Abstract:
Objective:To compare the biomechanical effects between oblique Ban-pulling manipulation and lumbar erection-rotation manipulation in sitting position in treating lumbar intervertebral disc herniation (LIDH). Methods:A three-dimensional finite element model of L3-S1 was developed to carry out a comparative study between oblique Ban-pulling manipulation and lumbar erection and rotation manipulation in sitting position. The disc protrusion was assumed to be on the rear left of L4 disc, and the manipulations were performed on the right side. The loading process was simulated by two steps. In the first step, only the compression loading was imposed, and in the second step, both the compression loading and axial rotation moment were imposed. The displacement and stress distribution in L4 disc were investigated. Results:The values of stress and displacement in the second step were lower than those in the first step in each manipulation. The stress and displacement differences between the two steps were respectively 1.79 times and 3.03 times larger in oblique Ban-pulling manipulation than those in lumbar erection-rotation manipulation in sitting position. Conclusion: Oblique Ban-pulling manipulation may result in a better biomechanical effect than lumbar erection-rotation manipulation in sitting position for LIDH.
