Discussion

Finite element analysis evaluates cement augmentation and vertebroplasty impacts on adjacent segment stability.

Cement augmentation maintains adjacent-level stability with less than 5% change in mechanical metrics.
Prophylactic vertebroplasty reallocates stress, introducing elevated stresses at adjacent vertebral interfaces.
The finite element model was tested under various loading scenarios to assess segmental biomechanical responses.
Understanding these biomechanics informs decision-making, particularly in osteoporotic patients at risk for fractures.

Shin et al. (2025) studied this question.
