CT angiogram, echocardiogram and thyroid function test results were all normal and she had no previous history of depression or dementia. Both chromium and cobalt are metals that, over time, can poison an individual who has too much of them built up in his or her body. Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. A 2017 study in BMC Psychiatry looked at ten cases of metal-on-metal hip replacements. That is eight times the failure rate of most orthopedic implants. Metallosis is a type of metal poisoning that can occur as a side effect of joint replacement devices with metal components, such as metal-on-metal hip replacements or other metal implants. The soft tissue destruction is often irreparable, resulting in many patients doing poorly after revision procedures,” per The BMJ. Chromium Chromium poisoning is as dangerous as cobalt poisoning. The DePuy knee is made from a combination of metal and plastic parts including a Cobalt-Chromium-Molybdenum alloy. Patients with elevated chromium levels often show similar symptoms as those with elevated cobalt levels. Hip replacement surgery is a viable option for people who suffer from limited mobility due to hip pain. On Jan. 28, 2013, his serum cobalt level was 2.7 mcg/L, chromium was 2.3 mcg/L, and all of his symptoms resolved. Her serum cobalt level had reduced to 60 nmol/L. The other danger for cobalt poisoning is that it could mimic other conditions. It happens when there’s friction between metal surfaces. In the presence of persistently elevated metal ion levels and symptoms consistent with metal toxicity, once other causes have been excluded, revision hip replacement is the only method available to decrease the ion levels. The first is a skin reaction called dermatitis. accepted. Learn about the symptoms, sources, diagnosis and treatment for heavy metal poisoning and toxicity. Symptoms of cobaltism have been previously described when cobalt was used to treat refractory anaemia in patients 40 years ago.7 The term “arthroprosthetic cobaltism” has been coined to describe these manifestations in patients with joint replacements.3. The other danger for cobalt poisoning is that it could mimic other conditions. Metallosis is the putative medical condition involving deposition and build-up of metal debris in the soft tissues of the body.. Metallosis has been known to occur when metallic components in medical implants, specifically joint replacements, abrade against one another. Metal allergy, a little-known problem, caused systemic pain, severe weakness and fatigue for a woman after knee replacement. DePuy’s negligence does not end there, either. The worry is that the metal-on-metal contacts in the hip replacements grind off tiny metal molecules -- chromium and cobalt ions -- that might be toxic. These devices are made from a blend of several metals, including chromium, cobalt, nickel, titanium and molybdenum. Metallosis knee replacement Footnote: 74-year-old woman who presented to her general practitioner after experiencing 2 years of worsening metallic skin tattooing, pain, and swelling to her left knee. Patients with elevated chromium levels often show similar symptoms as those with elevated cobalt levels. They knew it was dangerous. Cobalt poisoning is an intoxication brought on by having too much cobalt in the body. She had mild groin pain but otherwise no symptoms related to her hip. Cobalt Poisoning From a Hip or Knee Replacement Could Drive One to Suicide ... Dr. Cobalt chromium poisoning is a risk for anyone with a metal on metal (MoM) hip replacement. They knew it would fail. We are finding cobalt poisoning in too many patients with metal-on-plastic and metal-on-ceramic hips. Because of this, metal-on-metal hop replacements with chromium and cobalt were able to enter the market without the rigorous testing required for new Class II and Class III devices. She also had a continuous metal taste in her mouth and complained of severe headaches, anorexia and weight loss. The ASR metal cup and head were removed and the stem retained. The tragedy, however, is that patients with extreme cases of cobalt toxicity may have injuries that are too severe to be reversed. Provenance: Not commissioned; externally peer reviewed. But fans are asking when that hip replacement actually happened. DePuy used the same 510(k) submission process that so many manufacturers use. The biggest culprit for toxicity seems to be cobalt-chrome but there is no generally accepted threshold beyond which serum or blood concentrations of cobalt and chromium are known to be toxic8. The most notable difference is that cobalt poisoning can cause cardiomyopathy while elevated chromium levels do not appear to cause heart problems but can cause problems with the reproductive system. The most notable difference is that cobalt poisoning can cause cardiomyopathy while elevated chromium levels do not appear to cause heart problems