Soft Tissue Imaging & Metal Ion Testing
Fort Lauderdale Hip Implant Lawyer
Numerous all-metal hip implants and hip implants with metal components
have been recalled, and thousands of lawsuits have been filed against
hip implant manufacturers. Claims of implant failure, metallosis, tissue
damage, and infection have made metal hip implants
one of the costliest implant recalls in U.S. history.
The FDA recommends that patients who are experiencing symptoms of hip implant
failure or metallosis receive additional testing to monitor and assess
their hip implants. In particular, two tests are recommended: soft tissue
imaging and metal ion testing. If you received a metal-on-metal hip implant,
it is important to contact your doctor soon.
Soft Tissue Imaging Methods
For some patients, cross-sectional imaging may be needed to assess the
soft tissue near the implant.
Metal-on-metal hip implants can cause shards of metal and metal ions to become embedded in surrounding
hip and joint tissue. This can cause necrosis of the tissue and pain.
Assessing the tissue in the joint can be done in three ways:
Magnetic Resonance Imaging (MRI)
MRI often offers the best visualization of soft tissue; however it is
not recommended for some patients. Heating of the tissue near the implant
could occur in some implants, making it less reliable.
Computed Tomography Scans (CT Scan)
CT scans usually offer the best visualization of bony tissue and implant
positioning, but ionizing radiation during the test provides lower soft
This method offers good soft tissue visualization, but image quality is
often poor and provides lower resolution than MRI.
Your physician can determine the best image test to undergo; however, the
Orthopaedic and Rehabilitation Devices Advisory Panel recommends MRI imaging
with metal artifact reduction as the best way to view soft tissue surrounding
the hip implant.
Metal Ion Testing
The FDA is concerned about higher metal ion levels in the blood in patients
with metal hip implants. Patients with metal hip implants may have higher
than normal levels of cobalt and chromium and should be evaluated. Obtaining
accurate metal ion testing is difficult, however, and not all labs can
accurately and precisely measure trace elements. If your physician recommends
metal ion testing, you should have your blood or joint fluid tested at
a lab that is CLIA-certified. The FDA recommends testing cobalt and chromium
in EDTA anti-coagulated whole blood.
Who Should Be Tested?
At the moment, the FDA does not recommend that patients without symptoms
undergo routine testing. Patients who are experiencing symptoms of hip
implant failure should be evaluated and assessed for soft tissue damage
and metal ion toxicity.
Patients with the following symptoms should immediately contact their doctors:
- Pain in hip joint
- Swelling in hip
- Change in walking ability more than three months after implant surgery
- Joint infection
- Implant loosening
- Palpable hip mass
- Popping or clicking sounds when walking
- Peri-prosthetic fractures
- Dislocation of the hip
- Local nerve damage
