What is joint replacement surgery? Joint replacement surgery removes damaged or diseased parts of a joint and replaces them with new, man-made parts. Replacing a joint can reduce pain and help you move and feel better. Hips and knees are replaced most often. Other joints that can be replaced include the shoulders, fingers, ankles, and elbows.
What is osteogenesis imperfecta? Osteogenesis imperfecta (OI) is a disease that causes your bones to break (fracture) easily. OI is also called brittle bone disease. Your symptoms may be mild or severe, depending on the type of OI you have.
What is psoriasis? Psoriasis is a chronic (long-lasting) disease in which the immune system works too much, causing patches of skin to become scaly and inflamed. Most often, psoriasis affects the: Scalp. Elbows. Knees. The symptoms of psoriasis can sometimes go through cycles, flaring for a few weeks or months followed by times when they subside (or go into remission). If you have psoriasis, you may have a higher risk of getting other serious conditions, including: Psoriatic arthritis. Heart attack or stroke. Mental health problems, such as low self-esteem, anxiety, and depression.
What is tendinitis? Tendinitis is swelling and pain in a tendon, which is tissue that connects muscles to bones. It is a common condition, usually caused by repeated injuries to a tendon.
What is fibrous dysplasia? Fibrous dysplasia happens when abnormal fibrous (scar-like) tissue replaces healthy bone. The fibrous tissue weakens the bone over time, which can lead to: Broken bones. Bones that are misshapen (bowed or crooked). The disease can affect any bone in the body. Some people have no symptoms or only a few symptoms. Other people may have more symptoms. Although there is no cure for fibrous dysplasia, treatments may help to lessen pain, and physical therapy may help strengthen muscle and improve movement.
What is bursitis? Bursitis is a common condition that causes swelling and pain around muscles and bones. Bursitis is the swelling of the bursa, a small, fluid-filled sac that acts as a cushion between a bone and other moving parts, such as muscles, tendons, or skin.
A bioengineered molecule designed to bind together key components found in the fluid that surrounds joint areas may improve lubrication and minimize friction. This could potentially slow the degeneration of cartilage tissue that occurs in knee osteoarthritis, according to a study conducted in rats and funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases. The study was published in Nature Materials. The synovial fluid that bathes our joints is composed of several types of lubricants, including hyaluronic acid (HA) and lubricin. In healthy joints, this fluid ensures that tissues move together smoothly and without
Using magnetic resonance imaging (MRI), a team of scientists has detected structural changes in the knee joint that precede signs of osteoarthritis seen on X-rays. The study, which was supported in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), calls into question the assumption that damage to cartilage is the primary underlying cause of osteoarthritis. The findings appeared in the journal Arthritis and Rheumatology.
Psoriasis is a chronic skin condition characterized by itchy red patches and silvery scales, usually on the elbows, knees or scalp. It affects about 2 percent of Americans, and is sometimes associated with other health problems, such as arthritis, diabetes and heart disease. The causes are not fully understood, but the condition is related to an abnormal immune assault on skin cells that triggers inflammation. Scientists have been trying to understand the molecular details of what causes psoriasis. Now, two studies funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and published in
¿Qué es la osteogénesis imperfecta? La osteogénesis imperfecta es una enfermedad que hace que los huesos se rompan (se fracturen) fácilmente. También se le conoce como la enfermedad de los huesos de cristal. Sus síntomas pueden ser leves o graves, dependiendo del tipo de osteogénesis imperfecta que tenga.
