Metal-on-Metal Hip Implants Pose Danger To Recipients, Study Shows

Over the past few years, the orthopedic device production has been significantly critiqued by the medical experts and supervisory bodies, concerning the creation of hip implants where the effect brought is the rubbing of metal parts against each other.

The research into the implants identified that chromium and cobalt ions from this form of
man-made hip may penetrate its neighboring tissue to damage muscle and bone and circulate to the lymph nodes, spleen, liver and kidneys, probably causing injury.The research workers were also anxious the ions may affect one’s chromosomes, motivating genetic modifications.

Stryker Orthopaedics in their own free will, recalled two brands of its hip implant devices used in conjunction with unnatural hips in hip replacement surgeries, according to the website of the U.S. Food and Drug Administration.

There have been 45 cases of adverse reactions from patients, saying that it caused pain/or distension, and metal toxins.

The analysts say that creators of metal-on-metal hip implants distorted the design of the hips for more than 10 years now to heighten movement for the patient, though those alterations may be liable for the dispensation of toxins in the body.

Stryker’s head office is in Michigan, and runs its biotech division in Hopkinton, Mass., recalled Rejuvenate and ABG II modular-neck stems on July 2012 from the market, and finish global propagation.The company said the incidence of complications is extremely low, but people with these implants should make sure their primary care doctor knows they have one. 

“While modular-neck stems provide surgeons with an option to correct certain aspects of a patient’s anatomy and hip biomechanics, given the potential risks associated with fretting and corrosion at the modular neck junction, Stryker Orthopaedics decided to take this voluntary action,” Stryker Vice President and General Manager of Hip Reconstruction Stuart Simpson expressed in a statement.

Simpson voiced that the company would work with the medical community enhance knowledge about the complications with the devices as the company lingers to evaluate the adverse events.This contains at least 45 cases of damages, using the Rejuvenate modular-neck stem, at the start of 2012, FDA reports.

Recipients of metal-on-metal hip implants who are not suffering any of the side effects should still submit themselves to regular check-ups to their doctors.

For those that symptoms are aggravating three months or more after the metal-on-metal hip implant, they should seek instant help to their surgeon.
