1 At the ends of each of our chromosomes are sections of DNA called telomeres. 2  Telomeres protect the ends of the chromosomes during DNA replication by forming a cap, much like the plastic tip on a shoelace.
Osteoarthritis (OA) is the most common type of finger arthritis. OA is also called degenerative joint disease because it is caused by wear and tear on your joints as you age. In OA, the protective tissues in your joints deteriorate with time allowing bare bone to rub on bone. This cause joint pain and swelling.
The most common forms are osteoarthritis (degenerative joint disease) and rheumatoid arthritis. Osteoarthritis usually occurs with age and affects the fingers, knees, and hips. Rheumatoid arthritis is an autoimmune disorder that often affects the hands and feet. Other types include gout, lupus, fibromyalgia, and septic arthritis. They are all types of rheumatic disease.
