Almost every metal-on-metal hip implant is made out of cobalt and chromium (another dangerous metal). 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). Cobalt Chromium Metal Poisoning from Hip Replacements. The devices are manufactured from blended metals that could include titanium, nickel, cobalt, chromium, and molybdenum. Symptoms include: * fever higher than 100 degrees F * shaking * chills * drainage from the surgical site or redness * swelling * tenderness Case details: A 56-year-old male patient underwent total hip prosthesis, with a ceramics-on-ceramics implant. Trucks and Guardrails – How Much Protection Do They Really Offer. 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. When metals build up in a person’s blood and tissues, they can cause serious injuries. She also had a continuous metal taste in her mouth and complained of severe headaches, anorexia and weight loss. The toxicity of cobalt has long been known. Treatment for swallowed cobalt: The health care team will treat your symptoms and order some blood tests. 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. In this condition, a skin rash that looks like eczema can occur. The Australian National Joint Replacement Registry (NJRR) notes large differences in the performance of different types of metal-on-metal hip prostheses. will be notified by email within five working days should your response be Case 2 The case presented in The Lancet involved a 55-year-old man. Randy is the former President of the South Carolina Association for Justice. 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. See metallosis symptoms after hip replacement surgery 24/7 Free Consult (800)734-4134 Log in Clinically significant effects of cobalt poisoning rarely His chromium level was never elevated. Context: Cobalt intoxication has become more frequent due to the wide use of metal hip 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 implants or some knee implants. A 2017 study in BMC Psychiatry looked at ten cases of metal-on-metal hip replacements. Any of these symptoms can be signs of cobalt poisoning. According to the FDA, metal on metal artificial joints produces shavings when they rub against each other during their normal functioning such as walking. They can cause damage to the respiratory system, the kidneys and the heart. 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 … He developed weight loss, heart, thyroid, and neurological toxicity, with severe hearing loss. Her serum cobalt level had reduced to 60 nmol/L. However many may face a side effect know as metallosis from the hip replacement or a similar side effect called cobalt poisoning. This type of implant is an artificial hip socket that is created by fitting a … 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. However, some of these metal-on-metal prostheses have not lived up to the promise of increased durability. What Dr. Tower experienced – what so many patients have experienced – is the effects of cobalt poisoning. A multitude of harrowing symptoms soon followed. Unfortunately, her story is one lived by the many who cope with neurological issues as a result of cobalt toxicity. metal-on-metal hip replacement was] projected to fail within five years in about 40 percent of patients who received one. Hip replacement surgery is a viable option for people who suffer from limited mobility due to hip pain. of publication, Information for librarians and institutions. Effects of cobalt on the thyroid can cause fatigue, weight gain, and other thyroid dysfunctional symptoms. In addition, if the cobalt toxicity is from a metal hip implant, there may be additional symptoms related to chromium poisoning. He had a terrible time. The authors called for a larger group study to define the prevalence and spectrum of cobalt poisoning due to hip replacement surgery. Of the 48 patients, 20 died as a result of their heart disease. His serum cobalt level had fallen to 42 nmol/L. 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. The cerebrovascular episode had occurred in July 2010, when the patient experienced symptoms consistent with a stroke: dizziness, disorientation, nausea, vomiting and being “off balance on the left side”. In addition, if the cobalt toxicity is from a metal hip implant, there may be additional symptoms related to chromium poisoning. 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. You 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. That is eight times the failure rate of most orthopedic implants. There are over 28 different known isotopes for cobalt including some that are radioactive. 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. The most common symptoms associated with metallosis include: Health problems (cardiomyopathy) like heart failure; Nerve problems (neuropathy) 2 He underwent hip surgery in November 2010 to replace his left hip ceramic implant with a metal-on-polyethylene implant. Others symptoms of Cobalt poisoning are reduced vision and amnesia. There are over 28 different known isotopes for cobalt including some that are radioactive. accepted. Heavy metals like lead and mercury are toxic and can make you sick. A good, close friend had hip replacement a few years back. When the metal parts rub against each other, they release microscopic metal particles into the blood and surroun… 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. 