Figure 6From: Four lateral mass screw fixation techniques in lower cervical spine following laminectomy: a finite element analysis study of stress distribution Stress distribution of the four different LSF techniques under different conditions. According to the indicator diagram, red area means the stress concentration, while blue area shows the stress dispersion. From A to D: Magerl group, Roy-Camille group, Anderson group and An group. From 1 to 6: flexion, extension, left lateral bending, right lateral bending, left axial rotating and right axial rotating conditions.Back to article page
