Common causes of arthritis, which usually affects the hand and wrist, include mechanical factors including joint stability, biochemical factors in the cartilage and other risk factors, such as overuse, joint infections, traumatic injuries and age, according to the Cleveland Clinic. Hereditary factors possibly contribute to the development of rheumatoid arthritis.
A temporary or persistent inflammation in a joint and nearby soft tissues typically leads to arthritis, states Cleveland Clinic. In some cases, joint trauma such as a broken finger causes arthritis. The stability and alignment of joints are possible factors that lead to arthritis, as they influence the dispersal of forces across a joint, thereby affecting its lifespan. Individuals who inherited the disease often experience arthritis at an early age.
Osteoarthritis typically occurs in the hands and weight-carrying joints, such as the knees and hips, says the Cleveland Clinic. People with osteoarthritis experience a painful and deformed joint and restricted joint movement. Rheumatoid arthritis is a common inflammatory condition that affects the whole body, particularly the joints, and it starts in the hands, wrists and feet.
Osteoarthritis commonly affects older people and women, particularly those who are 20 to 40 years old, notes the Cleveland Clinic. Symptoms include intermittent joint pain, reduced range of motion as the disease progresses, and swollen joints that turn red or tender when touched.
