The Volumetric Analysis of Cement in Vertebroplasty

Abstract

It is suggested that fraction is superior to volume for predicting outcome on the T11-L1 level and an amount of cement should be determined in terms of FBV and fraction according to the treated level. A lower fraction than required for the restoration of mechanical property was enough to obtain pain relief. Intradiscal leakage on the L2-L4 level may be inevitable to obtain appropriate mechanical properties in the case of severe endplate breakdown connected with the disc space. Smaller volume is needed to avoid an adjacent fracture on the L2-L4 level. Although we did not know the reason why there was a difference among the treated level groups, one thing that is certain is the fact that level-specific approaches may be necessary for good outcome in terms of volume, fraction and FBV.
