Miss the Filing Deadline for Your DePuy ASR Hip Case? There May Still Be Hope

Despite the fact that the August, 2010 recall of the DePuy ASR metal-on-metal hip implant caused a significant stir among the medical community, thousands of recipients of the metal implant remained unaware of recall and subsequent warnings. Due to the initial FDA notice which was issued July 17, 2010 and the recall of the implant on August 24, 2010, all those who live in a state which operates under a two-year statute of limitations may have already lost their right to file suit against DePuy and Johnson and Johnson. Over half of the states do operate under that two year SOL, while others extend that time limit to three, four, six or even ten years. A handful of states have a one-year statute of limitations.  If you are the recipient of a DePuy metal hip implant it’s important that you determine your state’s statute of limitations for defective medical products even if you are currently having no problems with your implant.

Although DePuy originally set their metal implant’s failure rate at approximately 5%, they increased that number to 12% at the time of the 2010 recall. Independent studies place the likelihood of a DePuy ASR implant failure much higher—50% at five years following implant surgery and 80% at eight years following implant surgery. Statistically speaking, even those patients who have not yet experienced failure of their hip implant or adverse health effects from metal toxicity will do so in the very near future. It is extremely important that all DePuy ASR implant recipients at least be aware of their options prior to the date the statute of limitations will run.

“ASR” type Chromium and Cobalt Poisoning also being seen in Pinnacle Hip Implant Recipients

The DePuy ASRmetal-on-metal hip implant has repeatedly made the news following a voluntary recall on August 26, 2010. While DePuy’s Pinnacle metal hip implant has not suffered under the recall stigma, many feel that it offers the same risks to implant recipients as the ASR. And, in fact, many attorneys are constantly asked by their clients about the differences between the ASR and the Pinnacle. The primary distinction between the two metal hip devices lies in the fact that the Pinnacle uses an insert liner between the acetabular cup and the femoral head while the ASR does not. It has been theorized that the ASR cup was too shallow for the head, leading to the ball hitting the edge of the cup and metal shavings to shear off into the body, also know as edge-loading.

While the Pinnacle’s cup was designed to give greater depth and allow the femoral head to move more freely within the socket, in some cases it still has been know to cause metallosis in implant recipients when the cobalt and chromium ions migrate around the body. Metal poisoning can cause a wide variety of adverse medical events. Many ASR recipients have had cardiovascular, renal, neurological and thyroid issues although studies done in the 70’s do not definitively tie these metals to cancer. Unfortunately, due to the lack of comprehensive studies on safe levels of cobalt and chromium in the body and the effects of toxic levels, nobody really knows just how dangerous these metals can be should they migrate to the bloodstream. The metal shards can also lodge into the surrounding tissues causing degeneration and destruction. 

Current Updates on the DePuy ASR Hip Recall

The DePuy ASR metal-on-metal hip implant was approved in 2005 by the FDA, but soon thereafter both DePuy and the FDA began receiving reports of adverse health events. Some believe that the much less rigorous 510(k) approval process which allows manufacturers to skip clinical trials could be at least partially responsible for the adverse health effects in the thousands of ASR recipients. Following a flurry of complaints, DePuy voluntarily recalled the ASR on August 26, 2010. At present there are approximately 4000 DePuy ASR lawsuits consolidated into an MDL in Ohio as well as a smaller mini-state consolidation in Chicago with approximately 600 plaintiffs and another in California containing 1500 or so plaintiffs. Since California is experiencing so many financial problems, the plaintiffs and their attorneys are expected to face problems in getting a trial setting.

The MDL, or multi-district litigation system is meant to streamline the litigation process, taking advantage of the fact that there are similar allegations from all plaintiffs made against the defendants—in this case DePuy and Johnson and Johnson. The first trial regarding the ASR was scheduled to begin in state court in Las Vegas in mid-December although it has been rumored the case settled prior to trial. Should this be true, it would be a positive precedent for all other ASR lawsuits to follow. The metal-on-metal design came about due to its ability to last significantly longer than the metal-on-ceramic or metal-on-plastic hip implants. Unfortunately, the metal-on-metal design allowed the cobalt and chromium ball and cup to shave off microscopic metal ions into the body, entering the surrounding tissues or even the bloodstream. The FDA recently held a two-day panel to discuss the safety of the metal hip implant. 

