Expansions were carried out in finite element (FE) models of disc hernia including symmetric (median, lateral, paramedian) and asymmetric types. In all models, lubricous disk bulging that applied a linear compression to the anterior part of the cord was observed at the posterior surfaces of the expansion zone, respectively. The shape and position of protrusions varyed with the temperature, magnitude, and location of expanding elements. The geometric deformation and stress distribution of the spinal cord increased as the extent of compression grew. This method is in possession of enormous potential in promoting further individualized research of cervical spondylotic myelopathy.
对椎间盘疝的有限元（FE）模型进行了扩展，包括对称（正中、外侧、旁正中）和不对称类型。在所有模型中，在扩展区域的后表面观察到了滑润盘膨出，其对索前部施加线性压缩。凸起的形状和位置随扩展元件的温度、大小和位置而变化。随着压缩程度的增加，脊髓的几何变形和应力分布增加。这种方法在促进颈椎脊髓病的进一步个体化研究方面具有巨大的潜力。
