论文摘要
这项研究的目的是研究股骨颈角，以预测与动态髋关节螺钉（DHS）手术和髋关节畸形相关的并发症。选择了三个样本患者的MRI图像来计算股骨颈角。重建了总共六个股骨头几何形状，并打印了三个维度（3D）型号。颈角的计算都是在计算机模型和3D打印模型中完成的。我们的结果表明，与计算机模型相比，3D打印模型无法确认，并提供了物理测量。与简单的DHS手术相关的颈部角度在129°-139°之间，正常颈角的不统计范围在120°-135°之间。我们的研究表明，特定于患者的3D印刷股头模型为医学教育提供了有用的信息并协助DHS手术。需要基于大型样本量的进一步研究。
The purpose of this study is to investigate the femoral neck angulation for prediction of the complication associated with dynamic hip screw (DHS) surgery and hip deformity. Three sample patients' MRI images were selected to calculate the femoral neck angles. A total of six femur head geometries were reconstructed and three dimensional (3D) models printed. The calculation of neck angles was done in both computer models and 3D-printed models. Our results showed that 3D-printed models achieved high accuracy and provided the physical measurements, when compared to the computer models could not confirm. Neck angulations related to uncomplicated DHS surgery ranged between 129°-139°, and non-deformity of normal neck angles ranged between 120°-135°. Our study indicated that patient-specific 3D printed femoral head models provide useful information for medical education and assist DHS surgery. Further research based on a large sample size is necessary.
