Kienbӧck’s disease is considered an uncommon condition that affects approximately 0.0066% of the population. The population most commonly affected are men between the ages of 20 and 40 years old. Kienbӧck’s disease is defined by osteonecrosis of the lunate carpal bone.
The lunate is found within the midportion of the proximal carpal row and lies adjacent to the distal radius. There are also articulations with the scaphoid, capitate, and hamate. The term Kienbӧck comes from Dr.
Robert Kienbӧck, an Austrian radiologist who identified the condition based on radiographs in 1910. Joint articulations of the lunate The pathophysiology for patients developing Kienbӧck’s is controversial. One prevailing etiology is secondary to intra-osseous venous thrombosis, which can form and lead to an “intra-osseous compartment syndrome”.
The compartment syndrome may lead to necrosis of the subchondral bone. There are also theories regarding the shape and location of the lunate acting as risk factors for developing necrosis. The most common site for the development of necrosis within the lunate is within the proximal articular surface.

There may also be complaints of hand and wrist swelling, a decrease in wrist range of motion, and weakness in the hand. There does not need to be an injury or trauma that triggers the pain and it typically occurs spontaneously.
If you are experiencing symptoms that may be related to kienbӧck disease, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