but can cause problems with the reproductive system. Immediately before the revision surgery, the patient’s serum cobalt level was 258 nmol/L, with a normal level of chromium (88 nmol/L). Cobalt chromium poisoning is a risk for anyone with a metal on metal (MoM) hip replacement. We report two Australian patients with possible cobalt toxicity related to metal-on-metal total hip replacements. In this condition, a skin rash that looks like eczema can occur. Case Studies. This blog post provides general information to help the reader better understand regenerative medicine, musculoskeletal health, and related subjects. Knee replacement surgery is a very successful surgery; the vast majority of people who undergo this treatment for severe knee arthritis are satisfied with the surgery. It is a far more common side effect than you might think, and one that should have been anticipated by DePuy long before they started selling this defective medical device to patients. The silver lining to cobalt poisoning is that the symptoms and damage, if caught in time, may be completely reversible. Some symptoms of titanium implants can be an autoimmune response or allergic reactions that can include inflammation, blistering and a rash around the implant site. They can cause damage to the respiratory system, the kidneys and the heart. Of the 48 patients, 20 died as a result of their heart disease. A 60-year-old male professor of engineering presented in January 2011 with systemic symptoms, for follow-up after a right total hip replacement with a DePuy ASR XL Acetabular Hip System prosthesis 4 years previously. A multitude of harrowing symptoms soon followed. When metals build up in a person’s blood and tissues, they can cause serious injuries. The doctor chose to use a new type of devise for the replacement. Cobalt Poisoning: DePuy ASR Hip ... As more and more patients who received DePuy ASR Acetabular hip replacement systems ask their doctors for blood tests, ... the symptoms of cobalt poisoning either go unnoticed initially or are chalked up to other pain and problems related to the hip implant failure. We believe our patients’ symptoms were related to their elevated cobalt levels, resulting from cobalt leaching out of their hip prostheses. We will be measuring his cobalt levels, as these two go in tandem for hip replacement patients. Ross Crawford has received consultancy fees and royalties from Stryker, a manufacturer of joint replacement prostheses. Metals poisoning is called metallosis. The direct effect of cobalt on cells has recently been explored. Still, executives in Johnson & Johnson’s DePuy Orthopaedics unit kept selling the A.S.R. The most common symptoms associated with metallosis include: Health problems (cardiomyopathy) like heart failure; Nerve problems (neuropathy) He had significantly improved exercise tolerance and was able to walk without restriction. The doctor chose to use a new type of devise for the replacement. In 1966, a curious case of cobalt poisoning occurred in Canada. The patient’s original hip replacement had been done in 2006 with an ASR (articular surface replacement) hip prosthesis (ASR XL Acetabular Hip System [DePuy Orthopaedics, Warsaw, Ind, USA]), comprising a large-diameter metal (cobalt and chromium) cup with a large modular metal head on a titanium Corail stem (Box). Trucks and Guardrails – How Much Protection Do They Really Offer. He has over 25 years of experience helping injured people fight back against corporations, hospitals and wrong-doers. Finally the doctor replaced the devise with one that had already proven reliable. He had no hip symptoms, but an x-ray showed quite marked bone loss around the acetabular component. Another rare form of cobalt poisoning is from a hip replacement. At review, she had neurological symptoms, including cognitive decline, memory difficulties and depression, which had been present for 7 months since a cerebrovascular episode. After revision surgeries, the patients’ symptoms improved.

Almost 3 years later, it was replaced by metal implant containing cobalt, chromium, and titanium. MarketWatch believes that “The global major orthopedic joint replacement implants market is expected to grow from $16.6 billion in 2017 to $20.1 billion in 2022.”. Almost every metal-on-metal hip implant is made out of cobalt and chromium (another dangerous metal). In addition, if the cobalt toxicity is from a metal hip implant, there may be additional symptoms related to chromium poisoning. Her acetabulum was revised with an all-polyethylene cemented cup and the head was changed to a ceramic one. However, some of these metal-on-metal prostheses have not lived up to the promise of increased durability. Metallosis is a formal poisoning caused by exposure to metal that is often a side effect that occurs after a metal joint replacement device has been implanted during hip or knee replacement surgery.

