- W2351271364 abstract "Objective To test the biomechanical stiffness of the operation model of spinal tuberculosis constructed by monosegment fixation with short pedicle screw after interbody bone graft.Methods Ten fresh calf spines(T12-L3) were made into the mechanical test models of simulating spinal tuberculosis with being cut off the L1-2 intervertebral discs and the adjacent end plates,iliac graft in situ and posterior monosegment fixation with short pedicle screw.Test the stability of the models of the control group and the groups with and without bone graft in axial compression,lateral bending,flexion-extension and rotation.Results The relative range of movement of(RROM) of the models with bone graft was significantly lower than that of the ones without bone graft in axial compression,lateral bending and flexion-extension(P0.05).However,no significant difference was found between them in rotation(P0.05).In the axial compression,the stress along the posterior internal fixation in group without bone graft was significantly increased than that in group with bone graft(P0.05).Conclusion Interbody bone graft could increase the stability of the model in axial compression,lateral bending,flexion-extension,and decrease the load-sharing on internal fixation.Otherwise,it effects little in rotation without interbody fusion." @default.
