Fig. 1From: Biomechanical evaluation of different oblique lumbar interbody fusion constructs: a finite element analysisA complete 3D nonlinear finite element model of the lumbar spine. A Capture the skeletal structure of L3-5 lumbar spine and generate the basic 3D contour model; B Construct a surface model with continuity; C Generate a double-segment (L3-5) model; D Generate a single-segment (L4-5) modelBack to article page