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. In sum, metal-on-metal hip replacements, which have been under review since at least 1975, can lead to: Yet despite all of these risks, DePuy went ahead with developing and manufacturing their metal-on-metal hop implants. We will be measuring his cobalt levels, as these two go in tandem for hip replacement patients. We report two Australian patients with possible cobalt toxicity related to metal-on-metal total hip replacements. June 8, 2018 – San Diego, CA. In 1975, a study was commissioned to review the impact of cobalt on tissues. The medical devices used are often a blend of metals like chromium, nickel, titanium and cobalt. It would seem logical to simply monitor knee replacement patients for raised metal levels, but this is not as simple as it seems. They knew it had failed the tests. Hip replacement surgery is a viable option for people who suffer from limited mobility due to hip pain. The other danger for cobalt poisoning is that it could mimic other conditions. Metal-on-metal hip replacements release metal ions into the bloodstream. These devices are made from a blend of several metals, including chromium, cobalt, nickel, titanium and molybdenum. 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. subject to the Medical Journal of Australia's editorial discretion. Metallosis is linked to artificial joint replacement devices with metal components, such as metal-on-metal hip and knee implants. Cobalt poisoning is an intoxication brought on by having too much cobalt in the body. Cobalt is also component of cyanocobalamin also known as vitamin B12, which is widely consumed. In February 2011, the patient had a revision total hip replacement performed because of his systemic symptoms, in spite of having no hip symptoms. Xinzhan Mao, Andrew A Wong and Ross W Crawford, Email me when people comment on this article, Online responses are no longer available. Within weeks, her skin broke out in boils that would crack open and bleed. Finally the doctor replaced the devise with one that had already proven reliable. There is no way to treat a knee … At the time of surgery, 30 mL of turbid fluid was aspirated from the joint and debridement of metal stained tissue was undertaken. Knee replacement surgery is a common surgery that doesn’t present complications for most people. In the worst cases of cobalt poisoning, a patient may suffer permanent, disabling side effects, including cardiomyopathy (degenerative heart disease), blindness, deafness, memory loss, and more. The doctor chose to use a new type of devise for the replacement. Effects of cobalt on the thyroid can cause fatigue, weight gain, and other thyroid dysfunctional symptoms. Its revision rate reported on the NJRR in 2010 was 6.4% at 3 years when inserted with a Corail stem and 10.9% at 5 years when inserted as a resurfacing.1 Updated guidance from the British Hip Society’s 2011 conference noted a, higher than anticipated early failure rate [in large-diameter metal-on-metal hip replacements]. An individual is exposed to this chemical element via inhalation, ingestion, or dermal exposure and, in general, chronic exposure is required for most of the adverse effects to develop.. The devise dislocated at will several times and he developed cobalt poisoning. 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. X-ray of Patient 1’s right metal-on-metal articulation hip replacement, with well fixed cementless femoral and acetabular implant. ACE is meant to identify a brain disease or associated neurological symptoms caused by elevated levels of cobalt from a metal artificial hip. The soft tissue destruction is often irreparable, resulting in many patients doing poorly after revision procedures,” per The BMJ. There was no metal debris or localised tissue reaction. Conventional total hip prostheses consist of a metal head that fits into a polyethylene cup. Free Consultation - Call (855) 370-2828 - Arnold & Smith helps victims and their families receive compensation for their injuries in Product Liability and Defective Product cases. This went on for a couple of years. We thank the patients for allowing us to publish details of their cases. 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. 