The patient’s symptoms included fatigue, rashes, spasms of the left thigh and gluteal muscles with standing and progressive hip pain, “but he wasn’t thinking, ‘My hip … Cobalt toxicity can lead to devastating effects, but if it is caught early enough and revision surgery is performed to remove the metal prosthetic, damage can be reversible. Since the advent of proper brewing techniques “beer-drinkers cobalt toxicity” is also a relatively rare occurrence [21-23]. Both patients were treated for osteoarthritis with a DePuy ASR (articular surface replacement) XL Acetabular Hip System prosthesis, which contains cobalt and chromium, and which has recently been recalled from the market. Another study in 1994 reviewed the “dissemination of cobalt and chromium ions into lymph, liver, and spleen,” per The BMJ (formerly the British Medical Journal). According to DePuy’s internal estimates, [the A.S.R. Publication of your online response is Three different case studies of cobalt toxicity after hip replacement surgery were presented within 10 days of each other in early 2014. A good, close friend had hip replacement a few years back. She had particularly noted difficulty in remembering names and registering information (both written and aural), headaches and cerebellar signs (ataxia and dysdiadochokinesis). In particular, cobalt poisoning can lead to: The silver lining to cobalt poisoning is that the symptoms and damage, if caught in time, may be completely reversible. metal-on-metal hip replacement was] projected to fail within five years in about 40 percent of patients who received one. A computed tomography (CT) scan at this time showed a hypodensity in the right anterior commissure, although it could not be confirmed whether this represented a lacunar infarct or a perivascular space. Metallosis is a medical condition that involves metal debris building up in the soft tissue, usually around the site of a metal-on-metal implant, such as a hip replacement or knee implant. He has been certified by the American Board of Professional Liability as a specialist in Medical Malpractice Law which is recognized by the South Carolina Bar. Metallosis is a type of metal poisoning that can occur as a side effect of joint replacement devices with metal components, such as metal-on-metal hip implants or some knee implants. Hip replacement patients should be relatively pain-free three months after surgery. Cobalt poisoning can also occur from the wear and tear of some cobalt/chromium metal-on-metal hip implants. She had been admitted to the stroke unit and treated with ongoing clopidogrel. The friction releases tiny metal particles into your bloodstream that could trigger a hypersensitive immune response in your body. Many metal-on-metal (MoM) total hip replacement implants have been recalled due to high failure rates. This type of implant is an artificial hip socket that is created by fitting a … Even though extreme pain is often associated with metallosis, it is not necessarily the indicator that tissue damage has occurred from the poisoning condition. The devise dislocated at will several times and he developed cobalt poisoning. The neurological symptoms that occur with cobalt metal poisoning include: tremors Neurologic dysfunction: There are various neurotoxic symptoms described in patients with presumed cobalt toxicity, including hearing loss, tinnitus, optic nerve atrophy, visual impairment, convulsions, vertigo, headaches, tremors, polyneuropathy, incoordination, cognitive decline, and depression. DePuy executives discussed ways of fixing the defect, the records suggest, but they apparently never did so. These range from [a] 21% revision rate at 4 years (potentially rising to 35% if all currently known painful implants progress to revision) to 49% at 6 years for the ASR XL device. Blood levels. Some of the hip replacement parts can cause cobalt to leak into the bloodstream, causing symptoms similar to toxic levels of cobalt ingestion. Effects of cobalt on the thyroid can cause fatigue, weight gain, and other thyroid dysfunctional symptoms. Other devices have a revision or impending revision rate of 12 – 15% at 5 years.2, An additional problem with metal-on-metal bearings is that they release a variety of metal ions into local