What is Kienbock's Disease?

Kienbock's Disease affects the blood supply to the lunate, a small bone in the wrist. This condition causes pain, swelling, and limited mobility in its early stage. If it progresses, it can collapse the bone. Kienbock's disease progresses in four stages:

  • Stage One: Symptoms which mimic wrist sprain develop.
  • Stage Two: The lunate bone begins to harden.
  • Stage Three: The lunate bone begins to deteriorate.
  • Stage Four: Surface of nearby bones is affected. Arthritis may develop.


  • Pain and swelling in the wrist
  • Stiffness and limited range of motion
  • Weakened grip strength

Treatment Options

During the initial stage of the disease, treatment options include immobilization and anti- inflammatory medication to reduce swelling and pain. If symptoms persist, or if the disease progresses, surgical treatments may be available.

Available surgical treatments include:
  • Bone grafting: to restore blood supply to the area
  • Joint Leveling: used when the bones in the forearm are uneven, causing pressure on the lunate
  • Proximal Row Carpectomy (removal of deteriorated bones in the wrist): to relieve pain and swelling while maintaining partial mobility
  • Bone Fusion: used in severe cases after wrist bones have deteriorated. This procedure offers relief from pain and swelling, though range of motion in the wrist will be limited.
