Biological hip joint replacement may be better option for younger patients than traditional hip replacement

Researchers at the University of Missouri School of Medicine have been busy testing a new technique for biological hip joint replacement surgery. This technique is designed to give younger, more active patients better and longer-lasting joint function, and is intended to reduce the pain caused by traditional total hip replacements. Total hip replacements involve using an artificial hip with plastic or metal components that begin to wear right away. These traditional repairs have a limited life expectancy and usually require restricted activity. In the past 20 years, manufacturers such as Johnson & Johnson and DePuy Orthopedics, among others, have designed some ... Read More

Woman’s pain, itching, migraines traced to defective metal hip implant

For two years, Paula Spurlock suffered from unexplained pain, itching and migraines and no doctor could seem to find the source. It wasn’t until she underwent a PET scan that it was discovered that the all-metal hip replacement system she received in 2008 was corroding inside her body. Further studies showed that the metal-on-metal device was leeching metal ions into her bloodstream, causing a type of blood poisoning known as metallosis and triggering her unpleasant symptoms. Traditional artificial hips are made with ceramic or plastic parts. The newer, all-metal hip implants were designed so that they could last longer and ... Read More

Organic joint could one day replace artificial hips and knees

Researchers at the University Health Network in Toronto are working to find a biological cure for joints that become damaged by osteo-arthritis that may someday replace invasive knee and hip replacement surgeries. Dr. Nizar Mahomed and colleagues are conducting a series of experiments, one of which uses stem cells to create bone and cartilage, which they hope can be turned into a sort of organic joint implant that would fuse with existing tissue and regenerate diseased knees and hips. The prospect is intriguing, especially since thousands of people with arthritis seek relief from chronic pain with knee and hip replacement ... Read More

DePuy artificial hip patients may be victim of faulty design

Stephen Ellis, 57, of the United Kingdom, was furious when he learned that black liquid drained from his right hip joint during revision surgery to replace his two-year-old metal hip implant which had started poisoning his blood. Ellis suffers from rheumatoid arthritis, and is among thousands of Liverpudlians who have had to undergo revision surgery to replace their faulty hip implant. All told, about 93,000 people worldwide, including in the United States, are affected by a recall of one brand of metal-on-metal hip implant, the ASR made by DePuy Orthopaedics, a subsidiary of Johnson & Johnson. While the medical device ... Read More

House Democrats push for closer review of metal-on-metal hip implants

House Republicans are being urged by Democrats to investigate the safety of metal-on-metal artificial hips, such as the recalled DePuy Orthopaedics ASR XL systems, and the process by which those devices are approved. The request was made by Energy and Commerce Committee chairman Rep. Henry Waxman of California. Hip implants are typically made from ceramic or plastic parts. But some newer varieties are constructed with metal-on-metal parts. This design is intended to be more durable and last longer than traditional implants. Instead, they have been found to fail at a higher than expected rate. Metal-on-metal hip implants involve a metal ball ... Read More

House Dems request hearing on metal-on-metal artificial hips

House Democrats are urging Republicans to investigate the safety of so-called metal-on-metal artificial hips and the process by which those devices are approved. The request was made by Energy and Commerce Committee Chairman Rep. Henry Waxman of California. Hip implants are typically made from ceramic or plastic parts. Many newer implants are made with all metal parts. This construction is designed to be more durable and last longer than traditional implants. However, the material used to make the devices stronger has been found to cause the devices to fail at a higher than expected rate. Metal-on-metal hip implants involve a ... Read More

Metal-on-metal implants linked to pseudotumors

Metal-on-metal hip implants have flooded the artificial hip market in the past five years with claims of being more durable than traditional ceramic implants. But the devices have created a new post-surgical complication – a pseudotumor, a tumor-like mass resulting from an inflammatory reaction, according to an article published in OrthoSuperSite. Problems with metal-on-metal artificial hips aren’t new. In fact, the Food and Drug Administration (FDA) ordered a review of all metal-on-metal implants due to mounting complaints. Metal-on-metal hip implants are made by 21 different manufacturers.. Problems with the metal-on-metal devices include loosening, fracturing and dislocating of the device caused ... Read More

DePuy refuses to compensate faulty hip implant victims for pain, suffering

About 500 lawsuits have been filed against DePuy Orthopaedics, the makers of the ASR metal-on-metal hip replacement system. Plaintiffs claim the Johnson & Johnson subsidiary knew its artificial hip was defective and was failing at a higher than expected rate just months or a few years after surgery, yet DePuy continued to market it to physicians. In response to a federal lawsuit filed in January in the Northern District of Ohio, DePuy denied its devices were defective or dangerous and denied making any false representations. They also said patients who had had to undergo revision surgery to have their implants ... Read More

Months after worldwide recall, FDA approves another DePuy artificial hip

A ceramic artificial hip system made by DePuy Orthopaedics has been approved for marketing by the Food and Drug Administration (FDA). DePuy’s new Ceramax Ceramic Total Hip System is a ceramic-on-ceramic artificial hip replacement system that is surgically implanted to completely replace a hip joint that is painful or cannot function because of arthritis, injury or dislocation. The system could replace another type of artificial hip implant made by DePuy, which was recalled last August after reports that the devices were failing at a higher than expected rate. DePuy’s new device consists of a metal hip stem that a doctor ... Read More

Hip replacement surgery complications

Hip replacement surgeries are required once medical treatment has been deemed ineffective or a disease has progressed to severity. The indications for surgery include severe pain, loss of movements, and the inability to perform activities of daily life. While the surgery can help reduce pain and restore mobility, hip replacement surgery is a major, invasive process and complications may occur. During surgery, nerves in the vicinity of the total joint replacement may be damaged. While this is a rare complication, it is more likely to occur when the surgery involves correction of major joint deformity or lengthening of a shortened ... Read More
