Abstract
BackgroundTo explore the efficacy and safety between posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of lumbar degenerative diseases.MethodsWe searched the literature in Pubmed, Embase, Cochrane Library and Web of Science. The index words were posterior lumbar interbody fusion, PLIF, transforaminal lumbar interbody fusion, TLIF, lumbar interbody fusion, spinal fusion, degenerative disc disease and lumbar degenerative diseases. Primary outcomes were fusion rate and complications. Secondary outcomes were visual analog scale (ΔVAS), Oswestry Disability Index (ΔODI), total blood loss, operation time and length of hospital stay. Review Manager 5.3 and Stata13.1 was used for the analysis of forest plots, heterogeneity, sensitivity and publication bias.Results17 studies were included (N=1562; PLIF, n=835; TLIF, n=727). The pooled data showed PLIF had a higher complications (P= 0.000), especially in nerve injury (p = 0.003) and dural tear (p = 0.005). PLIF required longer operation time (p = 0.004), more blood loss (p = 0.000) and hospital stays (p = 0.006). Surprisingly subgroup analysis showed there was significant difference in complications in patients under 55 (p = 0.000) and Asian countries (p = 0.000). No statistical difference was found between the two groups with regard to fusion rate (p = 0.593),ΔVAS (p = 0.364) andΔODI (p = 0.237).ConclusionsThis meta-analysis showed there were no significant difference in fusion rate, ΔVAS and ΔODI. However TLIF could reduce complications, especially nerve injury and dural tear. Besides, TLIF was associated with statistically significant less blood loss, shorter operation time and shorter length of hospital stay.
