Hand injury  The hand is a very complex organ with multiple joints, different types of ligament, tendons and nerves. Hand disease injuries are common in society and can result from excessive use, degenerative disorders or trauma. Trauma to the finger or the hand is quite common in society. In some particular cases, the entire finger may be subject to amputation. The majority of traumatic injuries are work-related. Today, skilled hand surgeons can sometimes reattach the finger or thumb using microsurgery. Sometimes, traumatic injuries may result in loss of skin, and plastic surgeons may place skin and muscle grafts. Arthritis of the hand is common in females. Osteoarthritis of the hand 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 hands 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 hand. 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 hand 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 hand usually near the junction of the wrist joint.
