Definition – avascular necrosis of the lunate
Clinical Significance – most often results from trauma with biomechanical and vascular abnormalities that lead to progressive bone death. Patients will report wrist pain with decreased range of motion and grip strength. MRI is best for early diagnosis and treatment depends on the stage of disease using the Lichtman Classification system.
History – Named after Robert Kienböck (1871-1953), who was an Austrian radiologist and received his medical doctorate from the University of Vienna in 1895. He would explore the new and blossoming field of radiology before becoming the head of the radiological department at Vienna General Hospital before becoming professor of radiology in 1926. He was a pioneer in the use of x-rays for medical diagnosis and would co-found the Vienna Radiology Society in 1923. He would publish his eponymous condition in 1910 in his treatise Über traumatische Malazie des Mondbeins und ihre Folgezustände (Traumatic malacia of the lunate and its consequences).