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. Patients with elevated chromium levels often show similar symptoms as those with elevated cobalt levels. What is Arthroplasty Cobalt Encephalopathy (ACE)? Because it turns out that anyone who submits to joint-replacement surgery is at risk for developing a condition called arthroplasty cobalt encephalopathy, or ACE, but they may not know it — because the symptoms mimic those of Parkinson’s and even dementia! Both patients had metal-on-metal hip prostheses, and both patients’ cobalt levels were reduced after removal of the metal-on-metal prosthesis. The tragedy, however, is that patients with extreme cases of cobalt toxicity may have injuries that are too severe to be reversed. Total hip replacement is generally a successful operation, with a long clinical history of good outcomes. The DePuy knee is made from a combination of metal and plastic parts including a Cobalt-Chromium-Molybdenum alloy. Metal particles in the body are often slough off metal hip implants and are released into the individual bloodstream and soft … In an attempt to decrease wear at the interface of the articulation, metal-on-metal bearings (Box), composed of cobalt and chromium, have gained widespread popularity and have been used extensively, particularly in the United States. Cobalt, titanium and other metals in hip replacements can cause metallosis, or metal poisoning. He is shown biking around Anchorage, Alaska, where he lives and practices. DePuy used the same 510(k) submission process that so many manufacturers use. 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.”. 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. Besides the symptoms associated with other forms of metallosis, cobalt toxicity can cause patients to suffer from fever, inflammation, and low thyroid levels. As it turns out, their local brewer had started using a form of cobalt sulfate to create a better foam on top. Cobalt poisoning can also occur from the wear and tear of some cobalt/chromium metal-on-metal hip implants. (MJA 2011; 194: 649-651). DePuy’s negligence does not end there, either. However many may face a side effect know as metallosis from the hip replacement or a similar side effect called cobalt poisoning. 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. Infection can occur years after knee replacement surgery, when bacteria enter the bloodstream and infect the surgical site, according to MayoClinic.com 1. Still, executives in Johnson & Johnson’s DePuy Orthopaedics unit kept selling the A.S.R. However, not everyone loves their new knee. The direct effect of cobalt on cells has recently been explored. She had been admitted to the stroke unit and treated with ongoing clopidogrel. Provenance: Not commissioned; externally peer reviewed. This went on for a couple of years. Cobalt poisoning is an intoxication brought on by having too much cobalt in the body. When the metal is smelted, it becomes very hard. Many metal-on-metal (MoM) total hip replacement implants have been recalled due to high failure rates. Case Studies. Cobalt poisoning is a severe side effect of a metal-on-metal hip replacement can cause severe tissue damage, bone death, pain, and other severe symptoms. Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Blood levels. At revision surgery, the titanium stem was retained, and the metal head and cup were changed to ceramic and polyethylene versions, respectively. Cobalt poisoning can manifest with symptoms of varying degrees of severity and can even cause death. We are finding cobalt poisoning in too many patients with metal-on-plastic and metal-on-ceramic hips. They knew it was dangerous. That is why, if you were critically injured because of a defective cobalt hip replacement, you need an advocate like McGowan, Hood & Felder, LLC on your side. At review, she had neurological symptoms, including cognitive decline, memory difficulties and depression, which had been present for 7 months since a cerebrovascular episode. The British Hip Society recommends regular follow-up of patients with metal-on-metal hip replacements for at least 5 years and probably for the life of the prosthesis.2 Clinical manifestations of cobalt toxicity may occur many years after implantation of the prosthesis and appear to stay elevated over extended periods of time.13 Long-term exposure to cobalt may also be associated with cancer.14 Patients should therefore be followed up carefully, with specific questioning about alterations in neurological, cardiac, respiratory and endocrine function. It happens when there’s friction between metal surfaces. Hip replacement patients should be relatively pain-free three months after surgery. 