Titanium cobalt is used as frequently as cobalt-chromium alloys in joint replacement components. Titanium alloys are biocompatible, will not corrode, nor change inside the body. Titanium cobalt is more elastic and favorable to the natural bone surrounding the implant.
Can knee replacements cause cobalt poisoning?
10 Million People with Hip, Knee and Shoulder Replacements Are at Risk of Being Poisoned by Cobalt.
Is cobalt used in joint replacement?
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. These devices are made from a blend of several metals, including chromium, cobalt, nickel, titanium and molybdenum.
What metals are used in knee replacement?
The metals used in artificial knees are alloys of cobalt-chromium and titanium. The bearing portion of the joint is made of a high-grade, wear-resistant plastic. The metal-plastic bearing combination is the most common type used in knee replacement implants worldwide.
Can you reverse cobalt poisoning?
The symptoms and problems associated with long-term cobalt poisoning are rarely reversible. People who have such poisoning will likely have to take medicine for the rest of their life to control the symptoms.
What happens when you breathe in cobalt?
Exposure to high levels of cobalt in the air may result in health problems. Workers breathing air containing 100,000 times the concentration of cobalt normally found in ambient air experienced severe lung effects such as wheezing, asthma, and pneumonia.
How common is cobalt poisoning?
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.
What does cobalt do to your body?
Cobalt is toxic to the heart muscle. It can cause heart muscle disease (toxic cardiomyopathy) after too much exposure. An increase in red blood cells (polycythemia) may be a symptom of too much cobalt. Not treating this issue can cause congestive heart failure.
What are the side effects of cobalt?
It might cause heart problems, hearing loss, or vision loss in some people. When inhaled: Cobalt is POSSIBLY UNSAFE when inhaled. Cobalt might cause heart problems, lung disease, hearing loss, and vision loss in people who are exposed to cobalt dust in certain industries.
How long does titanium last in the body?
Benefits of Medical Titanium
Titanium is also incredibly durable and long-lasting. When titanium cages, rods, plates and pins are inserted into the body, they can last for upwards of 20 years. And dental titanium, such as titanium posts and implants, can last even longer.
How long do titanium knee replacements last?
In 85% to 90% of people who have a total knee replacement, the knee implants used will last about 15 to 20 years. This means that some patients who have a knee replacement at a younger age may eventually need a second operation to clean the bone surfaces and refixate the implants.
Will a knee replacement set off a metal detector?
Metal implants in the body, including joint replacements, plates, screws, and rods, can set off metal detectors during airport security screenings.
What is the most commonly reported problem after knee replacement surgery?
Knee replacement surgery can result in physical complications ranging from pain and swelling to implant rejection, infection and bone fractures. Pain may be the most common complication following knee replacement.