Problems with the DePuy Pinnacle Hip Implant: Current Reports

As of this date the Pinnacle metal-on-metal hip implant device manufactured by DePuy has not followed in the recall footsteps of DePuy’s other hip implant, the ASR. While Johnson and Johnson and DePuy vigorously deny that the Pinnacle has any problems—and, in fact, call it the best metal-on-metal hip implant on the market today—many recipients of the device feel it has some of the same flaws as the ASR. Both the Pinnacle and the ASR are manufactured by Johnson and Johnson’s subsidiary company, DePuy. The Pinnacle made its debut in 2002 as the predecessor of the ASR which followed in 2005. The ASR is strictly a metal-on-metal hip implant device while the Pinnacle name includes metal-on-ceramic and metal on polyethylene models as well.

Nearly 150,000 Pinnacle all-metal hip replacements have been implanted compared to 93,000 ASR’s worldwide—approximately half of those in the United States alone. Both the Pinnacle and the ASR all-metal hip implants were approved under the controversial 510(k) FDA approval process. This particular process allows the majority of medical devices to get to market quickly by showing they are substantially comparable to a device which has already gained approval. The process also allows a product to get to market without expensive clinical trials however in some cases the approval process has been predicated on a device which is no longer marketed—even due to poor performance.

Johnson & Johnson Hip Implant Settlement: Filing Deadlines are Approaching Fast

Many recipients of the ASR metal-on-metal hip implant are unaware of a crucial date which is fast approaching. The ASR was approved by the FDA in 2005 then labored under a flurry of adverse reports regarding early failure rates. Finally, on August 26, 2010, DePuy recalled the ASR, citing failure rates of around 12-13%--as opposed to their initial reports of 4-5% failure rates. What this means is that among the 26 states which operate under the two year statute of limitations, there is less than a month left to join in the multi-district lawsuits against DePuy. Of the more than 40,000 recipients of the ASR in the U.S. alone, only about 6,000 of those have joined in as plaintiffs in the DePuy suit. This means there are over 35,000 ASR recipients out there who have yet to come forward.

There may be several reasons for this including the fact that many of these people may be unaware of the recall. Others may be elderly recipients of the metal ASR and are simply chalking their negative health symptoms up to the aging process. It is believed, however that a large number of those who have not joined in the lawsuit have not done so because they are not yet experiencing problems, therefore believe they have no rights under the current lawsuit. It’s important that this group of people be aware that the actual failure rate of the ASR has been estimated at 50% at six years and 80% at eight years. Considering the ASR metal-on-metal implant has only been on the market since 2005 you can see that the likelihood of thousands more recipients having serious problems from the device is huge. 

U.S. Drug Watchdog Urges Pinnacle Hip Implant Recipients to Come Forward

Over 130,000 Americans received a DePuy Pinnacle metal-on-metal hip implant between the years of 2005 and 2010. Although its counterpart, the DePuy ASR XL hip replacement system was recalled in 2009, the Pinnacle, while employing the same construction methods and materials, has not been recalled. Because of the recall of the ASR, there is mounting concern that the Pinnacle may also expose recipients to the dangers of metallosis or metal toxicity. The U.S. Drug Watchdog has stated their goal of reaching each and every one of the recipients of the Pinnacle implant to ensure none who have suffered harm are left behind.

Although only about a thousand people have come forward to date, the U.S. Drug Watchdog believes those numbers will grow rapidly, reaching well over 100,000. When the victims are properly identified they will then be provided access to the most knowledgeable attorneys who possess a thorough background in the intricacies of the metal hip implant. The objective of the U.S. Drug Watchdog is to ensure every person who had their health harmed because of a metal-on-metal hip implant receives appropriate compensation for failure of the implant.

New Data From Britain About DePuy ASR Acetabular Hip Replacement Devices

By Independent Staff Writer 

Is Johnson & Johnson Telling the Truth About the Failure Rate?
Johnson & Johnson claimed the failure rate was 13% when it recalled the DePuy product in 2010, according to its press release. Johnson & Johnson started using the device in the United States in 2005 and based its failure rate on five years of research.  However, England has a hip registry dating back well before 2005.
This week a report by The British Orthopedic Association revealed the DePuy ASR XL hip replacement unit fails as often as 49% of the time. This is an astounding four times what Johnson & Johnson reported stated when it recalled the device last year.

