Abstract:
BACKGROUND:Recent studies have proved the presence of adjacent vertebral fractures after percutaneous kyphoplasty, suggesting that cement leakage may be an important reason. OBJECTIVE:To investigate the effect of bone cement amount during percutaneous kyphoplasty on adjacent vertebral endplate using finite element analysis. METHODS: Three-dimensional finite element pathological model of Osteoporotic vertebral compression fracture was established using finite element analysis, and 10%, 20% and 30% volume of bone cement were filed, respectively. Then the adjacent vertebral endplate stress under the axial compression, anteflexion and rear protraction were analyzed. RESULTS AND CONCLUSION: Compared with that before operation, the adjacent vertebral endplate stress increased with the increase in filed bone cement volume, suggesting that the increased amount of bone cement wil lead to the increasing of adjacent vertebral re-fractures.