tissue and the general circulation, with chromium being the most widely reported of these. Symptoms include: * fever higher than 100 degrees F * shaking * chills * drainage from the surgical site or redness * swelling * tenderness Another rare form of cobalt poisoning is from a hip replacement. This was the result of a hip replacement she had undergone several years prior. The concentration of cobalt in the joint fluid was 4218 nmol/L and chromium was 217 000 nmol/L. The journal also explained that as far back as 1996, “patients with metal-on-metal hips found to be at increased risk of cancer compared with those with metal-on-plastic hips.”. In less than 1 percent of joint replacement … Any of these symptoms can be signs of cobalt poisoning. DePuy knew. Cobalt poisoning is an intoxication brought on by having too much cobalt in the body. Case details: A 56-year-old male patient underwent total hip prosthesis, with a ceramics-on-ceramics implant. Metallosis is a formal poisoning caused by exposure to metal that is often a side effect that occurs after a metal joint replacement device has been implanted during hip or knee replacement surgery. The city is home to western-trained orthopedic surgeons specializing in hip and knee replacements. Cobalt poisoning can manifest with symptoms of varying degrees of severity and can even cause death. What Dr. Tower experienced – what so many patients have experienced – is the effects of cobalt poisoning. Cobalt poisoning symptoms. Both patients were treated for osteoarthritis with a DePuy ASR (articular surface replacement) XL Acetabular Hip System prosthesis, which contains cobalt and chromium, and which has recently been recalled from the market. Of course it will. We thank the patients for allowing us to publish details of their cases. Cobalt, titanium and other metals in hip replacements can cause metallosis, or metal poisoning. Besides the symptoms associated with other forms of metallosis, cobalt toxicity can cause patients to suffer from fever, inflammation, and low thyroid levels. Cobalt; Poisoning; Literature review; Neurotoxicology;Cobalt poisoning; Beer drinkers; Cobalt cardiomyopathy Cobalt Chromium Metal Poisoning from Hip Replacements. He is shown biking around Anchorage, Alaska, where he lives and practices. The silver lining to cobalt poisoning is that the symptoms and damage, if caught in time, may be completely reversible. Her serum cobalt level was 410 nmol/L (reference range, 0–20 nmol/L) and chromium level was 240 nmol/L (reference range, 0–100 nmol/L). Chromium Chromium poisoning is as dangerous as cobalt poisoning. The important lesson from this case is the need to identify symptoms of cobalt toxicity early in patients with prior hip arthroplasty. You When Dr. Tower learned about DePuy Synthes’ new metal-on-metal hip replacements, marketed specifically to people with active lifestyles, he decided that was the right choice for him. Your doctor will perform a blood test to confirm whether you do indeed have metallosis. The A.S.R.’s flaw caused it to shed large quantities of metallic debris after implantation, and the model failed an internal test in 2007 in which engineers compared its performance to that of another of the company’s hip implants, the documents show. An acceptable upper rate of failure of hip prostheses is considered to be below 1% per year, with the vast majority of implants studied by the NJRR falling well below this failure rate.1 The ASR prosthesis originally implanted in both patients reported here has recently been withdrawn from the market, after about 100 000 were implanted worldwide. Prosthetic joint infection (PJI) is a serious complication that “leads to severe pain, poor function, reduced quality of life, and even death.”, Tissue and bone damage may also occur: “adverse reactions to metal debris from metal-on-metal implants are associated with destruction of soft tissue (muscles, tendons, neurovasculature) as well as bone. On last night's 'Grey's Anatomy,' Richard Webber was diagnosed with cobalt poisoning due to a hip replacement. 1539 Health Care Drive When the metal parts rub against each other, they release microscopic metal particles into the blood and surroun… of publication, Information for librarians and institutions.

