Is carpal tunnel syndrome the same as other problems like Kienbock's disease?
Carpal tunnel syndrome and Kienbock's disease are two different disorders. Carpal tunnel syndrome is a repetitive stress disorder that causes irritation of the nerves that go from the forearm into the hand. Kienbock's disease is a disease of a bone in the wrist called the lunate. With Kienbock's disease, blood doesn't reach the bone to provide it with nutrients and the bone cells begin to die.
Doctors do wonder if there is some role to repetitive motions with Kienbock's disease, but nothing has been proven yet.
