Over time, pelvic joints wear down due to age or injury, and a joint replacement using Depuy and Stryker hip implants have been a popular choice among patients and surgeons. More than 500,000 procedures are performed every year, and musculoskeletal issues are the number one reason for chronic pain and physical impairment. However, these implants have recalls that have been linked to several severe complications that can further impact the quality of one’s life.
This sector of the medical industry racks up more than $250 billion in expenditures every year, and as society in the U.S. continues to get older and older, pelvic replacement will become more important. Depuy and Stryker hip devices are known as total joint replacement, or TJR, implants. They are meant to function like actual joints, and are usually made from a combination of metals, ceramics and polyethylene. There are three main segments to the device – the acetabular cup, the femoral component and the articular interface. The acetabular cup is the part of the implant that goes into the socket. The femoral component attaches to the thigh bone, and the articular interface is the area where these two parts connect.
All joint replacements come with some measure of risk, but Depuy and Stryker hip devices are being recalled for an unusually high number of incidents. Many of these extra complications have forced patients to seek out a second surgery to fix up the issues caused with metal on metal devices. These problems may include vein thrombosis, dislocation (which is the most common complication following replacement), osteoysis, metal sensitivity or toxicity, leg length inequality, nerve palsy or chronic pain. Osteoysis is bone loss caused by polyethylene micro shards shaving off of the implant. These shavings inflame the area and prevent bone resorption, which is a process the body uses to break down and build the bone back up.
Metal on metal devices can, over time, wear down very slightly, depositing metal particles in the area. A patient with sensitivity to these may experience an allergic-like immune reaction. This may result in organic masses accumulating in the area that are laced with necrotic tissue. These concerns may require a second surgery to mitigate, and Depuy and Stryker hip implants have required a high number of revision surgeries. Specifically, one in eight people who received the device required a revision surgery to correct problems associated with the replacement.
The ASR Hip Resurfacing System has been recalled by the company along with the ASR XL Acetabular System, covering around 93,000 units and 29 different models. The remaining products from this manufacturer have been removed from the market and are no longer available for patients.
Anyone that has received a Depuy and Stryker hip replacement and experienced any of the aforementioned complications should contact a personal injury attorney to learn about their options concerning restitution. Because mass tort is involved (mass tort is a mistake or wrongdoing committed by a party that affects many people), scores of people have already filed cases against the company. An experienced legal advisor can guide their client through the entire process and help them receive the maximum restitution for their pain and suffering.