Dr. David Beverland, an Irish orthopedic surgeon who does massive numbers of hip and knee replacements reported that he started implanting the ASR devices in his patients in September 2004 and stopped in May 2007. He declined to say why he stopped the implants, but reported that 32% of his ASR XL patients have been or will need a second hip replacement (revision) and 44% are symptomatic. Only about 22% of his ASR XL patients seem to have achieved a good result and three of his patients died after receiving the implant. This is a serious problem for the defense since Beverland has been a major consultant and product champion for DePuy.
Here are the real facts:

Bone deterioration is associated with disease; soon, it may also be linked to the DePuy ASR XL Acetabular System. And for good reason.

By Independent Staff Writer

As we try to describe the reasons the DePuy ASR XL Acetabular System present such a danger to your health, we occasionally use terms you may be only vaguely familiar with. This is an ongoing series of articles on the medical terms related to the DePuy hip recall and hip revision surgeries.
When undergoing hip surgery, there are generally two options for a hip implant: cemented and uncemented. Cemented implants, which involve attaching the implant directly to the surrounding bone by means of a specially constructed bone cement, have been used since the 1960s. Uncemented implants were introduced in the 1980s. The ASR XL Acetabular System is an uncemented implant.
The idea behind an uncemented implant is that healthy bone can grow into its surface, thus holding the implant in place by means of the body's own materials instead of a foreign cement. Medical professionals hoped that this design would mean the patient could have a more active life since the concern of gradually wearing away the cement would be eliminated. Cementless total hip replacements are recommended for younger, more active patients and have shown, so far, better results in long-term studies.
Obviously, healthy bone is essential for an uncemented hip implant. Without healthy bone growth, the hip implant will not be secured into the rest of the skeleton and will not function as a replacement for the removed hip.

Evidence is showing that the DePuy ASR XL Acetabular System may cause serious bone deterioration in a number of ways. One of the most significant is osteolysis, which occurs when the body reabsorbs bone as part of an autoimmune response. Osteolysis has been noted as a side effect of many total hip replacement systems; the more debris that is released into the body, the more common osteolysis becomes. Metal-on-metal hip implants were thought to have less likelihood of debris because they are made of harder materials, but the ASR XL Acetabular System's poor design caused significant friction and a great deal of metal debris, raising the risk of osteolysis.

The ASR Acetabular System falls far short of other total hip replacement systems. Here's how.

By Independent Staff Writer

In a previous article we wrote on bone deterioration, we discussed how the bones of your hip are constructed and how a hip implant strives to mimic the qualities so that you can maintain a normal range of movement and a fairly active life.

In this article, we'd like to show you how the ASR XL Acetabular System was constructed - and why it fell so short of what hip implant patients needed to give them back their previous quality of life.

What a Hip Implant is Up Against

Any hip implant is going head-to-head against the natural construction of your body, which is no easy feat. What we think of as our hip is actually two bones: the acetabulum (also called the hip socket) and the femoral head, which is the rounded top of your femur (the main bone that runs the length of your thigh).

As you can see, the two bones of your hip are actually attached to each other securely by two ligaments. The shorter ligament at the center of the femur head is the transverse acetabular ligament, while the longer ligament that runs from the ilium down to the femur itself is the iliofemoral ligament.

These ligaments, along with the cartilage surrounding the hip joint, are the reason your hip doesn't dislocate on a regular basis. The iliofemoral ligament in particular is extraordinarily strong - in fact, the strongest ligament in the human body - and when you are standing or sitting, this ligament flexes or releases to allow a range of movement without letting the hip move out of the socket.

For its part, the transverse acetabular ligament and the surrounding cartilage make up the acetabular labrum, whose purpose is to deepen the hip socket so that the head of the femur can't slip out. The deeper the hip socket, the more secure the femur bone becomes and the less likely your hip will dislocate.

When your natural hip is removed to make way for a hip implant, neither of those ligaments is in place, and the cushion of cartilage is removed to make way for an artificial replacement. Removing the labrum means that your hip is 92% more likely to suffer contact stresses and 40% more likely to allow the femur and acetabulum to touch.

As you can see, your hip is a sophisticated and well-constructed mechanism, and it is extremely difficult to create a man-made replacement for it. Let's take a look at some of the best attempts available in the form of conventional hip replacement and total hip replacement systems, including the ASR Acetabular System. 

How the ASR XL Acetabular System Causes Bone Deterioration...And what it means for your future hip revision surgeries.

