Hundreds of injured patients are taking Stryker, a medical device manufacturer, to court, accusing the company of placing defective hip implants onto the open market.

In a growing litigation consolidated in Massachusetts federal court, patients and their families say Stryker concealed the risks of a now-recalled hip replacement component, the LFIT V40 Femoral Head, leaving them to suffer severe complications. All too often, the consequences have been disastrous: every plaintiff claims to have undergone at least one invasive and costly hip revision procedure.

Implant Failures Lead To Hip Revision Procedures

Stryker’s LFIT V40 Femoral Head has been associated with an increased risk of premature device failure. The vast majority of hip replacement systems are designed to last for years. As the University of Maryland Medical Center reports, around 80% of hip implants last for at least 20 years after implantation.

Stryker’s hip component, however, appears to fail far quicker than that. In their lawsuits, plaintiffs report device failures within 7, 6 and even 1 year following implantation.

How Revision Surgeries Work The Second Time Around

When a hip implant fails, either by breaking apart, loosening from its site of implantation or causing internal tissue damage, the only viable solution is to remove the offending device and replace it.

Hip revision procedures can often be similar to initial implantation surgeries, but tend to take longer and pose a higher risk for certain serious complications.

Bone Loss & Additional Procedures

In patients who have already lost a significant amount of bone mass, the revision process may require surgeons to perform additional procedures, including bone grafts, to prepare the site for further operation.

At the same time, keep in mind that hip revision surgeries, as with primary hip replacement operations, tend to occur in older patients who have developed some level of arthritis in the hip and may also be dealing with weakened bones.

Risks & Complications

Due to these factors, Cedars Sinai reports, “the success rate for revision surgery is usually lower than that for the original surgery.” As particular risks, the California hospital notes:

  • Infection
  • Device loosening
  • Bone fractures
  • Device dislocation (nearly twice as likely after revision procedures than original hip replacement)
  • Leg length discrepancies
  • Bone loss

Needless to say, any one of these complications could increase the likelihood of yet another revision procedure in the future. Some patients have become locked into a cycle of operation and re-operation, as each of their implants fails due to complications caused by the preceding re-operation.

Hip implant failures are generally more common in patients who engage in strenuous exercise, as well as those who have pre-existing bone disorders, like osteoporosis, or are overweight or obese.

Infected Implants Require More Surgery

That changes, however, when the old hip implant is infected, a common complaint cited in many Stryker LFIT V40 lawsuits. To replace a hip that has become infected, surgeons usually need to perform two separate surgeries.

In the first procedure, the infected device is removed, along with any surrounding tissue damage, and antibiotics are administered to control the infection. After the disease has subsided, surgeons re-open the patient’s hip to implant a new prosthesis.

In the rare cases when a hip infection is identified quickly, surgeons may be able to “clean” the implant site without removing the replacement device altogether, but the cleaning process still requires at least one invasive procedure.

Why Did My Hip Replacement System Fail?

Hip implants aren’t permanent devices. Over time, hip replacement devices wear down, as their components slide together during normal use. Some implants, though, are prone to degradation of a different sort.

Metal Deterioration

Metal-on-metal hip implants frequently release minute particles of metal into the soft tissues surrounding the device’s site of implantation. This can lead to devastating complications, along with undesirable physical symptoms that make it harder to live, but it also has a major impact on your hip implant.

Symptoms Of Device Failure

The metal particles eventually weaken bones, muscles and soft tissues that are required to hold the implant in place. As the deterioration progresses, the implant can come loose, or break entirely, leading to failure. Identifying a failed implant requires medical diagnosis, but most patients who will eventually require a revision procedure become aware of the problem through the sudden onset of symptoms:

  • thigh, knee or groin pain (especially during movement)
  • swelling around implantation site
  • loss of mobility

Metal implant deterioration is likely the leading cause of device failure, when the failure can be attributed to mechanical causes.
