Abstract:
Objective To compare the diagnostic reliability of AO classification and Evans-Jensen classifications in X ray film and three-dimensional CT reconstruction images intertochanteric fractures, and explore advantage of the three-di?mensional CT. Methods A retrospective study was performed to evaluate 54 patients with intertochanteric fractures. Three orthopaedic surgeons were asked to make assessment of fracture classifications using X ray film and the three-dimen?sional CT images. Agreement test was performed to evaluate interobserver and intraobserver reliability for fracture classifica?tion. Results When X ray film was used, mean Kappa values of interobserver reliability for AO and Evans-Jensen classifi?cations between three surgeons were 0.597 and 0.571, that was medium consistency. While using three-dimensional CT to AO classification, lower Kappa value was 0.411, medium consistency. Evans-Jensen classification, Kappa value was 0.704, highly consistency. Each surgeon respectively using X ray film and three-dimensional CT, the mean Kappa values of AO and Evans-Jensen classification were 0.464, medium consistency and 0.191 (0.160-0.233), weak consistency. Conclusion Both classifications based on X ray film show moderate consistency, using three-dimensional CT does not improve the consis?tency of AO classification. The three-dimensional CT is not applicable in Evans-Jensen classification.