By Taylor Lindstrom

When DePuy issued their hip recall, they offered to pay for the revision surgery needed to replace the faulty hip with a new implant. They appear to believe this is the full extent of their responsibility in repairing the damage they've done to thousands of people who had a hip replacement implanted in their bodies.

It's not enough. Because the damage the ASR XL Acetabular system caused doesn't end when the hip is removed. It's only just beginning. 

How Your Hips Work

If this were an after-school special, we'd show you a few clips at this point: Elvis shaking his hips on stage back in the day, or a ballet dancer extending her leg over her head. The after-school special would be missing the point, however - your hips are essential to nearly every movement you make. You use them every time you stand, sit, crouch, or lean over. You use them getting into and out of cars, climbing up the porch steps to your front door, even just standing there. 

A hip is a little bit like oxygen. You don't notice how essential it is until it's gone.

There's a reason you barely notice your hip's contribution to your everyday movements: your body has constructed it more or less perfectly. The hip bone is a portion of your pelvis, and it has a rounded cup-shape in its center into which the top of your femur bone fits, called the acetabulum.

The top of your femur fits smoothly into the acetabulum and rotates when you move, cushioned by synovial fluid that naturally lubricates the hip joint. When you get a hip implant, the idea is to mimic this natural construction of your hip joint as closely as possible, including the range of rotation, the lubrication, and the way the ball (the head) and socket (the acetabulum) fit together.

How a Hip Implant Works

There are two basic ways of affixing the hip implant to the rest of your skeleton. In both, the top of your femur is sawn off and replaced with an artificial new head, while the hip bone itself is shaved down to accommodate a man-made socket. Essentially, the acetabulum is carved out to the shape of the new socket.

The difference lies in how the new femur head and socket are attached to the surrounding bone. In older patients, the most common tactic is to use a bone cement to attach them. In younger patients, however, the surrounding bone is still versatile and capable of regrowth. Since cement has some serious drawbacks, including the risk that it will shrink or crack over time and the fact that it is not especially secure when it comes to withstanding forceful movements like jumping, another procedure has been developed for younger patients. 

The surgeon recommended a DePuy hip implant to his patient thinking the device was fully tested by the FDA for safety. He was wrong.

By Taylor Lindstrom

A 30-year-old man needs a hip replacement. His surgeon recommends a DePuy ASR XL Acetabular system because its metal-on-metal design is more durable and allows for a more active life. Following the doctor's recommendations, the young man gets the DePuy hip implant.

Then the hip implant fails. The young man is in extraordinary pain. His revision surgery reveals dead tissue and deteriorated bone, making it extremely difficult for his new implant to take hold. He takes a blood test that reveals extremely elevated levels of cobalt and chromium. He is now hypersensitive to metal and the surgeon warns him he may contract early-onset osteolysis.

The young man blames the surgeon for recommending the ASR XL Acetabular system in the first place? But the surgeon isn't the culprit in this scenario; he made the best recommendation he could for his patient. The surgeon is simply another victim of the real culprit: an FDA approval loophole called "substantial equivalence." 

A surgeon has countless medical devices to choose from. In the world of hip implants, he's looking at numerous options. The surgeon naturally wants to give his patients the best implant possible for their situation, so he chooses only FDA-approved devices that have been rigorously tested for safety.

Or so he thinks. 

Does an FDA Endorsement Guarantee Hip Implants' Safety?

The FDA has two processes for approving a new medical device: the premarket approval process,, and the premarket notification approval process. Similar as their names are, there is a world of difference between those two processes.

In the case of the patients who received an ASR XL Acetabular system, it may have been the difference between an improved quality of life with a working hip implant - or a drastically reduced quality of life with a faulty one. 

The premarket notification process is also known as the 510(k) process, and it includes the loophole of "substantial equivalence." The 510(k) process allows a product to go directly to market without full clinical testing if the manufacturer claims the medical device is "substantially equivalent" to another device already on the market.

According to FDA documents, a substantially equivalent product is one that is created for the same intended use as the previously approved products; has the same design, materials and technology; and raises no new concerns about safety or effectiveness.

Substantial equivalence was designed to prevent the 2-3 year waiting period for testing. If one hip implant is so similar to another device that it could be expected to get the same test results, what was the point of testing it?

One might argue "safety," but one would be naive to do so. Medical device companies pushed for the substantial equivalence loophole for an entirely different and far less altrustic reason: profits. Every year spent in testing is a year that hip implant isn't on the market earning money for the company.

