Verification of ideal screw size, trajectory, and shape for single and double endplate penetrating screw trajectories using osteoporotic vertebral body models based on the finite element method
Fixation strength improved with larger screw diameters in DEPST. S-DEPST provided additional fixation due to rim penetration. ETS may offer a higher fixation strength and warrants further validation.
