The risk of new vertebral fracture after percutaneous vertebral augmentation in patients suffering from single-level osteoporotic vertebral compression fractures: A meta-analysis and systematic review.

Background: To investigate the effect of Vertebral augmentation (VA) in the treatment of single-level osteoporotic vertebral compression fractures (OVCFs) on new vertebral fractures.

Methods: Electronic databases Pubmed, Embase, and the Cochrane Central Register of Controlled Trials were searched from database creation to 5 September 2022. Eligible studies had to use VA as an intervention and conservative treatment as a control group. Studies had to explicitly report whether new vertebral fractures occurred during follow-up. Data were extracted by multiple investigators. Data were pooled using random or fixed effects models depending on the degree of heterogeneity.

Results: Of the 682 articles screened, 7 met the inclusion criteria and were included in the analysis, giving a total of 1240 patients. Meta-analysis showed that VA (OR = 2.10, 95% CI: 1.35-3.28, P = .001) increased the risk of new postoperative vertebral fractures compared with conservative treatment. Subgroup analyses showed that the risk was greater in the group with a follow-up time greater than 1 year (OR = 2.57, 95% CI: 1.06-6.26, P = .001). Compared with conservative treatment, VA (OR = 2.17, 95% CI: 1.23-3.82, P = .007) increased the risk of postoperative adjacent vertebral fracture.

Conclusion Subsections: VA is associated with an increased risk of new vertebral fractures and adjacent vertebral fractures following single-level OVCFs. With longer follow-ups, new vertebral fractures may be more significant. Clinical surgeons should pay attention to long-term postoperative complications and choose treatment carefully.
