Hand joint replacement surgery is most commonly recommended to patients with severe arthritis facing severe pain or swelling in the hand joint. Hand joint replacement is a less common type of surgery. Joint fusion is an alternative for Hand joint replacement. For a joint fusion, the joint is removed and the bone ends are fused together so that the two bones become one solid bone. Joint fusion is very effective in managing the pain in the joint but it eliminates the motion of the fused joint. Young patients, with higher physical activity, may be recommended a joint fusion because of the stress demand on the joint. The high stress demand on the joint can be a reason of rapid wearing out of the artificial joints. However, Hand joint replacement is always a better option for those who desire an improvement in the functioning of hand. Another method employed to fight hand joint pain is surgical cleaning or salvage procedure. This method is generally used in cases of early wear and tear, and in cases of rheumatoid arthritis where there is a large amount of inflamed tissues. Surgical cleaning is helpful when the joints at the end of fingers are affected by arthritis.
The Hand and its Joints
The hand is made up of many different bones. The base of the hand has two rows of carpal bones, which, along with the radius and ulna, form the wrist joint. Other than carpal, hand has several bones in the fingers and thumb. A joint is formed whenever two or more bones meet.
Each finger has three joint:
Each finger has three joint:
Each thumb has two joints. The ends of the bones, where they meet to form a joint, are covered with a layer of articular cartilage which allow smooth movement of the bones. The joint is enclosed with a thin membrane called synovium, which secretes a fluid called synovium fluid that lubricates the joint.

Hand Joint Replacement SurgeryHand joint replacement surgery is also known as hand joint anthroplasty. This surgery is typically advised to patients suffering from acute arthritis or those having a severe fracture of the hand joint. In hand joint replacement, the painful or damaged joint is surgically replaced by an artificial joint. Implants, for most of the joint replacement, are made up of metal or plastic. However, for Hand joint replacement, a new type of joint is commonly used. This joint is made of either silicone rubber or patients own tissues such as the tendons.
The major reasons that account for hand joint replacement are osteoarthritis, rheumatoid arthritis and fractures. Osteoarthritis is an age driven arthritis that lead to wearing out of articular cartilage which in turn damages the joint bones and cause severe pain. In rheumatoid arthritis, the membrane surrounding the joint gets inflamed. The third condition that lead a patient towards hand joint replacement surgery is, a severe fracture of the hand joints.
