This may require stabilization with pins or screws. Repetitive stress is another condition that affects the wrist. It can be caused by typing, sports, or other activities that involve repetitive motions. Repetitive stress can cause the carpal tunnel to become thickened and inflamed. The carpal tunnel is a tube of nerves and tendons that passes through the wrist. Tendinitis, sprains, and strain are other common injuries, which affect the connective tissues of the wrist. Wrist pain may also result from medical conditions, such as osteoporosis. This condition decreases bone density and increases the risk of fracture. The wrist can also be affected by arthritis, including osteoarthritis, rheumatoid arthritis, and gout. These conditions involve swelling of the joints from various causes. Arthritis can worsen with age.
