Kienbock's Disease

Kienböck’s Disease, also termed as Avascular Necrosis of the Lunate, is a condition that occurs due to the loss of blood supply to the lunate. The lunate is the most important of the eight small carpal bones in the wrist. It assists in proper movement and provides support to the joint. Interrupted blood supply blocks the supply of nutrients to the bone and cause it to die, a condition known as Osteonecrosis. Patients with Lupus, Sickle Cell Anemia and Cerebral Palsy are at a higher risk of developing the condition.

Kienböck’s Disease generally progresses through four stages:

  • Stage 1: Symptoms appear similar to that of wrist sprain. X-rays may indicate a possible fracture
  • Stage 2: The lunate bone starts to harden and appear brighter or whiter in X-rays, suggesting that it is dying.
  • Stage 3: The lunate begins to fragment and adjoining bones shift from their original position.
  • Stage 4: The bones surrounding the lunate may start to wear out, making the wrist prone to Arthritis.

Causes Of Kienbock's Disease

  • Repeated trauma to the wrist
  • Skeletal variations such as shorter length of one of the forearm bones
  • Inconsistency in the shape of lunate bone
  • Problems with arteries that supply blood to the lunate

Diagnosis Of Kienbock's Disease

Treatment For Kienbock's Disease

Non-surgical treatment

  • Non-steroidal anti-inflammatory medications may help to provide relief from pain and inflammation during the initial stages of the condition
  • A splint or cast may be recommended by the orthopedic doctor to relieve pressure from the lunate

Surgical treatment

  • Revascularization - It involves using a vascularized graft from an adjacent bone and inserting into the lunate bone. An external fixator may temporarily attached help the lunate heal faster.
  • Proximal row carpectomy - The lunate and two bones on its either side may be removed to relieve pain.
