Abstract:

Objectives To investigate the feasibility and value of digitalized visualization in the fracture classification of calcaneal fracture. Methods Seventeen cases of calcaneal fractures underwent multidetector CT scan. Three-dimensional reconstruction of visible models of these fractures were performed with the mimics 10.0 software on the basis of CT raw data. Two Senior orthopaedics surgeons class the fractures by Sander's criteria and digitalized criteria. The reliability between the criteria was compared using Kappa value. Results 17 three-dimensional visible models were established. The anatomic site, direction and degree of dislocation of fracture were demonstrated accurately. The Kappa value of digitalized criteria was 0.795(0.691~0.874), which was 0.641(0.591~0.701)in Sander's criteria. Conclusion Digitalized three-dimensional reconstruction can give intuitive and clear result in calcaneal fracture and classification. Its reliability is high. It will provide precise imaging basis for surgical plan.
