How do I know if I have Kienbock Disease?

Kienböck disease is a rare condition characterized by the progressive collapse of the lunate bone in the wrist due to a loss of blood supply, known as avascular necrosis. You may suspect Kienböck disease if you experience persistent, localized wrist pain, stiffness, and decreased grip strength that does not resolve with typical rest or over-the-counter anti-inflammatory medication.

What are the early signs of Kienböck disease?

Kienböck disease typically presents with chronic, dull, aching pain centered over the middle of the wrist, directly behind the palm. Unlike a common sprain, the pain associated with Kienböck disease often persists for months and may be accompanied by swelling and a noticeable decrease in your range of motion. Many of the 186 members in our DiseaseMaps community report that their symptoms began gradually, often exacerbated by repetitive wrist use or heavy lifting.

How can I self-assess for Kienböck disease?

While only a physician can provide a formal diagnosis, you can monitor your symptoms for these common patterns:

• Localized tenderness: Pain felt specifically when pressing on the lunate bone (the center of the wrist just below the palm).


• Grip weakness: A significant, measurable difference in grip strength compared to your unaffected hand.


• Persistent stiffness: Difficulty rotating the wrist or bending it backward (extension) that remains after several weeks of rest.


• No history of trauma: Unlike a fracture, Kienböck disease often develops without a specific injury, though some patients report minor, forgotten trauma.

Which tests should I discuss with my doctor?

If you suspect you have Kienböck disease, request a formal evaluation with an orthopedic hand specialist. Initial imaging typically includes standard X-rays, but these may appear normal in the earliest stages. If your symptoms persist despite normal X-rays, ask your physician about an MRI, which is the gold standard for detecting early-stage avascular necrosis before bone collapse occurs.

When should I seek urgent medical evaluation?

If you notice a sudden increase in swelling, visible deformity of the wrist, or an inability to use your hand for daily activities, seek an evaluation promptly. Early intervention for Kienböck disease is critical to preventing permanent joint damage and long-term arthritis.

Next steps

• Consult an orthopedic surgeon who specializes in hand and wrist surgery.