A Pyramid Built on Sand

For Johnson & Johnson and its subsidiary DePuy, the priority was on products, not patients. They claimed the ASR XL Acetabular System was "substantially equivalent" to no less than three other devices already on the market that had been tested for safety.

Every part of that statement would prove to be inaccurate.

Companies are allowed to claim that their new product is substantially equivalent to more than one other product. For example, since they have to show that they have the same materials and technology as a previously approved product, a company might show that they used the same materials as one product and the same technology as another.

For the ASR XL Acetabular system's 510(k) application, DePuy cited three different previously approved products saying that the ASR system was "substantially equivalent"-at least in part-to all three.

By this argument, you could get a safety approval from the FDA for a flying car with submarine without ever testing it - after all, it is "substantially equivalent" - at least in part - to an airplane, a car, and a submarine. What on earth would be the point in testing it again when the basic principles have already been proven safe? 

The loophole gets even more absurd: companies are allowed to base their claims of "substantial equivalence" on products that were approved under the same 510(k) process.

One of the devices DuPuy used was approved with one device-that had been approved through another device-that had been approved through a third device-that was approved because it was substantially equivalent to a product grandfathered into the system prior to 1976. 

Essentially, DePuy was claiming that their product was substantially equivalent to hip replacements manufactured before the FDA was ever in place

 

Not a single hip implant in this chain of FDA was ever subjected to clinical trials before it was allowed to go to market. Even if it had been, it seems laughable that a hip implant "substantially equivalent" to a series of pre-1976 implant could ever make it through the FDA. Has technology developed so slowly that the best implants on the market are based on designs from 40 years ago?

Put it into perspective: the ASR XL Acetabular system was marketed to younger people who needed a longer-lasting, more durable hip replacement. That means many of the recipients got a hip implant based on a design older than they were.

Only 10% of applications submitted under the 510(k) process are ever returned with a request for clinical trials. That means that 90% of the Class III hip implants available today were never tested in a clinical setting before being marketed to the public. 

The DePuy ASR XL Acetabular hip replacement system was FDA approved - which might be more cause for worry than relief.

By Lacy Boggs

Since 1976, all medical devices must be classified and approved by the U.S. Food and Drug Administration (FDA) before they can be legally marketed to the public. It is the fond belief of many Americans that FDA approval is a ringing endorsement of a product's safety, a guarantee that the device has been tested and re-tested by professionals who are presumably trained to put the device through all kinds of rigor to triple-check its safety and effectiveness before allowing it anywhere near our fragile human bodies.

It is, as we say, a fond belief, but not an accurate one. It seems that many medical devices - including the recently recalled DePuy ASR XL Acetabular System - are given an FDA approval and subsequently placed inside people's bodies without ever going through a single test at the FDA. 

The FDA department responsible for the regulation and review of medical devices is the Center for Devices and Radiological Health (CDRH). CDRH divides medical devices into three classes: life-sustaining, life-supporting or implantable devices are designated as Class III.

Hip replacements, including the ASR XL system, qualify as a Class III device and are considered high risk to the patient's health. 

Class III devices can be approved by the FDA through one of two processes. The first, the premarket approval process (PMA) is more or less what we think of when we imagine our device being tested by the FDA: an extensive review including rigorous clinical trials that show it to be safe for use in humans. The PMA is quite detailed, lengthy, and expensive, usually costing the manufacturing company upwards of $250,000 and taking as much as two years to complete.

A quarter of a million is a large chunk of change - but thankfully for companies with a firm eye on their bottom line, there's always the second FDA approval process.

The premarket notification approval process, also known as the 510(k) approval process, is a sort of shortcut to approval that lowers the price point considerably - and also, conveniently, doesn't involve any pesky testing that might reveal a flaw in the product that would then have to be revamped and retested for another quarter-million. 

The 510(k) process basically pre-approves any product that is deemed "substantially equivalent" to another product already legally approved for sale. It costs less than $5,000, requires no clinical trials, and only takes an average of 3-6 months to complete. It's a good shortcut for products that are essentially identical to their forebears. After all, it hardly makes sense to waste the FDA's time when they could be helping get new, innovative, life-saving products to market. But what's to stop companies from claiming their products are "substantially equivalent" to other FDA-approved devices even if they're not remotely the same?

