Kienböck’s disease is a rare, debilitating condition that can lead to chronic pain and dysfunction. It happens when one of the eight small carpal bones in the wrist – the lunate bone, more specifically – becomes damaged because there is no blood supply.
It is also known as avascular necrosis of the lunate, or osteonecrosis of the lunate.
You may wonder if you suffer from Kienböck’s Disease if you experience the following:
- Swelling, pain, and stiffness in the wrist
- Clicking, or clunking in the wrist
- Weakening of grip strength
- Tenderness directly over the lunate bone
