Comparison of clinical efficacy and surgeon’s neck flexion time between unilateral biportal endoscopic lumbar fusion versus minimally invasive transforaminal lumbar fusion in the treatment of single-level lumbar degenerative diseases: a single center retrospective study

Table 4 Comparison of ODI between group MIS and group UBE at different time

Notes: 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 MIS: MIS-TLIF group; Group UBE: UBE-LIF group; vs. pre-operation in the same group, ^aP < 0.05; vs. Group UBE in the same time, ^bP < 0.05
Abbreviations: ODI, Oswestry Disability Index; MIS-TLIF, minimally invasive transforaminal lumbar fusion; UBE-LIF, unilateral biportal endoscopic lumbar fusion
