Another Lawsuit Lodged Against Stryker in Kentucky Court

A new lawsuit against Stryker has been filed in a Kentucky court by plaintiff John T. Roberts who was implanted with Stryker Trident acetabular shells and Accolade hip stems in both hips back in 2006. These two devices were recalled in 2008 and 2009, respectively.

In March 2011, Roberts was compelled to undergo revision surgery on both hips to change the Trident acetabular cups. In 2013, he had to undergo another surgery to get rid of and replace the Acolade hip stem in his left leg after it ruptured.

According to the lawsuit he filed, “the defective nature of the Stryker hip components have caused him serious physical injuries, resulting in past and ongoing medical expenses, lost wages, and a diminished earning capacity.”

FDA Releases Latest Metal-on-Metal Hip Implant Safety Communication

Inside scoop on hip implants by Stryker

The latest safety protocol for metal-on-metal hip implants was announced by the US Food and Drug Administration (FDA), proposing recommendation for physicians, healthcare providers, prior recipients, and product manufacturers, such as Stryker, over compliance issues, says an international wire service agency. The proposal stated the need of the medical product manufacturers to undergo rigid testing to ensure the safety and quality of their product and to prevent future problems, before they are approved to use.

Stryker and other hip replacement implants manufacturers are continue to face a number of lawsuits due to their defective products, which resulted to harm its users.

US Senator Wants Medical Device Tax Cancelled

About 1,170 workers worldwide from Stryker Corp, maker of Rejuvenate and ABG II hip replacement devices, may lost their jobs due to the anticipation of the 2.3 percent medical device tax for Obamacare. However, US Senator Kay Ruthven Hagan is contriving to cancel the tax to avoid lay-offs in the medical industries, says a medical device industry news website. She is worried that many medical industry workers in her home state (North Carolina) may potentially lose their jobs, that is why she is trying to brainstorm ideas with business leaders in her state. She is in favor of funding Obamacare, but does not want the revenue created at the expense of her state’s economic health.

Graphite Lubricant in Metal Hip Implants Paves Way for Better Hip Implant Design, Study Shows

Stryker hip replacements cause grief to hip injury victimsA lubricating layer made of graphitic carbon consequently forms in the joints of metal-on-metal hip implants, according to a study. This dense layer works more like an industrial lubricant than joint fluid. This discovery may aid researchers design longer-lasting metal-on-metal hips for osteoarthritis and other joint disorder therapy. Undertaking a hip replacement surgery is very risky. In fact, more and more patients have been distressed and endangered, leading to the filing of lawsuits. Although, the complainants worry that the court will dismiss their lawsuits.

Osteoarthritis is a painful condition frequently characterized by inflammation of the joints. It is usually the cause of disability in people as they grow older. The swelling of the joint may damage tissue and bone, in the end making the joint really painful. To pacify the condition, orthopedists resurface or change the joint with an implant.

Normally used hip implants are made of metal and polyethylene, a type of plastic. In the long run, metal and plastic joints wear down, and metal fragments may damage the remaining bone and tissue of the hip. In the last 10 years, all-metal joints have become progressively widespread, as they are mostly more firm and long-lasting. In some instances, though, metal-on-metal hip implants can still shed harmful metal debris over fretting and corrosion.

Metal-on-metal joints are not made with lubrication, but when used, a thin layer emerges in the joint between the ball and socket. This layer, which forms between the two rubbing metal faces, is called a tribological layer. Researchers originally thought that it was made of proteins and other biological material, similar to the lubrication in a normal joint.

The researchers studied the tribological layer on seven all-metal joints that had been detached from patients. They scraped off a bit of the layer and evaluated it by electron energy loss spectroscopy, a technique that exposes the type of atoms present in a material. The researchers did not see this coming. They learned that the layer was made up in large part of graphitic carbon, with slight or no traces of protein at all.

“Knowing that the structure is graphitic carbon really opens up the possibility that we may be able to manipulate the system,” states coauthor Dr. Alfons Fisher of the University of Duisburg-Essen, Germany. “We now have a target for how we can improve the performance of these devices.”

With this information, researchers will be able to produce safer, durable hip implants by making graphitic carbon to stick to the metal of the implant. This will lessen the cases associated with the recalled Stryker ABG II.

Voluntary Recall Does Not Solve All of Stryker’s Problems

It was just a few months ago in July 2012 when Stryker Orthopedics did a voluntary recall for two of their hip replacement devices, the Rejuvenate Modular and ABGI II modular neck stems.  According to Stryker, this is due to the risk of fretting (wear-and-tear) and corrosion at or about the modular-neck junction.

But the story does not end there, there is another hip replacement system that has been causing problems for Stryker. The Stryker Trident hip replacement parts are relatively new, featuring ceramic-on-ceramic parts.  Stryker promoted the Trident as to be more durable and supposedly longer lasting than the conventional metal-on-plastic or metal-on-metal hip replacements.  Soon after receiving a Trident implant many patients began to feel severe pain, loud squeaking in the hip joint, loosening of components and premature wearing.

A recent issue of the Journal of Arthroplasty, a study indicated that roughly seven percent of the patients who received a ceramic-on-ceramic hip replacement showed the squeaky hip side effects.While some medical experts believe that this squeaky hip side effects is not harmful to patients, other fear that it is a precursor to other side effects which an require a second surgery or removal of the implant.

As more and more patients are learning of the recent recall done by Stryker more and more lawsuits have begun to get filed against the orthopedic company.  The majority of these lawsuits carry the main complaint as that the patient requires surgery to remove or to fix the replacement and Stryker may not pay for the surgery nor the update of hip replacement.  The patients who filed a case most recently advised that they were implanted with their devices between June 2009 and September 2011 and underwent corrective revision surgery in as little as eight months.  It was shown that in that all cases, during revision surgery it was shown that there was a the presence of milky, turbid fluid; large pseudo-tumor formation; soft tissue necrosis; muscle loss and/or bony necrosis at the proximal femur.

If you are still having problems with your hip problems and of you’re having a hard time keeping up with them, then it is advised that you visit your physician as soon as possible.
