Some possible causes of wrist-joint pain include injuries and arthritis, according to Mayo Clinic. Other diseases and conditions, such as carpal tunnel syndrome, ganglion cysts and Kienbock's disease also cause wrist-joint pain.
A wrist joint is composed of two rows of eight small bones located between the forearm bones and bones in the hand, explains Mayo Clinic. The wrist bones are connected to each other by bands of ligament. The ligaments also connect the wrist bones to the forearm bones and hand bones. Pain in the wrist joint results when the joint gets damaged. The pain may also hinder the ability of the hand to work.
A wrist-joint injury occurs, for instance, when an individual falls forward on his outstretched hand, notes Mayo Clinic. This creates a sudden impact in the joint, potentially causing joint sprains, fractures and strains. Repetitive activities such as hitting a tennis ball are also injurious to the wrist joint. When continuously undertaken without a break, these activities can cause tissue inflammation or stress fractures in the wrist joint. For instance, De Quervain's disease is one stress injury that results in pain at the thumb base.
Osteoarthritis and rheumatoid arthritis are arthritis types that cause wrist-joint pain, states Mayo Clinic. While the former is a result of deterioration of the cartilage that protects the bone ends, the latter occurs when the body's immune system attacks the tissues, mostly in the wrist.
