- Abstract: Objective To investigate the diagnostic value of 62-slice spiral CT and its post-processing techniques for tibial plateau fracture(TPF)and its influence on treatment regimens selection.Methods A total of 173 TPF patients diagnosed and treated in our hospital from January 2021 to December 2022 were included,and the diagnostic accuracy,classification diagostic accuracy and fracture collapse degree accuracy of X-ray and CT scans were compared,with surgical and pathological diagnosis as the gold standard.Results CT and its post-processing technique can more clearly show the direction of fracture line,the displacement direction of fracture fragments and the collapse degree of articular surface than X-ray.The fracture morphology of 171 patients seen during the operation was consistent with CT and its post-processing images.The diagnostic accuracy of X-ray for TPF was 93.64%,which was lower than that of CT and its post-processing techniques(98.84% ),and the difference was statistically significant(χ2=6.474,P=0.011).The overall accuracy of X-ray in evaluating the degree of fracture collapse was significantly lower than that of CT 3D reconstruction(65.32% vs.90.75%;χ2=32.644,P<0.001).The total accuracy of CT and its post-processing techniques for TPF Schatzker classification(97.69% )was higher than that of X-ray(88.44% ),and the difference was statistically significant(χ2=11.462,P=0.001).Different CT reconstruction models had statistically significant difference on the total accuracy of TPF Schatzker classification diagnosis(χ2=40.647,P<0.001),and the diagnosis accuracy of volume reconstruction was the highest(96.53% ).Conclusion The application of CT and its post-processing techniques can effectively evaluate TPF,articular surface collapse and fracture classification,and provide imaging reference for clinical decision-making.
