Stiffness in fingers may occur when there are problems within and around the structures of a joint, including in ligaments and muscles, explains the American Society for Surgery of the Hand. Some of these problems include arthritis, fractures, dislocations, sprains, and tendon and muscle injuries.
Joint stiffness is the sensation of difficulty moving a joint or the apparent loss of range of motion of a joint. It often accompanies joint pain and swelling. Common causes of joint stiffness include injury or disease of the joint, with the most important cause being arthritis, according to WebMD. Joint stiffness that occurs in the morning and lasts longer than an hour is a good reason to suspect arthritis.
Arthritis is the loss of cartilage that covers the ends of the bones and allows for smooth motion at the joints. It can have a multitude of causes, including genetics, wear and tear, and injuries such as fractures. Typically, symptoms of rheumatoid arthritis include painful swelling, inflammation and stiffness in the fingers, notes WebMD.
Joint damage, including stiffness, can occur due to injury to the joint, reports the American Society for Surgery of the Hand. Sometimes, injuries or inflammation of the adjacent areas can cause pain that may limit the movement of a joint and appear to be joint stiffness.
