Randomized trial investigates fracture risk in osteoporotic spine with metastatic lesions, suggesting increased vulnerability.

This study aims to understand how metastatic lesions affect biomechanical stability in the osteoporotic lumbar spine.
Developed a finite element model of lumbar spine segments (L3-L5) to simulate metastasis effects.
Evaluated scenarios with varying metastasis sizes (0%, 15%, 30%) and bone mineral density (normal, osteoporotic).
Analyzed changes in vertebral bulge and height representing fracture risk indicators.
15% metastasis increased vertebral bulge and height by 178% and 248%, respectively, in normal BMD model.
In the osteoporotic model, 15% metastasis increased vertebral bulge and height by 134% and 174%.
30% metastasis caused additional increases in vertebral bulge and height, highlighting greater instability in normal BMD than in osteoporotic spine.
