Other health effects associated with exposure to high levels of cobalt through ingestion may include: nausea and vomiting, vision problems, dermatitis, thyroid damage, severe damage to the heart, and even death.

Cobalt is an essential raw material for superalloy, cemented carbide, diamond tool, batteries, anticorrosive and magnetic materials. It is widely applied in fields including aerospace, electronic appliances, machinery manufacturing, automobiles, chemical industry, agriculture, ceramics, etc.

Explain Why can’t you use density or reactivity to determine whether a sample is cobalt or nickel? The density of iron is much less than cobalt or nickel, and it reacts with oxygen in the air. We can also use properties to tell nickel and cobalt apart.

What Are the Uses of Cobalt?

• Alloys in Industry. Alloys, or mixtures of metals, make up half the cobalt used each year.
• Electroplating.
• Alternative Energy.
• Orthopedic Implants.
• Radiation Therapy and Sterilization.
• Nutrition.
• Art Material.

Cobalt is used in alloys for aircraft engine parts and in alloys with corrosion/wear resistant uses. Cobalt is widely used in batteries and in electroplating. Cobalt salts are used to impart blue and green colors in glass and ceramics. Radioactive 60Co is used in the treatment of cancer.

One method of treating ASR Hip Replacement patients with high levels of chromium and cobalt in their blood is chelation therapy. The process involves the administration of chelating agents—the most common of which is ethylenediaminetetraacetic acid (EDTA)—to remove the poisonous metals from the body.

The red blood cells which carry cobalt are thought to have a lifespan of ninety days, so in theory when the cobalt source is removed from the body the cobalt levels should return to normal. If the cobalt has caused the body’s inflammatory process to kick it, more serious ailments may have begun.

Cobalt Chromium Metal Poisoning from Hip Replacements The friction releases tiny metal particles into your bloodstream that could trigger a hypersensitive immune response in your body. Your doctor will probably order blood tests to check the levels of metal in your bloodstream.

Local symptoms of metallosis include hip or groin pain, numbness, swelling, weakness and a change in the ability to walk, according to the U.S. Food and Drug Administration. You may notice problems with your skin, heart, kidneys, nervous system or thyroid before you experience local symptoms.

Metallosis can have serious effects, such as the death of bone or tissue, lead to implant failure, and cause severe debilitating pain. It can lead to the patient losing cognitive functioning, tissue damage and loss, and serious damage to the patient’s nervous system.

When they do occur, titanium allergy symptoms can range from mild to severe and can include:

• loosening of the implants (or implant failure)
• rash or hives.
• sores and swelling in the soft tissues of the mouth.
• chronic inflammation in the gums around the implant.
• problems with wound healing.
• chronic fatigue syndrome.

Sadly, in extreme cases, hip replacements can kill you. A defective hip implant system that causes metallosis, a condition destroys ligaments, muscle, tendons – and can affect the heart and brain.

Unfortunately, when the tiny ions arrive at the liver and kidneys, an oxidative reaction can occur, leaving these important organs unable to purify the blood as they are meant to do. Chromium poisoning can lead to Stryker hip kidney problems and Stryker hip renal failure, causing impairment of normal kidney functions.

7 out of 9 patients showed short-term memory loss and possible dementia. The authors found a high incidence of cognitive disability and depression among patients who suffered from implant-caused metal poisoning (metallosis).

Cobalt poisoning from hip prosthesis is rare but debilitating. It’s caused when the metal wears and introduces cobalt into the bloodstream. This is a known risk with metal-on-metal implants, but newer data are showing that it is also a risk with metal-on-polyethylene implants.

Nowadays hip joint prostheses are made with metals, ceramics and plastic materials. Most used are titanium alloys, stainless steel, special high-strength alloys, alumina, zirconia, zirconia toughened alumina (ZTA), and UHMWPE.

DELAYING TOO LONG When patients are healthy, other than in their joint, they often do much better recovering from surgery. The greatest risk of delaying too long is allowing problems, such as osteoarthritis, to continue wearing down the already ragged joint.

How long does a ceramic hip last? On average, hip replacements last 20 to 25 years before repair or replacement. In one study , only 4.4 percent of people who received a hip replacement required revision surgery in the first 10 years after surgery. About 15 percent required revision by the 20-year mark.

The third generation of ceramic alumina is currently in use [4, 5], and the risk of fracture is now extremely rare [6]. In addition, wear seems to be undetectable.

The hip is really a much simpler joint. The knee has to balance off-center loads and move side to side. And with a total knee replacement, you are removing a lot of tissue and bone. Postoperative pain is higher with knees since the soft tissue affected by the surgery must stretch more than soft tissue around the hip.

70 years and 209 days

The posterior approach to total hip replacement is the most commonly used method and allows the surgeon excellent visibility of the joint, more precise placement of implants and is minimally invasive.

Studies show that more than 80% of all hip replacements across the industry last at least 15 years, and more than 70% last at least 20 years. Individual results may vary. Your results will depend on your personal circumstances.
