The bone is living tissue that requires a regular supply of blood to nourish. If the blood supply to a bone stops, the bone can die. This is called osteonecrosis. The damage to the lunatic causes a painful and rigid wrist and, over time, can lead to arthritis. Because the cause of Kienböck's disease is not known. Many people with Kienböck's disease think they have a sprained wrist at first. They may have experienced some form of wrist trauma, like a fall. This type of trauma can interrupt blood flow to the lunatic. Some things may put you at greater risk for the disease. For example, most people have two glasses that supply blood to the lunatic, but in some people there is only one source. This can delay blood flow to the bone. Also, if the two bones of the forearm (the radio and ulna) are different lengths, you can press extra to the lunatic during some wrist movements. Over time, this extra stress on the bone can lead to Kienböck disease. SymptomsThe most common symptoms of Kienböck's disease include: Medical Exam Kienböck's disease is a condition that progresses slowly, and many people don't decide to see a doctor until they have experienced symptoms for several months, perhaps more. During your first appointment, your doctor will discuss your symptoms and medical history, and then examine your hand and wrist. In its early stages, Kienböck disease may be difficult for your doctor to diagnose because the symptoms are so similar to those of a sprained wrist. Imaging tests, such as X-rays and MRI images, are used to confirm a diagnosis of Kienböck disease. Kienböck disease progresses through four stages of gravity. If you are diagnosed with Kienböck disease, your doctor will plan your treatment based on several factors, which is more important, the stage of your progression. Stage 1During the first stage of the disease, the symptoms are similar to those of a wrist sprain. Although the blood supply to the lunatic has been interrupted, X-rays may appear normal or suggest a possible fracture. An MRI analysis can better detect blood flow and is useful for making diagnosis at this early stage. Stage 2The lunar bone begins to harden due to lack of blood supply during Stage 2. This hardening process is called sclerosis. In addition, the lunatic will appear brighter or whiter in X-ray areas, indicating that the bone is dying. To better assess the condition of the lunatic, your doctor may also order MRI scanners or CT scans. The most common symptoms during this stage are wrist pain, inflammation and sensitivity. Stage 3In the third stage, the dead lunar bone begins to collapse and break into pieces. As the bone begins to break, the surrounding bones can begin to change the position. During this stage, patients often experience growing pain, weakness in grip and limited wrist movement. Stage 4If the condition progresses to Stage 4, the surfaces of the bones surrounding the lunatic also deteriorate, and the wrist can become arthritic. Treatment Although there is no complete cure for Kienböck disease, there are several non-surgical and surgical options to treat it. Treatment goals are to relieve pressure on the lunatic and try to restore blood flow inside the bone. Related Articles Wrist Arthritis Wrist Sprains Non-surgical Treatment In the very early stage of the disease, pain and inflammation can be given with anti-inflammatory drugs, such as aspirin or ibuprofen. Doll immobilization for a period of time can help relieve pressure on the lunatic, and your doctor may recommend spine or casting for 2 to 3 weeks. It is important to monitor any changes in your symptoms during the early stage of Kienböck disease. If the pain is not relieved with simple treatments or returns, the doctor may recommend surgery. Surgical Treatment There are several surgical options to treat Kienböck disease. The choice of the procedure will depend on several factors, in particular to what extent the disease has progressed. Additional factors to consider are the patient's level of activity, personal objectives and the surgeon's experience with the procedures. Revascularization. In some cases, it may be possible to return the blood supply to the lunar bone. This procedure is called revascularization. It is more successful during the early stages of the disease—stages 1 and 2—before the lunatic has deteriorated significantly. Revascularization involves the removal of a portion of bone with attached blood vessels from another bone — most of the time a bone from the forearm (radius) or an adjacent bone in the hand. This piece of bone with its blood supply is called vascularized graft. It is inserted into the lunar bone. To help the bones remain in place during healing, an external fixer can be temporarily applied. This is a metallic device attached to the outside of the wrist with nails inserted into the bones. It can relieve pressure on the lunatic while the graft is healing and restoring a blood supply. Joint leveling. If the two bones of the lower arm are not of the same length, a joint leveling procedure may be recommended. Bones can be made longer using bone grafts or shortened by removing a section of the bone. This leveling procedure reduces the forces that compress the lunatic and often stops the progression of the disease. Approximate line spectomy. If the lunatic collapses severely or breaks into pieces, it can be eliminated. In this procedure, the two bones on each side of the lunatic are also eliminated. This procedure, called proximal row carpectomy, will relieve pain while maintaining partial wrist movement. (Left) The three wrist bones that are removed in a proximal row carpectomy are shaded here. (Right) An X-ray image of a wrist after a proximal row carpectomy. Fusion. To relieve pressure on the lunatic, the nearby bones of the wrist can be merged together to make a solid bone. A fusion can be partial, in which only some of the bones are merged. This procedure relieves pain and retains some wrist movement. If the disease has progressed to severe wrist arthritis, fusing all wrist bones to the radio will relieve pain and improve the hand function. Although the whole wrist movement is eliminated in a complete fusion, the rotation of the forearm is preserved. In a fusion, the bones of the wrist are held along with a plate, screws and pins. ResultsThe disease of Kienböck varies considerably in its severity, as well as its rate of progression. Each patient's response to treatment depends on the degree of damage to the bones of the lunar and surrounding wrist. Some patients may require more than one procedure if the disease continues to progress. In short, patients with Kienböck disease should not expect to return to normal wrist function after any treatment. However, treatment provides the greatest opportunity for long-term preservation of function and pain relief.
