“…The following criteria were used to select studies for inclusion in the meta-analysis: (1) described at least one of the primary outcomes of interest in patients who underwent TLIF with static or expandable cage implantation, (2) published in the English language, and (3) reported follow-up outcomes at a minimum of 6 months. Clinical trials, both non-randomized and randomized, as well as comparative observational studies and case series, were included.…”

“…There are several ways to surgically treat lumbar interbody fusion due to degenerative lumbar diseases; however, each has intrinsic benefits and drawbacks that must be addressed (1)(2)(3). The transforaminal lumbar interbody fusion (TLIF) technique improves surgical results while addressing the drawbacks of existing procedures, such as the risk of vascular damage in anterior lumbar interbody fusion and the amount of neural retraction necessary for posterior lumbar interbody fusion (4)(5)(6).…”

PurposeThis study aimed to provide a direct meta-analysis of the evidence comparing outcomes between expandable cages and static cages in patients with transforaminal lumbar interbody fusion (TLIF).MethodsA search of relevant materials from databases was performed from inception to March 7, 2022. Clinical and radiological outcomes were included.ResultsTen studies (1,440 patients) were included. The anterior disc height and foraminal height for expandable cages were substantially higher than those for static cages at the final follow-up (P < 0.0001; P = 0.05). In comparison with static cages, although not statistically significant, expandable cages showed beneficial results, including an increase in posterior disc height and segmental lordosis. There were no statistically significant differences in segmental lordosis, lumbar lordosis, pelvic parameters, cage subsidence, or fusion rates (P > 0.05). Oswestry disability index scores for expandable cages were substantially lower than those for static cages at the final follow-up (P = 0.0007). Interestingly, although the preoperative visual analog scores for back and leg pain were significantly higher in the expandable group than in the static group (P < 0.0001; P = 0.008), there was no significant difference between the static and expandable groups during the final follow-up (P = 0.51; P = 0.85).ConclusionsExpandable cages are associated with improved functional outcomes and restored postoperative disc and foraminal heights in patients with TLIF. In addition, no statistically significant differences were observed in segmental lordosis, lumbar lordosis, pelvic parameters, cage subsidence, or fusion rate.
