  1. Data are presented as mean ± SD. The groups were compared by repeated measures analysis of variance (ANOVA). Bonferroni correction was used to correct multiple comparisons. Group P: PVP group; Group PF: PVP combined with FB group
  2. Abbreviations: VAS visual analog scale, PVP percutaneous vertebroplasty, FB facet joint block
  3. #P < 0.05, vs pre-operation in the same group; *P < 0.05, vs Group P in the same time
