Dr. Mark Yuhas answers your questions about Kienbock’s Disease:

What is Kienbock’s Disease?

Kienbock’s Disease, also known as avascular necrosis of the lunate, is a disease that can result in pain and stiffness in the wrist. The lunate is one of eight small bones in the wrist that give the wrist its complex and unique motion.  “Avascular necrosis” is a lack of blood supply to the bone, which results in bone death. Blood supply is important to all bones to grow, heal, and provide structure and support to the body. Without blood supply, the lunate may not provide the same support and structure needed for proper wrist function.

What is the cause of Kienbock’s Disease? Can it be prevented?

There are several theories about the cause of Kienbock’s Disease, but a single cause has not been identified. Multiple variables are thought to be involved, including a history of wrist trauma. Other contributing factors include variations in anatomy such as the position of the forearm bones at the wrist, the shape of the lunate, and the pattern of blood supply to the lunate. Most of these factors are not able to be controlled by the patient.

There is no way that we know to prevent Kienbock’s Disease. However, it is important to identify this problem as soon as possible in order to prevent progression of the disease which can lead to wrist arthritis. This ultimately can cause pain, stiffness, and decreased function in the wrist.

7 causes of ulnar-sided wrist pain

people, healthcare and problem concept - close up of man suffering from pain in hand oe wrist at home

The “pinkie” side of the wrist is also known as the ulnar side. Pain on this side can be very common. It can result from injury to bones, cartilage, ligaments or tendons. Due to this wide range of causes, it can be difficult to determine why the pain is happening. Here are some possible causes of ulnar-sided wrist pain:

  1. Wrist fracture
  2. Arthritis of the joint(s) between the bones
  3. Ulnar Impaction Syndrome (when the ulna is longer than the radius, which can cause it to “bump into” the smaller wrist bones)
  4. Inflammation or irritation of the tendons that bend and extend the wrist
  5. Triangular Fibrocartilage Complex Injury (TFCC) (when the connection between the ulna bone and other structures in the wrist is torn by an injury or frayed over time)
  6. Nerve injury or compression
  7. Tumors, most commonly ganglion cysts, that are benign
