Figure 1From: Four lateral mass screw fixation techniques in lower cervical spine following laminectomy: a finite element analysis study of stress distribution The procedure to establish the intact 3D FE model: A: the primary model of the normal lower cervical vertebra, B: the intact model of the lower cervical spine after recovering the physiological lordosis, C: the meshed finite element of the lower cervical spine, D: the model to simulate physiological movement.
