摘要
目的:股骨上段参数与临床损伤的预防、治疗密切相关,通过比较分析应用三维重建技术测量与直接测量的结果,探索活体骨骼形态参数准确测量的方法。方法:取140例干性股骨标本进行实际测量其颈干角、前倾角、股骨头直径、股骨头高度、股骨颈直径,记录结果。再将此140例干性股骨标本进行CT扫描,经建模软件Mimics17.0三维重建,再由软件Geomagic 12.0、Hypermesh 11.0进一步处理后,对股骨近端的解剖参数进行测量。将三维重建测量结果与实际测量结果及以往研究结果进行统计分析。结果:以上两种方法测量结果基本一致,符合正态分布,三维重建法测量结果更集中;与以往研究比较,差异无统计学意义(P>0.05)。结论:基于CT数据应用三维重建技术进行股骨形态参数测量,结果准确、可信,可以应用于临床,有助于损伤的个体化治疗。
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.
