When a joint is fused, bone or graft is fused together to make a strong bond. As a result, the joint can no longer bend and move as it did before. This may greatly reduce the amount of pain that someone experiences, but it also makes movements more awkward. Unfortunately, right now, when a fusion is done, it is permanent and range of motion as it was before the pain and the surgery will not return.

The wrist joint is a complicated one. Some of your joints are called ball and socket joints because, like with the hip, the ball of the hip fits into the socket, and allows you to swing your leg. Other joints are hinge joints, like the elbow, where you can move your joint up and down as it would with a hinge.

Osteonecrosis of the wrist, or death of bone cells in the wrist, isn't a very common problem, but it does happen. In some situations, it's easy to identify why it happened. For example, it can happen after someone breaks their wrist and the blood supply to the bone is cut off. However, many times there is no rhyme or reason as to why someone develops it.

Without knowing the specifics of your father's case, we can only give general information about what may have happened. Bone death in the wrist, called avascuar necrosis is caused by lack of blood flow to the specific bone. This could be caused by a trauma, like a fracture, which interferes with the blood flow and doesn't allow the nutrients from the blood to reach the bones. But most often, doctors don't know what causes it.

Avascular necrosis or osteonecrosis (bone death) of the carpal bones (wrist) causes pain, limited motion of the wrist, and weakness. Frequently, patients with this problem end up with arthritis in the affected wrist. The author of this article examined different treatment methods of avascular necrosis.

Triangular fibrocartilage complex is a disorder of the wrist. The cartilage, tough fibrous connective tissue, is damaged or torn. The most common sign of triangular fibrocartilage complex is pain on the ulnar side of the wrist, the outside of the arm, closest to the "little" finger.

Kienbock's disease is a condition in which the lunate loses its blood supply and dies, causing pain and stiffness with wrist motion. In the late stages of the disease, the bone collapses, shifting the position of other bones in the wrist. This shifting eventually leads to degenerative changes and osteoarthritis in the joint.

The wrist is made of eight separate small bones, called the carpal bones. There are two rows of carpal bones that connect the two bones of the forearm, the radius and the ulna, to the bones of the hand.

Carpal tunnel syndrome (CTS) is often accompanied by numbness and tingling of the fingers affected by the compressed or pinched median nerve. When there is no numbness, there can still be pain and loss of strength contributing to the problem.

Results of studies around surgical outcomes for Kienböck's disease are not consistent. What works best? When should the affected wrist bone (the lunate) be surgically removed? Can surgeons use the amount of damage to the joint surfaces as a guide in making this decision?