What, indeed

The ASR XL Acetabular hip replacement system got its seal of approval from the FDA using the 510(k) process, claiming that its product was substantially equivalent to other hip replacement devices already on the market. The FDA official in charge of approving the device would have gone through a checklist that included the following questions (simplified; the actual document is fairly dense):

• Does the new product treat or solve the same problems as previously approved products?
• Does the new product have the same design, materials, and energy sources as previously approved products?
• Could any new characteristics or combinations of characteristics affect safety or effectiveness? 

DePuy ASR Hip Implants Risk

Cobalt Poisoning: DePuy ASR Hip Implants Are a Serious Risk 

Home | Personal Injury | DePuy Hip Recall | Traffic Tickets | Family Law | Criminal Defense |Get Informed

A person with 1 microgram of cobalt in their bloodstream has nothing to worry about.  Someone whose blood contains more than 25 micrograms has cobalt poisoning. And a patient whose blood contains more than 100 micrograms? Probably has a DePuy ASR hip implant. As more and more patients who received DePuy ASR Acetabular hip replacement systems ask their doctors for blood tests, the numbers of people who have extraordinarily high levels of cobalt in their bloodstreams become staggering. Several of our own clients have received the worrying news that their cobalt levels are far above normal, and at least one doctor has published a case study of two DePuy hip implant recipients who have cobalt levels that are 100 to 500 times normal. How Much Cobalt Is Normal?  If you go to a doctor and get a blood test, the amount of metal (including cobalt) in your bloodstream will be calculated in micrograms per deciliter. A healthy person has approximately 0.019 micrograms per deciliter - about one microgram for their entire body. The metal in your bloodstream only presents in very, very small amounts; someone with normal cobalt levels could gather all the cobalt in their system together and come up with an amount smaller than a grain of sand. Even at highly toxic levels, the actual amount of cobalt looks very, very tiny. 0.5 micrograms per deciliter of cobalt is considered toxic. That's about five grains of sand in a giant bucket of water. Seems small - but those tiny grains of metal can throw the entire chemistry of your body wildly out of order. In Britain, there are regulations for keeping close observations on patients who have metal-on-metal bearings in any hip implants, including the ASR hip implants. At cobalt levels of 0.7 micrograms per deciliter, patients must be kept under observations. Symptoms at those levels include hip pain, dying tissue, and pseudotumors - masses under the skin. Generally doctors recommend revision if a patient with a hip implant has a cobalt concentration of 1.9 micrograms/deciliter or above. Revision isn't suggested until cobalt concentrations are one hundred times the mean average - even though levels are considered toxic at twenty-five times the average. One patient with severe cobalt poisoning had levels of 6.6 micrograms/deciliter. That's nearly three hundred and fifty times the mean average. The dangers of cobalt levels so high were quite apparent: in addition to hip pain, the patient showed declining cognitive function, was losing control of his senses like hearing and sight, suffered from seizures, heart failure, and multiple other problems. The amount of cobalt that patient had in his blood was still small enough that it wouldn't have filled a teaspoon. But the damage was great enough to threaten his life. What is Cobalt Poisoning? Cobalt is one of the many metals that is found naturally in the body, but as with all other metals, in excess amounts it becomes toxic and leads to many harmful and potentially permanent side effects. Cobalt poisoning has caused cardiomyopathy, hypothyroidism, and neurological damage as well as impairing the senses. It can cause neuropathy, seizures, blindness, headaches, and liver damage. Cobalt has also been linked to cancer. For DePuy hip implant recipients, it can also mean that future hip revisions have a lower chance of success. Excess amounts of cobalt in the bloodstream lead to metal sensitivity and metallosis, which can seriously damage surrounding tissue and make a second implant less likely to succeed. Doctors Unaware of Risk  For many patients with DePuy ASR hip implants, the symptoms of cobalt poisoning either go unnoticed initially or are chalked up to other pain and problems related to the hip implant failure. For example, a patient might have deteriorating mental function, mood disorders, or vertigo -  but if the patient is also in a great deal of pain because the hip implant is failing, it is very possible that he might assume the other symptoms are related to his pain and will go away if he has a revision surgery. Meanwhile, doctors who are fully aware that DePuy ASR XL Acetabular System is failing at inordinate rates may recommend a revision surgery to solve problems of pain and inflammation. Those doctors may not know that the friction of the hip implant is releasing excess amounts of metal ions into the bloodstream and causing potential problems with far more long-reaching effects. A patient could walk out of surgery with heavy metal poisoning - and not be aware until the symptoms become extreme enough to return to the hospital. What Should You Do?  If you have a DePuy ASR Acetabular hip implant and are concerned about cobalt poisoning, see your doctor as soon as possible to discuss your options and express your concerns. Our medical crib sheet for DePuy ASR hip implant patients can give you some guidance on questions you may want to ask your doctor and tests you may wish to request.

