Abstract: Objective To investigate the evaluation of femoral neck anteversion using the digital three-dimensional model induced determination method.Methods Ten healthy volunteers,including five men and five women,aged 18-60 years (mean,43 years) were recruited.Bilateral femur CT scan was taken and processed with Mimics 17.0 software to build the three-dimensional model of the femur.Traditional Photoshop and three-dimensional reconstruction techniques were separately applied to determine the femoral neck anteversion.Anteversion angle and measurement time determined with the two methods were compared.Results Anteversion angle was (17.0 ± 4.2) ° based on the Photoshop method and was (17.0 ± 4.2) ° based on the three-dimensional method (P ＞ 0.05).Measuring time was (1,231.5 ± 152.8) sec with the Photoshop method and (590.0 ± 37.2) sec with the three-dimensional method (P ＜ 0.01).Conclusion Both methods provide accurate measuring of the femoral neck anteversion,but three-dimensional measurement spends far less time resulting in improved measure efficiency.
