While many people associate joint replacements with older people, many younger people end up needing them as well. Unfortunately, this is one time when young age may actually work against someone. Many orthopedic surgeons are reluctant to do full hip replacements on patients who are under 50 years old because of their active lifestyles and life expectancy. These two factors can bring about the need to revise the hip replacement at a later date, causing another surgery. IN an effort to reduce the use of full replacements, surgeons are now doing a metal-on-metal sort of hybrid partial replacement, called resurfacing total hip arthropasty (THA). It appears to have a longer lasting outcome. This procedure doesn't involve the whole hip and is easier to remove than a full replacement, if needed. The authors, believing that resurfacing THA is better for younger, active adults, compared the findings of patients below 50 years old with those over 50 years. The 576 patients in this study had a h...
Drug eluting stents and bare metal stents are in the news these days, especially on the business pages as companies try to prove that "mine is better". I am asked on numerous occasions by patients what they should do if they have one or the other type of stent put in. The answer to this one is quite easy. Just follow the advice of your doctor about control of your medicines , nutrition and exercise , and don't spend any time at all worrying about which one of these stents is better. Let me explain. When a tight spot (blockage or stenosis) is found in a coronary artery it is similar to when a pipe is blocked in your house, flow does not go through adequately. We try to unblock the flow of blood in the coronary artery . There are several ways to do this that involve different instruments. In the early days of intervention on coronary arteries , we used balloons to open the vessel and they worked pretty well. When they worked (80% of the time) the artery often started ...
We know that exposure to the sun can damage our skin and cause skin cancer. A recent study also showed that chronic skin allergy to metals in orthopedic implants can also lead to skin cancer.
Orthopedic implants are used to replace something that are missing or damaged. Implants are used for a number of reasons, for example:
Rods, pins, screws or plates to anchor fractured bones
Not all implants contain metal, however, many do contain metal and metal alloys such as nickel, cobalt and chromium. These metals help make the implants stronger and more durable, however, some people have an allergic reaction which can appear on the skin as a rash or inflammation. This inflammation might cause joint pain, swelling or joint failure.
Researchers at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis recently published a study that looked at the effects of chronic allergic reaction from metal implan...