Why Depuy Hip Was Recalled

Chromium Poisoning Just as Dangerous as Cobalt Poisoning 

Home | Personal Injury | DePuy Hip Recall | Traffic Tickets | Family Law | Criminal Defense |Get Informed

Early this year, DePuy issued their recall for the ASR XL Acetabular System sold in the United States. Doctors began recommending revision surgery to those of their patients who reported pain or an overall failure of the DePuy hip implant. In many cases, the doctor was wise enough to run a blood test to determine whether there was excess metal in the bloodstream, as many medical studies have shown that elevated levels of metal are common for patients with metal-on-metal hip implants. Patient after patient with the ASR Acetabular DePuy hip implant began turning up with cobalt and chromium levels that were well over 100 times normal. Cobalt poisoning has been getting a great deal of attention and for good reason: the symptoms of cobalt poisoning include many serious side effects including neurological (brain) damage, heart irregularities, and seizures. Cobalt poisoning has also been linked to cancer. It's small wonder that many people, when they first learn that the DePuy hip implant leaks metal ions into the body, are primarily concerned about cobalt poisoning. However, chromium poisoning is equally dangerous. And the symptoms are just as troubling. What is Hexavalent Chromium?  When discussing chromium poisoning, the most significant problems have been linked to a particular compound, hexavalent chromium (Chromium (VI)). Hexavalent chromium is the agent that turned up in the water supply of the California town of Hinkley, later made famous by Erin Brockovich's activism work. Many people remember the Erin Brockovich story - if not for the event itself, certainly for the award-winning movie based on it. They remember that there were many cases of cancer in the town; 196, to be precise. Few of them remember that the problem with the water was hexavalent chromium. Hexavalent chromium has been deemed a cancer-causing agent by the World Health Organization, which means that both chromium and cobalt can elevate a DePuy hip implant patient's cancer risk. In fact, studies show that elevated levels of any heavy metal increase the risk of cancer. Our research indicates that hexavalent chromium is the type of chromium being released by the ASR Acetabular system; it degrades in the body into trivalent chromium, or Chromium (III). Anywhere from 18-30% of a typical metal-on-metal implant is composed of chromium; we do not have current numbers on the amount of chromium included in the DePuy hip implant. Patients with elevated chromium levels show similar symptoms as those with elevated cobalt levels. There are notable differences; cobalt poisoning can cause cardiomyopathy, for example, while elevated chromium levels do not appear to cause heart problems but can cause problems with the reproductive system. The table below gives an overview of the symptoms shown by patients with elevated chromium levels vs. those with elevated cobalt levels. If a particular type of chromium or cobalt has been specifically linked to a symptom, it is noted in parentheses next to the symptom. For example, mutated DNA is noted as being linked specifically to Chromium III.

Even if you have elevated levels, you may still not have chromium or cobalt poisoning; slightly elevated levels are normal for patients who have metal-on-metal hip implants and among the doctors we've consulted, they do not consider slightly elevated levels to be cause for alarm. For those DePuy hip implant patients who have presented with 100 and 500 times the normal level of these two metals in their systems, however, doctors are quite concerned. Cobalt and chromium can both be retained in the bodily tissues for a long period of time, and if the body is subjected to excess levels, it will have a more difficult time processing the metal ions through the normal elimination process, especially if the kidneys are damaged - a problem sometimes caused by chromium poisoning. Little research has been done on the long-term effects of elevated metal ion concentrations. When speaking to your doctor, we have a medical crib sheet that may be prove useful if you are uncertain what to ask about or worried you may forget important questions. We would also highly recommend you read this article on DePuy trying to get patients to agree to give the company access to their medical records; if you are thinking of pursuing a legal case against DePuy, signing away your medical records can be severely detrimental to your case. If you have received a DePuy hip implant and are concerned about the effects chromium and cobalt poisoning may have on your health, please give us a call at 1-800-730-7607 or send us an email through our online system. We're here to answer your questions and help you build a case against DePuy if you think that is the best course of action for you.
