Effect of Spiral CT Three-Dimensional Reconstruction in Guiding Classification and Stability Evaluation of Intertrochanteric Femoral Fracture
Objective:To explore the application value of spiral CT three-dimensional reconstruction in guiding classification and stability evaluation of intertrochanteric femoral fracture(IFF).Methods:A total of 102 patients with IFF who underwent surgical treatment in the hospital from January 2022 to November 2023 were selected as the subjects.All patients underwent X-ray and spiral CT scanning before surgery.The typical imaging manifestations of CT three-dimensional reconstruction were analyzed.With Evans-Jensen classification of intraoperative diagnosis as the gold standard,the accuracy of CT three-dimensional reconstruction in diagnosing the type and stability of IFF was evaluated.Results:In this study,Evans-Jensen classification results showed 17 cases of type Ⅰ,48 cases of type Ⅱ,27 cases of type Ⅲ,6 cases of type Ⅳ,and 4 cases of type Ⅴ.The accuracy of preoperative CT three-dimensional reconstruction for diagnosing the type of IFF was 94.12％(Kappa value=0.864),which was significantly higher than that of preoperative X-ray(84.31％,Kappa value=0.725)(P＜0.05).The detection rates of preoperative CT three-dimensional reconstruction for coronary fractures,incomplete lateral wall,and unstable fracture ends were higher than those of X-ray(P＜0.05).Conclusion:Spiral CT three-dimensional reconstruction is accurate for diagnosing Evans-Jensen type of IFF,and is consistent with intraoperative diagnostic results.At the same time,it can accurately present detailed anatomical changes of IFF.
