Aim:
To compare the incidences of cement leakage between unilateral and bilateral percutaneous vertebral augmentation (PVA) in the treatment of osteoporosis vertebral compression fractures, a meta-analysis was performed.
Material And Methods:
Pertinent studies were identified by a search of the PubMed, Embase, and Web of Science databases up to December 2020. The risk ratio (RR) or weighted mean difference (WMD) was applied to combine the results, and a randomeffects or a fixed-effects model was used to pool the results depending on the heterogeneity among studies. Publication bias was estimated using Egger's regression asymmetry test.
Results:
A total of 16 trials (including 9 randomized controlled trials and 7 cohort studies) met the inclusion criteria and were included in this meta-analysis. The incidences of cement leakage were similar between the bilateral PVA and unilateral PVA groups (RR=0.80, 95%CI: 0.57, 1.11; p=0.182) but unilateral PVA required less cement volume (WMD=-1.34 ml, 95%CI: -1.87, -0.81; p < 0.001). Subgroup analysis revealed that the incidence of cement leakage was significantly lower in the unilateral PKP group than in the bilateral PKP group (RR=0.65, 95%CI: 0.44, 0.97; p=0.034).
Conclusion:
The incidences of cement leakage were similar between unilateral and bilateral PVA, but unilateral PVA required less cement. More large-scale studies are needed to verify our findings.
