What is Kienböck’s Disease?

The lunate is one of the eight small carpal (wrist) bones. When blood supply to it is limited, a condition known as Kienböck’s disease develops. The cause of the disease is unknown. Because a lack of blood to the bone can cause bone deterioration, the disease may present with any of the following symptoms:
  • Wrist pain
  • Wrist swelling
  • Wrist stiffness
  • Decreased grip strength
  • Tenderness
  • Difficulty turning the palm up
When the disease is left untreated, symptom severity increases as the disease progresses through its five stages.

How is Kienböck’s Disease Treated?

There is no cure for Kienböck’s disease. However, when the disease is detected and treated early, immobilization and anti-inflammatory medications can be used to decrease or eliminate symptoms. When the disease reaches its final stages or produces severe symptoms, surgical intervention may be required. This is something best discussed with an orthopedic hand surgeon.
