Hip implants can help those suffering from arthritis and other degenerative hip conditions by alleviating pain and improving mobility. DePuy is one of the most popular hip implant manufacturers in the world. Their Pinnacle Hip Replacement System, ASR Hip Resurfacing System, and ASR XL Acetabular System are intended primarily for younger patients, as they allow for greater range of motion and increased flexibility. However, the devices’ durable metal-on-metal design has led to a variety of medical complications and adverse reactions.
How DePuy Hip Implants Work
DePuy hip implants are constructed of a range of materials, including titanium and cobalt chrome. The system itself typically features four key components: a stem, shell, head, and liner. The artificial shell takes the place of the faulty acetabulum, which is the rounded socket found within the pelvic bone. The artificial stem is then placed into the femur, and the artificial head fits into the acetabulum. After a recovery period following the hip implant surgery, the patient should be able to move more freely, due to the fact that the deteriorating hip joint has now been replaced by a metal prosthetic.
DePuy Hip Implant Recall
DePuy, which is a business unit of Johnson & Johnson, voluntarily recalled their ASR hip implant in August of 2010. This includes the ASR XL Acetabular hip replacement and the ASR Hip Resurfacing System. Before the recall took place, a number of studies found that the device was linked to serious side effects, such as:
Allergic reaction to the metal debris created by the device
Soft tissue masses that form as a result of metallic allergic reactions (pseudotumors)
Metal poisoning (cobalt or chromium)
Groin, hip, or leg pain
Hip joint swelling
Diminished mobility (limping or decline in the ability to walk)
Some of the adverse reactions patients experienced were tied to a loose ASR hip cup component within the device.
Patients who received a DePuy ASR hip implant may be eligible for compensation or benefits as a result of their injuries. Speaking with a qualified legal professional can help patients and their loved ones determine if they may be entitled to medical bill repayments, lost wages, and other reimbursements that were caused by DePuy hip replacement systems.
