Defective metal on metal hip replacement

ALVAL from Metal on Metal Hip Replacements

What is ALVAL?

Metal-on-Metal (MoM) hip implants are known to rub off microscopic metal particles into patients’ bodies over time from friction. One of the health problems triggered by the elevated metal particles in the bloodstream is called ALVAL.

ALVAL is short for “Aseptic Lymphocyte-Dominant Vasculitis-Associated Lesions.”

Some MoM patients develop ALVAL because their metal implants trigger a reaction around the device. Essentially, the metal particles from the hip implant interact with the body’s immune cells, causing the body’s defense system to act like it’s being attacked. ALVAL can be very destructive and cause severe pain.

What are the Symptoms of ALVAL?

It is important to note that many patients with ALVAL experience absolutely no physical symptoms even though their bodies are undergoing a very damaging process. For this reason, the FDA recommends that all patients with metal hip implants get examined thoroughly by their doctors every 1 to 2 years. However, some of the most common symptoms associated with ALVAL are:

  • Moderate to severe pain in the hip or groin
  • Clicking, popping, or squeaking in the hip implant
  • Difficulty walking due to hip pain
  • Lumps or inflammation around the hip implant or groin
  • Restricted range of motion in the hip
  • Inability to bear weight on a leg

If you have experienced any of these symptoms in your hip, you should contact your doctor immediately.

How Common is ALVAL from Metal on Metal Hips

ALVAL is a well-documented and common health problem that results from metal hip implants; it can happen to patients with total hip replacements or hip resurfacings. One study of nearly 14,000 hips found that as many as 6.5% of hip replacements result in ALVAL or pseudotumors. Additionally, ALVAL is more common among females.

How is ALVAL from Metal on Metal Hip Implants Diagnosed?

Many patients only find out they have ALVAL after they’ve already gone through revision surgery because their doctors were able to directly inspect their hip joint. However, the process of diagnosing ALVAL before revision surgery can involve a number of steps, such as:

  • MRI scans
  • Ultrasounds
  • X-ray scans
  • Blood cobalt and chromium measurements
  • Harris Hip Score questionnaire
  • Testing a sample of fluid from the hip, white blood cell count, and tissue samples

My experience with mctlaw for my hip claim was remarkable, I found the communication to be outstanding. I also felt they did an excellent job setting expectations and then delivering on those stated expectations. From net amount, timing of the settlement, how much each related party would receive etc. they were outstanding. I would highly recommend them. They are very professional and set the bar in vaccine injury practice.


Five stars for mctlaw! Paralegal Leslie Williams did an outstanding job communicating with us and keeping us informed. Thanks for all the help.


I am excited to be receiving my final payment so I can put all this behind me. I am really grateful to everyone who played a part in getting me this well deserved settlement as my life has been negatively impacted over the years.


We cannot thank you enough for the services your firm has provided for Marie and I in our time of need. I could not have chosen a finer firm near or far to represent us.

My first response is “Wow!” It has only been 11 months since I first heard of “SIRVA” and an HHS program that awarded compensation to its victims and only 7 months since MC&T accepted my case. I feel that your efforts on my part made all the difference.
