DePuy Hip Implant Recall Frequently Asked Questions

October 27, 2010

As you may have read in our earlier reports, Johnson & Johnson subsidiary DePuy Orthopedics recently issued a major recall of two of its hip replacement systems.  Since that time, we have been inundated with questions from hip replacement patients who are concerned and confused about what to do when a device implanted in their body is "recalled" by the manufacturer. 

Due to the amount of confusion surrounding this issue, we've compiled a list of detailed answers for the most frequently asked questions.  We hope this helps provide guidance for anyone affected by this hip replacement recall.

Q1.  What types of hips are included in this hip implant recall?

A1. There are two types of hips that were recalled by DePuy:  The ASR XL Acetabular Hip System and the DePuy ASR Hip Resurfacing System.  Approximately 100,000 of these hips were distributed worldwide.

Q2. How do I know if I have and/or had a recalled hip?

A2. The first thing you should do is call the surgeon who performed your hip replacement surgery.  All surgeons who used the recalled hips were contacted by DePuy and advised of the recall.  Therefore, the surgeons should be aware of the recall and should be able to easily tell you whether or not you have a recalled hip.  If you are unable to get in touch with your surgeon or he is non-responsive, we suggest you request from the records department a copy of your "operative report" from the date of your surgery.  The operative report should identify the type of hip that was used in your surgery.

Q3. Why were these hip implants recalled?

A3. DePuy has indicated that it recalled the hips because it received data from Europe indicating that people who received its hips required revision surgeries at a rate that was more than five times what was expected. 

Q4. What are some of the symptoms someone with a recalled or problematic hip might feel?

A4. Common symptoms include:

  • Hip pain
  • Loosening of the hip joint
  • Swelling around the hip
  • Hip or leg numbness
  • Fracture of the implant
  • Tumors at the site of the implant
  • Flu-like symptoms
  • Chronic fatigue
  • Rashes and other skin conditions

Q5. Why does the "metal on metal" design of these implants cause problems?

A5. Although much is still unknown about why people have been experiencing problems, many experts suspect that it is due to excessive wearing of the implant and the subsequent release of metal debris into the joint.  The hip consists of a metal ball (that connects to the femur) and a metal cup (that is inserted into the hip socket).  In an attempt to increase the longevity of these hips and their range of motion, DePuy specifically designed the hips with a very shallow cup and large ball.  This design was substantially different than any other artificial hip that had been manufactured before.

However, it appears that DePuy's unique design for its artificial hip caused many unexpected problems.  Specifically, data suggest that many hips are experiencing excessive wear along the edge of the cup and that this is causing large amounts of metal debris to be released into the joint.  Although the released debris is very small, it can cause significant soft tissue injuries as the body reacts to the metal.  Specifically, the metal debris can kill nerves and muscles in the joint and cause other problems as the body's immune system tries to attack the foreign material.

There are additional concerns that the release of metal debris into the joint can cause problems throughout the body, known as metal toxicity.  Many reports have shown greatly increased cobalt levels (the primary metal that the hip is made of) in the blood of individuals who have received these hips.  Although there is no definitive scientific proof at this point, there are concerns that excessive cobalt in the blood system (cobalt toxicity) may cause heart problems, dementia, loss of hearing or eyesight, and cancer.  We are advised that because of this recall, several studies are currently underway to better understand the risks of excessive cobalt in the blood system.

Q6. If I'm not experiencing problems with my hip, do I still need a lawyer?

A6.  Yes.  The extent of the long term problems associated with these hips, including metal toxicity and cobalt toxicity, is currently unknown.  For example, it is presently unclear what types of long term disorders may be caused by excessive cobalt in the blood.  It is uncertain whether the cobalt levels in individuals with these hips will increase over time.  It is also unclear what the failure rate of these hips will be as time goes by.  Present studies are showing a revision rate of 13% at 5 years.  However, many experts expect that revision rate to greatly increase as the years go by.  If excessive cobalt in the blood is definitively linked to serious long term problems, doctors may eventually recommend that all of the hips be removed.

Unfortunately, if you wait until "something goes wrong" with your hip, you may be too late.  The law requires people to file a lawsuit within a certain period of time once they "suspect" there may be a problem with their hip.  In some states, this statute of limitations period can be as little as one year.  There is no doubt that DePuy will argue that anyone who has been made aware of the recall should "suspect" they have a claim, and thus the date of the recall notice would mark the beginning of any applicable statute of limitations.  Therefore, it is a very real possibility that if some catastrophic event occurs with your hip years down the road and you did not initiate a lawsuit within your state's statute of limitations, you will not be able to recover any damages for your injuries.  To protect yourself and your family, prompt action should be taken.

Q7.  Should I sign documents allowing my medical records to be released to DePuy?

A7.  No.  It is very important to understand that DePuy, as a company, is attempting to minimize its liability and will attempt to use information from your medical records to try and convince your doctor that any problems you've been experiencing with your hip are not its responsibility.  This could potentially affect the way your doctor views your condition and could impact your case down the road. 

Q8. What types of tests should my doctor be performing?

A8. Since we are not doctors, it is difficult to recommend the treatment patients should be receiving.  However, we can relay that most of the problems reported with these hips relate to soft tissue injuries; the destruction of muscle, nerves, etc, so X-Rays alone do not tell the whole story.  Many additional tests, such as MRI's and blood tests are necessary to determine the extent of the damage.

DePuy has put out a decision tree that it has asked surgeons to follow in treating patients with recalled hips.  Click here to see the tree.

To better understand if your doctor is "doing the right thing," we recommend that you bring the decision tree into your doctor and ask questions about each of the steps outlined in the tree.  Communication with your doctor is the most important thing you can do in dealing with the situation.

Q9. If my doctor wants to replace my hip, what should I do?

A9.  IT IS VERY IMPORTANT TO SPEAK WITH AN ATTORNEY IF YOUR DOCTOR WANTS TO REPLACE YOUR HIP.  One of the most important pieces of evidence in your case may be the artificial hip once it is removed from your body. 

There are many tests that can be performed on the removed hip to determine if there has been excessive wear as described above.  Therefore, steps must be taken to ensure that your surgeon maintains the removed hip and, most importantly, does not send it off to DePuy for analysis.  At Kershaw, Cutter & Ratinoff, we have developed a protocol to ensure that your surgeon does not discard your hip and that he maintains it in a way that will ensure its admissibility in a legal procedure.
