Abstract

Highlights: Kienböck's disease corresponds to osteonecrosis of the lunate and leads to wrist degenerative joint disease in the absence of treatment. Better understanding of its physiopathology allows to explore its different facets with cross-sectional imaging. These provide essential diagnostic evidence concerning respectively the viability of the lunate, its structure and the cartilage status in wrist joints. This information is essential for the choice of the most appropriate treatment option and post-treatment follow-up. Abstract: The management of Kienböck's disease is complex and constantly evolving in parallel with progress in the understanding of the pathophysiological mechanisms of this condition. Cross-sectional imaging techniques have an essential role in the diagnosis and prognostic assessment of this disease. CT allows the optimal study of the morpho-structure of lunate bone. MRI makes it possible to study bone marrow viability. As for CT arthrography, it allows to evaluate accurately articular cartilage of the different carpal joints. The evaluation of these different aspects of Kienböck's disease is essential for optimal treatment selection. Cross-sectional imaging also has an interest in post-treatment follow-up, by having a prognostic value and allowing the identification of post-operative complications. The purpose of this article is to review the contribution of cross-sectional imaging in the assessment of Kienböck's disease before and after treatment according to the most common surgical procedures. Pathophysiological mechanisms, predisposing factors, the different classifications and their interests will be discussed.
