Accurate simulation of the herniated cervical intervertebral disc using controllable expansion: a finite element study.

Accurate simulation of the herniated cervical intervertebral disc using controllable expansion: a finite element study. Comput Methods Biomech Biomed Engin. 2020 Dec 17;:1-8 Authors: Liang D, Tu GJ, Han YX, Guo DW Abstract 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. PMID: 33331162 [PubMed - as supplied by publisher]