At 8-week follow-up after the revision surgery, the patient reported significant improvement in his energy levels and a decrease in muscle pains. Although cobalt toxicity is a relatively rare occurrence it should still is noted as a complication of total knee and hip replacement surgical procedures especially when a cobalt alloy is used as the replacement graft. The devise dislocated at will several times and he developed cobalt poisoning. There are over 28 different known isotopes for cobalt including some that are radioactive. Treatment for swallowed cobalt: The health care team will treat your symptoms and order some blood tests. Cerebrospinal fluid (CSF) collected at surgery showed a cobalt level of 9 nmol/L and a chromium level of 13 nmol/L (no reference ranges for these in CSF), showing that the ions had crossed the blood–brain barrier. After revision surgeries, the patients’ symptoms improved. Total hip replacement is generally a successful operation, with a long clinical history of good outcomes. The tragedy, however, is that patients with extreme cases of cobalt toxicity may have injuries that are too severe to be reversed. In addition, if the cobalt toxicity is from a metal hip implant, there may be additional symptoms related to chromium poisoning. Metallosis is linked to artificial joint replacement devices with metal components, such as metal-on-metal hip and knee implants. Heavy metals like lead and mercury are toxic and can make you sick. Not only will more people need implants, but all the victims of defective implants will require revision surgeries. The Australian National Joint Replacement Registry (NJRR) notes large differences in the performance of different types of metal-on-metal hip prostheses. In 1975, a study was commissioned to review the impact of cobalt on tissues. A revision total hip replacement was performed in March 2011, principally because of her systemic symptoms and elevated cobalt and chromium levels. He had a terrible time. From the New York Times: The company had received complaints from doctors about the device, the Articular Surface Replacement, or A.S.R., even as it started marketing a version of it in the United States in 2005. Increased cobalt levels have been reported to be associated with neurological3,4 (hand tremor, incoordination, cognitive decline, depression, vertigo, hearing loss and visual changes), cardiac (arrhythmias and cardiomyopathy) and endocrine5,6 symptoms. There are over 28 different known isotopes for cobalt including some that are radioactive. Conventional total hip prostheses consist of a metal head that fits into a polyethylene cup. Skin discoloration and joint effusion (arrow) after knee arthroplasty failure, prior to revision surgery. Given the patient’s constellation of symptoms and lack of other significant past medical history, the differential in this case was relatively limited. Cobalt is also component of cyanocobalamin also known as vitamin B12, which is widely consumed. Please refer to our, Statistics, epidemiology and research design, View this article on Wiley Online Library, http://www.dmac.adelaide.edu.au/aoanjrr/documents/aoanjrrreport_2010.pdf, http://www.britishhipsociety.com/pdfs/BHS_MOM_THR.pdf, Conditions subject to the Medical Journal of Australia's editorial discretion.

Reports of patient reactions to these ions have spurred the FDA to order the … A knee infection is a serious condition that needs to be treated by a doctor right away in order to avoid serious and life-threatening complications. His serum cobalt level had fallen to 42 nmol/L. Both patients had metal-on-metal hip prostheses, and both patients’ cobalt levels were reduced after removal of the metal-on-metal prosthesis. She had regained a normal appetite and gained weight, the metallic taste in her mouth had gone, and she had less fatigue and greater energy. The risk to the patient occurs with any artificial hip containing a cobalt component.” Conventional wisdom has been that eliminating the metal on metal contact should eliminate the risk of metallosis, but Dr. Tower at least does not accept this thinking. At the time of surgery, 30 mL of turbid fluid was aspirated from the joint and debridement of metal stained tissue was undertaken. The Data on Cobalt Poisoning and Neuropsychiatric Complications. They knew it had failed the tests. Metallosis, or metal poisoning, is a medical condition involving the build-up of toxic levels of metal debris in the soft tissue of the human body. It happens when there’s friction between metal surfaces. X-rays showed a well fixed, well aligned implant, with mild osteopaenia around the acetabular component. It allowed the company to design a hip replacement based on earlier designs and products (called “predicate devices”), and then claim that their product was “substantially equivalent” to those previous models. Concerns have been raised, particularly in younger patients, that the plastic cup suffers wear and tear with time and may require revision. (This is part of a series, presented by McGowan, Hood & Felder, LLC, titled “Life on The Bleeding Edge: How the FDA Won’t Keep You Safe.” To learn more, please read Part One.). Metallosis, or metal poisoning, is a medical condition involving the build-up of toxic levels of metal debris in the soft tissue of the human body. The tragedy, however, is that patients with extreme cases of cobalt toxicity may have injuries that are too severe to be reversed. Other reported effects of elevated cobalt levels on cells include abnormal lymphocyte function,9,10 chemokine secretion11 and ischaemic changes in rat brains.12 A relationship between symptoms and peak cobalt levels, or the length of exposure to cobalt, has not been established.
