Hip replacement operation has been changing lives for 50 years now.It was Sir John Charnley of England who was responsible for the first hip replacement surgery to happen. Since then it has been helping thousands of people with bone diseases and is considered as one of the most successful operations in all of medicine. The Agency for Healthcare Research and Quality reported that about 285,000 cases of total hip replacements are done annually in the United States. Stryker hip replacement implant is a recognized orthopedic brand by doctors used in a hip replacement operation.
Nothing like a typical hip implant device, Stryker Rejuvenate and ABG II hip prostheses offer much flexibility.They are comprised of metallic necks and stems.With this, it will be easier for surgeons to prepare anatomically correct implant components.
But in spite of the advantages, fretting and corrosion may be prompted still.Fretting because of too much movement of the different parts, and corrosion as it is made out of metals and it will most likely to shed some metal parts that may cause inflammation, pain, and metallosis.
Metallosis or metal poisoning is a dangerous medical condition in which there is build-up of metal debris around the soft tissues of the body near the implanted hip device. Eventually, this may seep into one’s bloodstream resulting to injury to some body organs.
If you are overweight, female, or with small body frame there is a big possibility that you will suffer from metallosis due to your body type as it will add strain to your implant and increases the amount of metal ions in the bloodstream.
This pressed Stryker Corporation to withdraw their products, Stryker Rejuvenate Modular and ABG II modular-neck hip stems on July 2012.As a result, recipients of these hip implant devices filed complaints as they experienced the unwanted effects of it.
Dr. Robert Zann, an orthopedic surgeon in Boynton Beach, Florida said, “The numbers of Stryker hip implant recall patients needing revision surgery has exhausted some doctors. For patients, the situation is even worse, as tissue and bone damage often leaves revision patients in worse shape than before.”
Furthermore, almost 20,000 Stryker Rejuvenate and ABG II hip prostheses were put on the market before news of it being withdrawn spread.
