Abstract

The invention relates to a method and a device for establishing a cervical spinal cord simulation model. The method comprises the following steps that MIR scans a cervical spinal cord image of a volunteer, DICOM data are obtained and imported into medical image processing software, the boundary of cervical spinal cord gray matter and white matter and the boundary of white matter and periphery aredivided, a cervical spinal cord cross section model is generated and imported into finite element modeling analysis software to generate a cervical spinal cord three-dimensional finite element model including gray matter, white matter and soft spinal membrane, and parameter setting is conducted. The device comprises a related unit which is used for establishing the cervical spinal cord simulationmodel. The cervical spinal cord three-dimensional finite element model established by the invention comprises gray matter, white matter and soft spinal membrane; the anatomical structure is complete,and parameters are reasonably set, so that the cervical spinal cord injury condition after collision can be simulated, the stress distribution of the spinal cord can be analyzed, the simulation performance is higher, and the clinical guidance significance is higher when the conditions such as collision test and spinal cord injury mechanism research are simulated.

Description

technical field [0001] The invention relates to the field of computer-aided simulation technology and orthopedic scientific research, in particular to a method and device for establishing a simulation model of thoracolumbar burst fracture. Background technique [0002] Cervical hyperextension injury is a common type of cervical spine injury. It is caused by rapid hyperextension and violent load on the cervical spine, accounting for 35%-60% of all kinds of cervical spine injuries. Usually combined with different degrees of spinal cord injury, it brings heavy psychological burden and economic pressure to society and family. The age distribution of patients with cervical hyperextension injury showed bimodal characteristics, one was patients under 30 years old caused by high-energy injuries, and the other was elderly patients with primary cervical spinal stenosis caused by low-energy injuries. [0003] At present, there are many explanations on the relationship between clinical...
