ABSTRACT BACKGROUND It remains unclear if minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is comparable to traditional, open TLIF because of the limitations of the prior small-sample-size, single-center studies reporting comparative effectiveness. OBJECTIVE To compare MI-TLIF to traditional, open TLIF for grade 1 degenerative lumbar spondylolisthesis in the largest study to date by sample size. METHODS We utilized the prospective Quality Outcomes Database registry and queried patients with grade 1 degenerative lumbar spondylolisthesis who underwent single-segment surgery with MI- or open TLIF methods. Outcomes were compared 24 mo postoperatively. RESULTS A total of 297 patients were included: 72 (24.2%) MI-TLIF and 225 (75.8%) open TLIF. MI-TLIF surgeries had lower mean body mass indexes (29.5 ± 5.1 vs 31.3 ± 7.0, P = .0497) and more worker's compensation cases (11.1% vs 1.3%, P < .001) but were otherwise similar. MI-TLIF had less blood loss (108.8 ± 85.6 vs 299.6 ± 242.2 mL, P < .001), longer operations (228.2 ± 111.5 vs 189.6 ± 66.5 min, P < .001), and a higher return-to-work (RTW) rate (100% vs 80%, P = .02). Both cohorts improved significantly from baseline for 24-mo Oswestry Disability Index (ODI), Numeric Rating Scale back pain (NRS-BP), NRS leg pain (NRS-LP), and Euro-Qol-5 dimension (EQ-5D) (P > .001). In multivariable adjusted analyses, MI-TLIF was associated with lower ODI (β = −4.7; 95% CI = −9.3 to −0.04; P = .048), higher EQ-5D (β = 0.06; 95% CI = 0.01-0.11; P = .02), and higher satisfaction (odds ratio for North American Spine Society [NASS] 1/2 = 3.9; 95% CI = 1.4-14.3; P = .02). Though trends favoring MI-TLIF were evident for NRS-BP (P = .06), NRS-LP (P = .07), and reoperation rate (P = .13), these results did not reach statistical significance. CONCLUSION For single-level grade 1 degenerative lumbar spondylolisthesis, MI-TLIF was associated with less disability, higher quality of life, and higher patient satisfaction compared with traditional, open TLIF. MI-TLIF was associated with higher rates of RTW, less blood loss, but longer operative times. Though we utilized multivariable adjusted analyses, these findings may be susceptible to selection bias.

Abstract INTRODUCTION Here, we compare minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) to traditional, open TLIF for grade 1 degenerative lumbar spondylolisthesis in the largest study to date by sample size. METHODS We utilized the multicenter, prospective Quality Outcomes Database registry and queried patients with grade 1 degenerative lumbar spondylolisthesis who underwent single-segment surgery with fully minimally invasive or open TLIF methods. Outcomes were compared 24 mo postoperatively: Oswestry Disability Index (ODI), Numeric Rating Scale Back Pain (NRS-BP), NRS Leg Pain (NRS-LP), EuroQol-5D (EQ-5D), North American Spine Society (NASS) Satisfaction Score, cumulative reoperation rate, and return to work (RTW) rate. Multivariate analyses were utilized to adjust for variables reaching P < .20 on univariate analyses. RESULTS A total of 297 patients were included: 72 (24.2%) MI-TLIF and 225 (75.8%) open TLIF. Average age (MI-TLIF: 62.1 vs open TLIF: 59.5 yr) was similar (P = .10). MI-TLIF surgeries were associated with lower body mass index (29.5 ± 5.1 vs 31.3 ± 7.0, P = .0497) and more workman's compensation cases (11.1% vs 1.3%, P = .001). Patients did not differ significantly at baseline for ODI, NRS BP, NRS LP and EQ-5D (P > .05). MI-TLIF was associated with less blood loss (108.8 ± 85.6 vs 299.6 ± 242.2 mL, P < .001), longer operations (228.2 ± 111.5 vs 189.6 ± 66.5 min, P < .001), and a trend toward decreased length of hospitalization (2.9 ± 1.8 vs 3.3 ± 1.6 d, P = 0.08). Discharge disposition to home or home healthcare was similar (94.4% vs 91.1%, P = .38). Both cohorts improved significantly from baseline for 24-month ODI, NRS-BP, NRS-LP, and EQ-5D (P > .001). In adjusted analyses, MI-TLIF was associated with superior ODI (ß = −4.7; 95% CI-9.3 −0.04; P = .048) and EQ-5D (ß = 0.06; 95% CI 0.009-0.11; P = .02). Though trends for superiority were evident for MI-TLIF, they did not reach statistical significance for NRS-BP (P = .06), NRS-LP (P = .07), and NASS Satisfaction (P = .06). Similarly, there was a trend for fewer reoperations following MI-TLIF, though this did not reach statistical significance (1.4% vs 7.6%, P = .10). A higher proportion of MI-TLIF patients were able to RTW following surgery (100% vs 80%, P = .02). CONCLUSION For single-level grade 1 degenerative lumbar spondylolisthesis, MI-TLIF was associated with superior outcomes for disability and quality of life compared with traditional, open TLIF. MI-TLIF was associated with higher rates of RTW and less blood loss, but longer operative times.

Abstract INTRODUCTION The optimal minimally invasive surgical (MIS) approach for lumbar spondylolisthesis is not clearly elucidated. This study compares patient reported outcomes (PRO) following MIS transforaminal lumbar interbody fusion (MI-TLIF) and MIS decompression for degenerative lumbar spondylolisthesis. METHODS A total of 608 patients from the Quality Outcomes Database (QOD) Lumbar Spondylolisthesis Module underwent single-level surgery for degenerative grade 1 lumbar spondylolisthesis of whom 143 underwent MIS [72 MI-TLIF (50.3%) and 71 MIS decompressions (49.7%)]. Surgeries were classified as MIS if there was utilization of percutaneous screw fixation and placement of a Wiltse-plane MIS intervertebral body graft (MI-TLIF) or if there was a tubular decompression (MIS decompression). In total, 24-mo follow-up parameters were collected. PROs included the Oswestry Disability Index (ODI), numeric rating scale (NRS) Back Pain, NRS Leg Pain, EuroQoL-5D (EQ-5D) Questionnaire, and North American Spine Society (NASS) Satisfaction Questionnaire. Multivariate models were constructed adjusting for baseline patient and surgical factors. RESULTS The mean age of the MIS cohort was 67.1 ± 11.3 yr (MI-TLIF 62.1 yr vs MIS decompression 72.3 yr) and consisted of 79 (55.2%) women (MI-TLIF 55.6% vs MIS decompression 54.9%). The proportions reaching 24-mo follow-up were similar (MI-TLIF 83.3% and MIS decompression 84.5%; P = .85). MI-TLIF was associated with higher blood loss (108.8 vs 33.0 mL, P < .001), longer operative times (228.2 vs 101.8 min, P < .001) and length of hospitalization (2.9 vs 0.7 d, P < .001). MI-TLIF was associated with a significantly lower reoperation rate (14.1% vs 1.4%, P = .004). Both cohorts demonstrated significant improvements in ODI, NRS back pain, NRS leg pain, and EQ-5D at 24 mo (P < .001). In multivariate analyses, MI-TLIF was associated with superior ODI change (ß = −7.59; 95% CI [−14.96 to −0.23]; P = .04), NRS back pain change (ß = −1.54; 95% CI [−2.78 to −0.30]; P = .02), and NASS satisfaction (OR = 0.32; 95% CI [0.12-0.82]; P = .02). CONCLUSION For symptomatic, single-level degenerative spondylolisthesis, MI-TLIF was associated with a 10-fold lower reoperation rate and superior outcomes for disability, back pain, and patient satisfaction compared to MIS decompression alone.
