Comparison of average pain scores before and after sacroplasty in patients with bilateral or unilateral sacral insufficiency fractures and in patients with underlying sacral lesions
| Lesion type | Pre-treatment average VAS score | Post-treatment average VAS score | p Value |
| Bilateral sacral insufficiency fracture | 9.2±1.1 | 1.9±1.7 | <0.001 |
| Unilateral sacral insufficiency fracture | 8.7±1.5 | 2.5±1.9 | <0.001 |
| Sacral mass or infiltrative lesion | 9.0±0.9 | 2.6±2.4 | <0.001 |
The reduction in the average pain score after sacroplasty was statistically significant (two-tailed t test) in each patient group.
