【摘要】：目的：探讨数字化三维模介导的三维空间法在股骨前倾角测量中的运用,为临床测量股骨颈前倾角提供高效方法。方法：招募健康志愿者10名,其中男5例,女5例；年龄18-60岁,平均43岁。作双侧股骨CT扫描,并将CT数据导入Mimics 17.0软件进行三维重建建模。分别采用传统photoshop法和三维空间法测量股骨颈前倾角,比较两种方法所测的前倾角值和测量时间。结果：photoshop法测得10名患者股骨前倾角平均值为(16.98±4.16)。,三维空间测得股骨颈前倾角平均值为(16.95±4.17)。,两种方法所测角度相比差异无统计学意义(P=0.553), photoshop法测量所需平均时间为(1231.50+152.77)秒,三维空间法测量所需平均时间为(590.00±37.18)秒,两种测量方法所需时间相比差异有统计学意义(P=0.000)。结论：三维空间法和传统photoshop法测量股骨颈前倾角均能得到精确的前倾角值,但与传统photoshop法相比,三维空间法大大减少了测量的时间,提高了测量效率。
[Abstract]:Objective: to explore the application of three dimensional spatial method mediated by digital 3D model in the measurement of femoral anteversion angle, and to provide an effective method for clinical measurement of femoral neck anteversion angle. Methods: ten healthy volunteers were recruited, including 5 males and 5 females, aged 18-60 years, with an average age of 43 years. The CT scan of bilateral femur was performed, and the CT data were imported into Mimics 17.0 software for 3D reconstruction modeling. The anteversion of femoral neck was measured by traditional photoshop method and three dimensional spatial method, and the anteversion angle and time were compared between the two methods. Results the average femoral anteversion of 10 patients was 16.98 卤4.160.The average of femoral neck anteversion was 16.95 卤4.170.There was no significant difference between the two methods, and the average time of photoshop was 1231.50 152.77 seconds. The average time required for 3D measurement was 590.00 卤37.18 seconds, and the difference between the two methods was statistically significant. Conclusion: both three-dimensional space method and traditional photoshop method can obtain accurate antegrade angle of femoral neck, but compared with traditional photoshop method, three-dimensional space method can greatly reduce the measuring time and improve the measuring efficiency.
