Most people would be surprised to know that total hip replacements (THRs) have been around since the 1930s. Today's successful use of THRs reflects the many implant changes in design and materials that have taken place since those early attempts. In this article, orthopedic surgeons from the New York University Hospital for Joint Diseases review the history of THRs up to and including today's surface replacement arthroplasty (SRA). SRA is a type of hip replacement that replaces the arthritic surface of the joint. But it removes far less bone than the traditional total hip replacement. Because the hip resurfacing removes less bone, it may be preferable for younger patients who are expected to need a revision (second) hip replacement surgery as they get older and wear out the original implant. The surface replacement arthroplasty (SRA) is done by dislocating the femoral head out of the socket. Special powered instruments are used to shape the bone of the femoral head so that the new meta...
Ask someone with rheumatoid arthritis to tell you about their biggest frustration and chances are they'll mention the misconception that RA is like osteoarthritis (OA). To help you educate those around you, HealthCentral's RA community will be featuring a trio of posts with information and stories that can help others understand. We'd like to thank Tiffany Westrich, the CEO and cofounder of the International Autoimmune Arthritis Movement, who will be working with us on this project. Today, she's writing about what it's like to live with RA .
Rheumatoid arthritis is an autoimmune disease. In autoimmune diseases, the immune system mistakenly attacks healthy tissue. In cases of RA, this causes inflammation in joints and tendons. RA is a chronic illness, there is no cure. We do not know what causes RA, but gingivitis, smoking and a particular bacteria in the gut are implicated in triggering the immune response that leads to the development of the disease.
Osteaoarthritis is a...
