![]() The reduced blood supply might be the result of a previous injury to the blood vessels. A bone with a limited blood supply may be more at risk of developing the disease after an injury. ![]() Some bones in the body simply have fewer blood vessels that bring in blood. The way that blood vessels supply the lunate is thought to play a role in Kienbock's disease. But the injury alone does not seem to cause the disease. The injury may be a single incident, such as a sprain, or a repetitive trauma. Usually the patient has injured the wrist. Related Document: A Patient's Guide to Wrist Anatomy CausesÄoctors have not determined exactly what causes Kienbock's disease. The metacarpals attach to the phalanges, which are the bones in the fingers and thumb. The metacarpal bones are the long bones that lie underneath the palm. The carpal bones connect the two bones of the forearm, the radius and the ulna, to the bones of the hand. It is the bone that is affected in patients with Kienbock's disease. The wrist is made of eight separate small bones, called the carpal bones. At the same time, the wrist must provide the strength for heavy gripping. The wrist must be extremely mobile to give our hands a full range of motion. These joints and bones let us use our hands in lots of different ways. The wrist is actually a collection of many joints and bones. The anatomy of the wrist joint is extremely complex, probably the most complex of all the joints in the body. While the exact cause of this uncommon disease isn't known, a number of treatment options are available. This shifting eventually leads to degenerative changes and osteoarthritis in the joint. In the late stages of the disease, the bone collapses, shifting the position of other bones in the wrist. In order to properly spell and pronounce medical terms, it is helpful to learn the suffixes.Kienbock's disease is a condition in which one of the small bones of the wrist loses its blood supply and dies, causing pain and stiffness with wrist motion. However, when transcribing or reading medical reports the suffix is always clearly written. It is common that suffixes will not be explicitly stated when defining a medical term in the workplace. Suffixes are not always explicitly stated in the definition of a word. Suffixes in medical terms are common to English language suffixes. It is important to spell and pronounce suffixes correctly. Suffixes can alter the meaning of medical terms. Suffixes are word parts that are located at the end of words.
