Abstract: Objective To investigate the biomechanical influence of different lower lumbar spine facet tropism(FT)criteria on the stress on the L4-L5 segment. Methods Symmetric and facet tropism finite element models of L4-L5 segment were created, including symmetrical model FT 0° model(50° facet joint angle at the bilateral side), FT 5° model(a 55° facet joint angle at the left side and a 50° facet joint angle at the right side), FT 10° model(a 60° facet joint angle at the left side and a 50° facet joint angle at the right side), FT 15° model(a 60° facet joint angle at the left side and a 50° facet joint angle at the right side). Seven stress states were simulated, including forward flexion, extension, left flexion, right flexion, left rotation, right rotation pure moments and anterior shear force. Changes of the maximum intradiscal pressure, maximum vertebral body movement and maximum facet contact force in each model under each stress state were analyzed. Results Changes of the maximum intradiscal pressure were consistent with the trend of maximum vertebral body movement. Under the force of anterior shear, flexion, extension, lateral bending and rotation, the maximum intradiscal pressure was FT 15°>FT 10°>FT 5°>FT 0°. The maximum intradiscal pressure was greater than the more sagittal side(right side)when the FT model was rotated to the more coronal side(left side). Under anterior shear force, flexion, extension, lateral bending and rotation, the maximum facet contact force was FT 15°> FT 10°> FT 5°>FT 0°. Under anterior shear force and flexion, the maximum contact force of the asymmetric joint was significantly increased. Conclusion The maximum intradiscal pressure in the FT model of the lower lumbar spine is consistent with the change of vertebral body movement, which increases with the increase of the degree of asymmetry of the facet joint angle between the left side and right side. But the facet tropism of 5° will not cause significant changes in the maximum intradiscal pressure and maximum vertebral body movement. The maximum contact force increases with the degree of asymmetry of the facet joint angle.
