Abstract:Objective: Because the morphological parameters of femur are closely related to clinical injuries, this study aims to find a new method for measuring the parameters of the femur by comparative analysis of 3D reconstruction techniques and the direct measurement. Methods: The neck shaft angle, femoral neck anteversion, the diameter and height of the femoral head, and the diameter of femoral neck of 140 cases of dry femoral specimens were actually measured and recorded. Then these 140 cases of dry femur specimens underwent CT scan. After software Mimics 17.0 3D reconstruction, and the image analysis software Geomagic 12.0, Hypermesh 11.0 processing, anatomical parameters of the proximal femur were measured. The measurement results of the 3D reconstruction and the direct measurement and the previous studies were statistically analyzed. Results: The results of the above two methods for the femur parameters measurement are basically same, consistent with the normal distribution. It is shown no significant difference compared to previous studies, in spite of 3D reconstruction method is more concentrated. Conclusion: Based on CT data, 3D reconstruction technique measuring the femoral morphological parameters is accurate and credible, and it could be applied in clinical practice and contributed to the individualized injury treatment.
