Unilateral extrapedicular versus unilateral and bilateral transpedicular approaches in percutaneous vertebral augmentation for osteoporotic vertebral compression fractures: A meta-analysis.

Aggregate results demonstrated that leakage incidence in the UEA cohort was markedly reduced relative to the BPA cohort (RD:–0.08; 95% CI:–0.14 ~ –0.02; p=0.01), whereas the contrast with the UTA cohort failed to reach significance (RD:–0.01; 95% CI:–0.09 ~ 0.07; p=0.88) (Figure 3, Table III).
