Results: The MRI sign of lumbar spondylolysis was irregular bony defects in the pars interarticularis of the neural arch, spondylolisthesis, elongated anterior posterior diameter of the canal, deformity of disk and neural foramen. 结果:24例腰椎峡部裂的MRI表现为腰椎峡部出现不规则状骨性缺损、脊椎滑脱、椎管前后径增大、椎间盘变形、椎间孔变形等。
Results: The model can offer the optimal distance between the neural arch of atlas and axis. 结果:回归模型的计算机界面能够提供寰枢椎弓融合的最佳距离。
Artificial Neural Networks Method for Determining Approximate Optimum Shape of Arch Dam 拱坝近似优化的人工神经网络方法
Our study begins with a practical problem we encountered which is how we select the optimal neural arch interval in posterior atlantoaxial fusion, and tends to focus on the differences in relative stability under three-dimensional motion ( rotational translation). 本研究从解决寰枢后路融合手术中神经弓融合距离的实际问题入手,重点考察三维运动(三向转动)对该关节稳定性的影响。
