Depending on the severity, Kienbock's Disease can be classified as:

  • Stage 1: Symptoms may become similar to wrist sprain. X-rays may not be able to diagnose the condition.   
  • Stage 2: Insufficient blood supply can lead to hardening of the bones. This stage is known as Sclerosis.
  • Stage 3: Breaking of the lunate bone into fragments which can cause the surrounding bones to dislocate.
  • Stage 4: This is the most severe condition which can further lead to the development of Arthritis.

Treatment For Kienbock's Disease

Non-surgical treatment

  • Medications: Anti-inflammatory medications may be prescribed by the doctor to ease pain. Cortisone injections may be administered in case of severe pain.  
  • Rest: Sufficient rest must be provided to the affected area. Avoid activities that require excessive use of wrist.  
  • Hand therapy: The physical therapist may recommend certain exercises to improve strength and flexibility of the wrist joint.

Surgical treatment

  • Joint leveling: This procedure is recommended if the forearm bones are different in length. A bone graft may be used to increase the length of a bone. As another option, the surgeon may remove a section of the bone to shorten its length.
  • Fusion: The surgeon may perform partial or complete fusion depending on the severity of the condition. In this procedure, surrounding bones in the wrist may be joined to release pressure from the lunate.    
  • Revascularization: In this procedure, surgeon may remove a portion of bone along with blood vessels and insert it into the lunate. This may help in restoring the blood supply to the affected bone.
  • Arthroplasty: The procedure involves replacing the lunate bone in the wrist with an artificial implant to increase the blood supply and alleviate pain.
