![]() ![]() Revascularization involves restoring or increasing the blood supply to the lunate bone. ![]() The options depend on several factors, including the stage of disease, the person’s activity level, and their personal goals. ![]() Several different surgical procedures are available for patients with Kienböck’s disease. If over-the-counter (OTC) anti-inflammatory medications start to become less effective, the doctor may recommend surgery.Ī physical therapist can teach the patient how to use the wrist in a way that is less painful and slows down the progression of the disease. Cortisone injections: These may help with symptoms.Anti-inflammatory drugs: Ibuprofen, aspirin, and other painkillers may help manage swelling and pain during the early stages.Resting the wrist increases the chance of restoring blood flow to the lunate bone. Resting the wrist: During the early stages, it might be possible to splint and cast the wrist for several months.The following non-surgical options can help: Share on Pinterest A physical therapist can advise on less painful ways to use the wrist. There is no evidence to confirm that certain jobs increase the risk of developing Kienböck’s disease. One study found that 9.4 percent of patients with cerebral palsy also had Kienböck’s disease. This extra stress could lead to Kienböck’s disease.ĭiseases that may increase the risk include lupus, cerebral palsy, sickle cell anemia, and gout. If the ulna and radial bones are different lengths, this may put extra pressure on the lunate in certain wrist motions. There may be skeletal variations, for example, an abnormally shaped lunate bone.Īnother cause could be that the ulna, the long bone in the forearm, is shorter than normal.Trauma may affect blood supply, for example, a single blow to the wrist.Blood does not drain away properly through the veins.Most people have two blood vessels supplying blood to the lunate bone, but some have just one. Share on Pinterest In Kienböck’s disease, a disrupted blood supply causes the lunate bone to collapse. Stage 4: The lunate has completely collapsed, and nearby bones have also become damaged and arthritic. Stage 3: The bone starts to fragment and collapse. When bone loses its blood supply, it hardens. ![]() Stage 2: X-rays show that the bone is unusually dense. There may be pain, swelling, and a risk of fracture. The bone appears normal in an x-ray but may show changes on an MRI. Stage 1: The lunate loses its blood supply. In time, the mechanics of the wrist become affected, leading to abnormal stress and wear inside the wrist. The progression of Kienböck’s disease varies between patients, but it tends to develop slowly and subtly over a number of years. In the early stages, the patient might experience pain and swelling, similar to a wrist sprain, but, unlike a sprain, the symptoms will persist and get worse. Damage to this bone can lead to stiffness and pain and eventually arthritis of the wrist. The lunate bone is crucial for proper movement and support of the joint. These are the bones that make flexible positioning of the hand possible. The carpal bones consist of eight wrist bones that connect the hand to the forearm.
