3D medical animation still showing Arthritis infected<unk> . Arthritis of the<unk>  is common in females. Osteoarthritis of the<unk>  joints is much less common than rheumatoid arthritis. As the arthritis progresses, the finger gets deformed and lose its functions. Moreover, many patients with rheumatoid arthritis have this dysfunction present in both<unk> s and become disabled due to chronic pain. Osteoarthritis is most common at the base of thumb and is usually treated with pain pills, splinting or steroid injections. Carpal tunnel syndrome is a common disorder of the<unk> . This disorder results from compression of an important nerve in the wrist. Disorders like diabetes mellitus, thyroid or rheumatoid arthritis can narrow the tunnel and cause impingement of the nerve. Carpal tunnel syndrome also occurs in people who overuse their<unk>  or perform repetitive actions like using a computer key board, a cashiers machine or a musical instrument. When the nerve is compressed, it can result in disabling symptoms like numbness, tingling, or pain in the middle three fingers. As the condition progresses, it can lead to muscle weakness and inability to hold objects. The pain frequently occurs at night and can even radiate to the shoulder. Even though the diagnosis is straightforward, the treatment is not satisfactory. Dupuytren's contracture is another disorder of the fingers that is due to thickening of the underlying skin tissues of the palm. The disorder results in a deformed finger which appears thin and has small bumps on the surface. Dupuytren's contracture does run in families, but is also associated with diabetes, smoking, seizure recurrence and other vascular disorders. Dupuytren's does not need any treatment as the condition can resolve on its own. However, if finger function is compromised, then surgery may be required. Ganglion cysts are soft globular structures that occur on the back of the<unk>  usually near the junction of the wrist joint. These small swellings are usually painless when small but can affect<unk>  motion when they become large. The cysts contain a jelly like substance and usually do disappear on their own. If the ganglion cyst is not bothersome, it should be left alone. Just removing the fluid from the cyst is not curative because fluid will come back in less than a week. Surgery is often done for large cysts but the results are poor. Recurrences are common, and there is always the possibility of nerve or joint damage. Inflamed tendons of the<unk> . Tendinitis is disorder when tendons of the<unk> s become inflamed. Tendons are thick fibrous cords that attach small muscles of the<unk>  to bones. A Tendon is useful for generation of power to bend or extend the finger. When repetitive action is performed, tendons often get inflamed and present with pain and difficulty for moving the finger. In most cases, tendinitis can be treated with rest, ice and wearing splints. In some cases, an injection of corticosteroid may help. Tendinitis is primarily a disorder from overuse but if not treated properly, can become chronic. Trigger finger is a common disorder which occurs when the sheath through which tendons pass, become swollen or irritated. Initially, the finger may catch during movement but symptoms like pain, swelling and a snap may occur with time. The finger often gets locked in one position and it may be difficult to straighten or bend the finger. Trigger finger has been found to be associated with diabetes, gout and rheumatoid arthritis.