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. Towers psychological symptoms were alleviated and his mental health returned to normal. Metallosis is a reputed blood poisoning condition that often develops when high levels of toxic metals are present in the blood. Cobalt; Poisoning; Literature review; Neurotoxicology;Cobalt poisoning; Beer drinkers; Cobalt cardiomyopathy A group of 48 beer drinkers developed a form of heart disease (cardiomyopathy) unique to that group. The tragedy, however, is that patients with extreme cases of cobalt toxicity may have injuries that are too severe to be reversed. Given the patient’s constellation of symptoms and lack of other significant past medical history, the differential in this case was relatively limited. Skin discoloration and joint effusion (arrow) after knee arthroplasty failure, prior to revision surgery. This was the result of a hip replacement she had undergone several years prior. The effects of the cobalt alloy hips were life-altering for Frances. Cobalt poisoning symptoms. Before his hip replacement surgery, the patient had been working full time and enjoyed excellent general health, apart from pain and stiffness in his right hip secondary to osteoarthritis. At 8-week follow-up after the revision surgery, the patient reported significant improvement in his energy levels and a decrease in muscle pains. Chromium Chromium poisoning is as dangerous as cobalt poisoning. He had a terrible time. These include metal-on-metal knee and hip joint implants. He had no hip symptoms, but an x-ray showed quite marked bone loss around the acetabular component. 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. Some of the hip replacement parts can cause cobalt to leak into the bloodstream, causing symptoms similar to toxic levels of cobalt ingestion. Since the advent of proper brewing techniques “beer-drinkers cobalt toxicity” is also a relatively rare occurrence [21-23]. Of course it will. He had significantly improved exercise tolerance and was able to walk without restriction. Hip replacement patients should be relatively pain-free three months after surgery. (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. It happens when there’s friction between metal surfaces. Blood and urine tests, x-rays and ECG (electrocardiogram, or heart tracing) may be performed. Some of the hip replacement parts can cause cobalt to leak into the bloodstream, causing symptoms similar to toxic levels of cobalt ingestion. CT angiogram, echocardiogram and thyroid function test results were all normal and she had no previous history of depression or dementia. She had particularly noted difficulty in remembering names and registering information (both written and aural), headaches and cerebellar signs (ataxia and dysdiadochokinesis). We report two Australian patients with possible cobalt toxicity related to metal-on-metal total hip replacements. To learn more about your rights and options, or to schedule a free consultation at one of our offices, please call 803-327-7800 or fill out our contact form. They knew, and they did nothing. Cobalt poisoning can also occur from the wear and tear of some cobalt/chromium metal-on-metal hip implants. Your doctor will perform a blood test to confirm whether you do indeed have metallosis. These include metal-on-metal knee and hip joint implants. 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). Randy has also been awarded the distinction of being a “Super Lawyer” 10 times in the last decade. X-rays showed a well fixed, well aligned implant, with mild osteopaenia around the acetabular component. The tragedy, however, is that patients with extreme cases of cobalt toxicity may have injuries that are too severe to be reversed. 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. Patients with elevated chromium levels often show similar symptoms as those with elevated cobalt levels. 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. Immediately before the revision surgery, the patient’s serum cobalt level was 258 nmol/L, with a normal level of chromium (88 nmol/L). But fans are asking when that hip replacement actually happened. A good, close friend had hip replacement a few years back. The friction releases tiny metal particles into your bloodstream that could trigger a hypersensitive immune response in your body. 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. The concentration of cobalt in the joint fluid was 4218 nmol/L and chromium was 217 000 nmol/L. Our defective medical device lawyers have been fighting against medical device manufacturing companies for many years. Cobalt is also component of cyanocobalamin also known as vitamin B12, which is widely consumed.

The other danger for cobalt poisoning is that it could mimic other conditions. 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. Symptoms of Metallosis. 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. 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. The ASR metal cup and head were removed and the stem retained. 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. Any of these symptoms can be signs of cobalt poisoning. On last night's 'Grey's Anatomy,' Richard Webber was diagnosed with cobalt poisoning due to a hip replacement. 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. The other danger for cobalt poisoning is that it could mimic other conditions. The devices are manufactured from blended metals that could include titanium, nickel, cobalt, chromium, and molybdenum. 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). We believe our patients’ symptoms were related to their elevated cobalt levels, resulting from cobalt leaching out of their hip prostheses.
