Patients with Metal-on-Metal Hip Implants Much More Likely to Need Revision Surgery

Patients that have received metal-on-metal hip implant devices are far more likely to need revision surgery, an article by verywell.com states. Jonathan Cluett, MD, contributed his expertise in an article published by the website providing information to patients that have received metal-on-metal hip implants, and what they should do if they are experiencing problems. Metal-on-Metal hip implant designs were recommended for patients with a more active lifestyle, based on claims the all-metal system was a better fit for their needs. But many of the implants were failing at an alarmingly high rate, whereas traditional models made of ceramics and polyethylene can last as long ... Read More

FDA Cleared Metal-on-Metal Hip Implants without Clinical Testing

When Consumer Reports did an investigation regarding the FDA and approved medical devices designed to be implanted into the body, what they found was disturbing to say the least. “Medical devices often aren’t tested before they come on the market,” Consumer Reports says. That was the case for the DePuy ASR XL metal-on-metal hip that has allegedly injured thousands of patients, including Stephen Tower, M.D., a 55-year-old orthopedic surgeon. About a year after receiving his hip implant, Tower could tell that something was wrong. He experienced pain from his hip “pretty much constantly”, his chromium and cobalt blood levels were through the roof, ... Read More

ASR Metal Hip Implant Has Failure Rate of Up to 50 percent Within Six Years

According to an article published by BMJ, ASR metal-on-metal hip implants such as the designs made by DePuy Orthopaedics, a subsidiary of Johnson & Johnson, are shown to have a failure rate of up to 50 percent within six years. “Metal on metal joints are designed to harness naturally occurring lubricating fluids from the native hip,” the article reads. “As wear debris is generated, hip joints become filled with high concentrations of chromium and cobalt. This leads to a chain of events culminating in extensive soft tissue necrosis and disruption of bone. The metallic ions then diffuse into the blood stream.” But the ... Read More

Doctor Warns Against Using Medical Device He Invented

Dr. Scott Augustine, an anesthesiologist in Minnesota, decided to explore ideas on how to keep a patient warm during surgery. The Bair Hugger forced-air warming  blanket system was developed in 1987 and is now used in 4 out of 5 hospitals across the U.S. The medical device was intended to keep the patient warm during and after surgery, reduce the risk of unintentional hypothermia, reduce bleeding, and promote a faster recovery. But when patients started coming forward with claims that the Bair Hugger caused deep-joint infections, Dr. Augustine agreed with them. The device works like a forced-air heater by pushing warmed ...

Dying Patient Fights to Have Hip Implant Suit Processed in State Court

Deborah Aldrich, a victim of stage 4 pancreatic cancer, has asked to remand her lawsuit against Wright Medical Technolgy Inc. to state court instead of federal court, so that the suit could proceed at a faster pace. Aldrich has been given a mere six months to live, and has argued that her cancer could end her life before she has the opportunity to testify in her own case. Aldrich is only one of more than 1,000 lawsuits claiming Wright Medical Technology’s hip implants are causing injuries because of their faulty metal-on-metal design. When the metal parts of the device rub together, flakes of metal can chip ... Read More

Joint-Surgery Patients may Risk Infection with Bair Hugger Warming Blanket

The Bair Hugger is a single-use FAW (forced-air warming) device that is placed over the patient during or post-surgery to help maintain body temperature, reduce the risk of infection, increase comfort and reduce risk of unintentional hypothermia. But 3M, the maker of Bair Hugger, is finding itself battling claim after claim by surgery patients that the FAW blanket caused infection, more than 50 of which are orthopedic surgery patients that suffered deep-joint infection. The Bair Hugger blanket is used in 4 out of 5 hospitals across the U.S. and has been a popular method of body temperature maintenance since 1987. However, Dr. ... Read More

New 3D-printed Titanium Hip Implant Unveiled

Smith & Nephew, a global medical technology business, has creatively designed a titanium hip implant using 3-D technology. The new REDAPT™ Revision Acetabular Fully Porous Cup with CONCELOC™ Technology is designed to be used in revision cases where implant fixation and stability is made more difficult by compromised bone. A 3-D process produces an entirely porous implant that allows ingrowth and mimics the structure of cancellous bone. The stability of the implant can be strengthened using new variable-angle locking screws, and minimizes micromotion following surgery. The FDA has cleared the use of REDAPT Cup in November 2015, but was just officially ... Read More

Texas Woman Claims 3M Bair Hugger Device Caused Infection Leading to Amputation

Texas state court has recently dealt with a lawsuit from a woman claiming 3M’s Bair Hugger device is responsible for exposing her to a drug-resistant infection that ultimately resulted in leg amputation. Ruth Childers of Texas is seeking $1 million from 3M and three other defendants for selling and using Bair Hugger on her while undergoing knee replacement surgery in December 2013. The device is a disposable blanket with warm air circulating through it, intended to keep the patient warm and comfortable while reducing bleeding, risk of infection and post-operative heart attacks. However, lawsuits including Ms. Childers’ allege the device has potential ... Read More

Newer hip implants may not be better than older models

When Dr. Art Sedrakyan and fellow researchers published the first paper on premature failures of metal-on-metal hip replacement systems in 2011, several medical device manufacturers responded by withdrawing their all-metal hip implants. It turned out the failures were caused when the metal parts rubbed against each other, causing metal bits to inflame neighboring tissue and leech into the bloodstream poisoning the blood. “Back in 2011 when we published the first paper on metal-on-metal hips, hundreds of people contacted me and asked if they should be worried about hip replacement in general,” says Sedrakyan, of the Patient Centered Comparative Effectiveness Program ...

Readers warn people with metal hip implants to have their blood checked for metal ions

“If you have a metal-on-metal (hip) replacement, it is imperative to have the metal ion test as soon as possible,” warned BJackson, in a comment on Missoulian’s Letters to the Editor. “My neighbor’s wife passed away a little over a year ago because of cobalt and chromium poisoning. .. she had the offending metal-on-metal (hip implant) removed and a new hip put in, (but) it was too late for her. They had spent three years telling her that she had ALS, but they were incorrect, and it was the metal-on-metal (hip implant) that killed her.” The comment was posted in ... Read More
