What Is Kienbock’s Disease?

Kienbock’s disease is a condition that affects the lunate bone, one of the small bones in the wrist. It occurs when the blood supply to the lunate bone is disrupted, causing the bone to die (avascular necrosis).

Kienbock’s disease is rare, and it typically affects men between the ages of 20 and 40. The exact cause of Kienbock’s disease is unknown, but it is thought to be caused by a combination of factors, including:

* Trauma: A sudden injury to the wrist, such as a fall or a blow to the hand, can damage the blood vessels that supply the lunate bone.

* Repetitive motion: Repetitive motions of the wrist, such as those involved in certain sports or jobs, can also damage the blood vessels that supply the lunate bone.

* Other medical conditions: Certain medical conditions, such as diabetes and sickle cell anemia, can increase the risk of developing Kienbock’s disease.

Symptoms of Kienbock’s disease can include:

* Pain in the wrist

* Swelling in the wrist

* Stiffness in the wrist

* Weakness in the grip

* Difficulty moving the wrist

Kienbock’s disease is diagnosed based on the patient’s symptoms and a physical examination of the wrist. Imaging tests, such as X-rays and MRI scans, may also be used to confirm the diagnosis.

Treatment for Kienbock’s disease depends on the stage of the disease. In the early stages, treatment may involve:

* Resting the wrist

* Wearing a splint or cast

* Taking pain medication

* Physical therapy

In more advanced stages of the disease, surgery may be necessary to remove the damaged lunate bone or to fuse the wrist bones together.

Kienbock’s disease can be a disabling condition, but it can be managed with proper treatment. Early diagnosis and treatment can help to prevent the disease from progressing and causing permanent damage to the wrist.
