Progress in clinical application of fracture mapping based on CT three-dimensional reconstruction

CT three-dimensional reconstruction has been widely used in the diagnosis and classification of fractures. Fracture mapping based on the CT three-dimensional reconstruction can visually display the morphology of fracture lines by drawing a fracture model, showing the starting and ending points, progress and area of the fracture lines. It provides a new method for diagnosis and classification of fractures, operative plan and design of implants for fractures, statistic analyses of predominant fracture sites, and developing standardized fracture models. This review gives a brief introduction of the research progress at home and abroad in fracture mapping for scapular fracture, pilon fracture, ulnar coronoid fracture, tibial plateau fracture, radial head fracture, intertrochanteric lateral wall fracture and acetabular quadrilateral surface fracture, summarizes the likely sites in the above fracture models and clinical application of fracture mapping in fracture classification, and discusses the prospects and problems of this technique in clinical application.
