Hip Implant Failure
Hip implant failure is a known risk of receiving an artificial hip replacement. Hip implant failure generally occurs when the device or a component of the device fails to adhere properly to the hipbone. This is an extremely painful event that can lead to yet another hip replacement surgery. Though hip implant failure is a risk associated with hip replacement surgery, many individuals do not fully anticipate the ramifications that may occur if their device fails.
Symptoms of Hip Implant Failure
Symptoms of hip failure vary from patient to patient and can depend on the implant, but one symptom common among most hip replacement patients experience is extreme, often unexplainable pain in the hip. Other symptoms of hip failure include:
- Swelling in the lower back, hip, groin or leg
- Popping, clicking and squeaking from the hip joint
- Trace amounts of metal in the blood; disrupted blood flow through the bone
Treatment of hip implant failure
Unfortunately, hip implant failure treatment generally requires an additional surgery. Though hip replacement devices have improved in the last 20 years, thousands of people experience hip failure. When this occurs, a hip revision surgery may be required. Revision surgeries can be more complicated than the initial surgery because it forces surgeons to contend with scar tissue and bone corrosion that did not exist during the first surgery. However, this is often a patient’s only option.
Medical Device Complications
Zimmer hip implant failure has been studied and reported particularly with regard to the Zimmer Durom Cup. This hip replacement component was temporarily and voluntarily removed from the market by Zimmer, Inc. in 2008 after bowing to pressure from one of its leading consulting surgeons. The company re-released the hip device upon concluding that the device was sound.
Depuy hip implant failure has been widely associated with two of its popular models, the Pinnacle and ASR hip replacement devices. The latter was the subject of the DePuy hip recall issued in 2010 due a high incidence of hip implant failure resulting from DePuy ASR hip problems such as metallosis, implant dislocation and loosening of the implant. The Pinnacle, though never recalled, has nevertheless been the subject of widespread litigtion related to various forms of hip implant failure and other Pinnacle hip problems associated with device.
Stryker hip implant failure has been associated with two hip models, both of which have been connected with recalled component parts: the Trident, which reached the market in 2003, and the Rejuvenate, which was sold in the U.S. starting in 2008. After an FDA investigation into Stryker’s manufacturing plant in Ireland, and concerns about possible bacterial contamination of the implants, the Trident Hemispherical and Trident Acetabular PSL cups were recalled in January 2008. In July of 2012, the manufacturer also recalled the Rejuvenate Modular and ABG modular neck hip implants, citing reports of Stryker hip problems such as “excessive metal debris, excessive deterioration,” and the potential “need for revision surgery.”
