provided the Public with Unsafe Products
The company was aware of its inability to conduct sufficient safety tests. The FDA has a clause, which allows new products that are similar to other products already approved, to be sold in the market with less confirmatory tests than required by other products. This is the loophole that Stryker used to sell its products. The Stryker Company had an ethical responsibility to only make those products available the public, which had been tested and were deemed safe.
It was also the company’s responsibility to make users aware of possible side effects. Stryker failed to warn their patients about the side effects or drawbacks that their products may create. In this particular case, Stryker did not inform users that there was a possibility of metal poisoning or erosion of tissues.
Lawsuits Cause Company to Set Aside More Funds
Various lawsuits have been filed against the Stryker Company on these exact grounds. Failure of notifying a user of the possible adverse effects is enough for a lawsuit. As more and more patients are becoming aware of the issues with both models, the number of lawsuits has been increasing. Stryker has been allocating funds to resolve the many lawsuits surrounding the Rejuvenate and ABG II Hip implant products.
