Article Figures & Data
Figures
- Fig 1.
Graph shows mean pain scores throughout follow-up. Values shown are mean pain scores for each of the time points. Error bars indicate standard error of the mean.
- Fig 2.
Graph shows cement volume injected as a function of vertebral level treated. Volume of cement increases with treatment of more caudal vertebrae.
