Comparative analysis shows that pedicle screws maintain better spinal fusion stability after bone resection in ankylosing spondylitis, suggesting a strong fixation method.
Under conditions of flexion, extension, and left and right lateral bending, the PS technique provided better biomechanical strength. Whereas, under conditions of left and right rotation, the CBT technique provided better biomechanical strength. Overall, compared to CBT, the current PS technique was sufficiently effective in maintaining spinal fusion stability after bone resection for AS.
