【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Geomagic12.0、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(P0.05)。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: the parameters of upper femur are closely related to the prevention and treatment of clinical injury. Methods: the neck angle, anteversion angle, femoral head diameter, femoral head height and femoral neck diameter were measured in 140 cases of dry femur. The CT scans of 140 dry femur specimens were performed, and the anatomical parameters of the proximal femur were measured by the software Geomagic 12.0 HyperMesh 11.0 after the 3D reconstruction with Mimics17.0 software. The three-dimensional reconstruction measurement results, the actual measurement results and the previous research results are statistically analyzed. Results: the results of the above two methods were basically consistent with normal distribution, and the results of 3D reconstruction were more concentrated, and there was no significant difference between the two methods compared with previous studies (P 0.05). Conclusion: using 3D reconstruction technique to measure the morphological parameters of femur based on CT data, the results are accurate, reliable, and can be used in clinic, which is helpful for individualized treatment of injury.
