Arthritis of The Hip
What is Arthritis of the Hip?
Arthritis of the hip is a disease which wears away the cartilage between the femoral head, or hip ball, and the acetabulum, or hip socket, causing the two bones to scrape against each other, raw bone on raw bone. When this happens, the joint becomes pitted, eroded and uneven. The result is pain, stiffness and instability, and in some cases, motion of the leg may be greatly restricted.
Osteoarthritis, which is the most common form of arthritis in the United States, is degenerative and, although it most often occurs in patients over the age of 50, it can occur at any age, especially if the joint is in some way damaged.
It is usually confined to the large weight-bearing joints of the lower extremities, including the hips and knees, but may affect the spine and upper extremity joints, too. Patients with osteoarthritis often develop large bone spurs, or osteophytes, around the joint, further limiting motion.
Unlike osteoarthritis, which is a "wear and tear" phenomenon, rheumatoid arthritis is a chronic inflammatory disease that results in joint pain, stiffness and swelling. The disease process leads to severe, and at times rapid, deterioration of multiple joints, resulting in severe pain and loss of function.
