The coronal fracture line is acknowledged as a poor prognostic marker in the disease. Other fracture types in the Kienbock's wrist have subsequently been identified.<\/jats:p><jats:p>\n          Questions\/Purposes\u2003The aim is to study the fracture morphology of the lunate in a cohort of patients using computed tomography.<\/jats:p><jats:p>\n          Methods\u2003Patient images were acquired using a set protocol with four-dimensional computed tomography scanning. Images were reviewed by two orthopaedic surgeons and a consultant radiologist. Static and dynamic images were assessed and a fracture map created. The relationship of fracture type to other parameters was then analyzed.<\/jats:p><jats:p>\n          Results\u2003Twenty-three patients were included in the study, including 11 males and 12 females, with a mean age of 43 years. Total frequency of fracture lines in the cohort was coronal \u2013 26, proximal subchondral bone plate type \u2013 24, avulsion \u2013 19, sagittal \u2013 16, and distal subchondral bone plate type \u2013 11. There were statistically significantly more proximal than distal subchondral bone plate fractures (p\u2009=\u20090.03), and more coronal fractures than distal subchondral bone plate fractures (p\u2009=\u20090.01). There were statistically significantly more radiolunate ligament-avulsion types (p &lt;0.001) than other types. The sagittal fracture line through the lunate approximated closely to the ulnar edge of the capitate and the ulnar edge of the radius.<\/jats:p><jats:p>\n          Conclusion\u2003Study on the fracture morphology in the Kienbock's wrist has improved our understanding of the disease pathogenesis. Fracture lines may correspond to loading points, intrinsic and extrinsic ligament avulsions. These fracture types may play a role in disease progression and are important to identify when considering lunate salvage surgery.<\/jats:p>","DOI":"10.1055\/s-0042-1756497","type":"journal-article","created":{"date-parts":[[2022,10,6]],"date-time":"2022-10-06T22:37:04Z","timestamp":1665095824000},"page":"128-134","source":"Crossref","is-referenced-by-count":6,"title":["Lunate Fracture Morphology in Kienbock's Disease\u2014A Computed Tomography Study"],"prefix":"10.1055","volume":"12","author":[{"given":"Simon B.
