Object Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) has the potential advantage of minimizing soft-tissue damage and reducing recovery time compared to open procedures. A steep learning curve has been described for the technique. The aim of the present study was to define the learning curve that describes the progress of a single surgeon performing the MI-TLIF. Methods One hundred fifty consecutive patients with degenerative lumbar disease who underwent 1- or 2-level MI-TLIF were included in the study. Operative time, corrected operative time per level, and complications were analyzed. The learning curve was assessed using a negative exponential curve-fit regression analysis. Results One hundred ten patients underwent 1-level and 18 patients underwent 2-level MI-TLIF; the remaining 22 underwent a single-level procedure plus an ancillary procedure (decompression at adjacent level, vertebral augmentation through fenestrated pedicle screws, interspinous device at adjacent level). Negative exponential curves appropriately described the relationship between operative time and experience for 1-level surgery and after correction of operative time per level (R2 = 0.65 and 0.57). The median operative time was 140 minutes (interquartile range 120–173 minutes), and a 50% learning milestone was achieved at Case 12; a 90% learning milestone was achieved at Case 39. No patient required transfusion in the perioperative period. The overall complication rate was 12.67% and the most frequent complication was a dural tear (5.32%). Before the 50% and 90% learning milestones, the complication rates were 33% and 20.51%, respectively. Conclusions The MI-TLIF is a reliable and effective option for lumbar arthrodesis. According to the present study, 90% of the learning curve can be achieved at around the 40th case.

BACKGROUND: Minimally invasive transforaminal lumbar interbody fusion (TLIF)—or MI-TLIF—has been increasing in prevalence compared with open TLIF (O-TLIF) procedures. The use of MI-TLIF is an evolving technique with conflicting reports in the literature about outcomes. OBJECTIVE: To investigate the impact of MI-TLIF in comparison with O-TLIF for early and late outcomes by using the Visual Analog Scale for back pain (VAS-back) and the Oswestry Disability Index (ODI). Secondary end points include blood loss, operative time, radiation exposure, length of stay, fusion rates, and complications between the 2 procedures. METHODS: During August 2014, a systematic literature search was performed identifying 987 articles. Of these, 30 met inclusion criteria. A random-effects meta-analysis was performed by using both pooled and subset analyses based on study type. RESULTS: Our meta-analysis demonstrated that MI-TLIF reduced blood loss (P < .001), length of stay (P < .001), and complications (P = .001) but increased radiation exposure (P < .001). No differences were found in fusion rate (P = .61) and operative time (P = .34). A decrease in late VAS-back scores was demonstrated for MI TLIF (P < .001), but no differences were found in early VAS-back, early ODI, and late ODI. CONCLUSION: MI-TLIF is associated with reduced blood loss, decreased length of stay, decreased complication rates, and increased radiation exposure. The rates of fusion and operative time are similar between MI-TLIF and O-TLIF. Differences in long-term outcomes in MI-TLIF vs O-TLIF are inconclusive and require more research, particularly in the form of large, multi-institutional prospective randomized controlled trials.

Abstract BackgroundWith the rapid development of less-invasive techniques, the percutaneous endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) as a novel minimal surgical technique for treating lumbar spondylolisthesis in recent years. To compare the preliminary efficacy of Endo-TLIF with that of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for the treatment of lumbar spondylolisthesis.MethodsBetween May and August 2019, 62 patients with single-segment lumbar spondylolisthesis treated by a single surgeon were enrolled in this clinical study: there were 32 patients in the Endo-TLIF group and 30 patients in the MIS-TLIF group. Perioperative parameters, including operative time, estimated blood loss (EBL), interoperative fluoroscopy time, ambulation time and operative complications, were recorded. At preoperatively, 1 week, 3 months, 6 months and 12 months postoperatively, the results of clinical metrics such as the Visual Analog Scale (VAS) for back pain, the Oswestry Disability Index (ODI) and the Japanese Orthopaedic Association (JOA) score were obtained and used to compare early outcomes between the two groups. Postoperative fusion rates were assessed by CT scans 12 months after surgery.ResultsNo significant differences were found in the demographic data, including sex, age, body mass index (BMI), segment distribution and spondylolisthesis severity, between the two groups. Compared with MIS-TLIF group, Endo-TLIF group had a similar operative time (202.6±31.4 minutes), less intraoperative blood loss (73.0±26.0 ml) and a shorter ambulation time (1.6±0.6 days) but had a longer duration of X-ray radiation (46.3±5.1 seconds). The postoperative VAS scores for back pain as well as the ODI and JOA scores were improved compared with the preoperative scores in the two groups, but the Endo-TLIF group showed more significant improvement in the early follow-up. There were no significant differences in terms of the interbody fusion rate between the two groups. However, no obvious postoperative complications were observed in the study.ConclusionEndo-TLIF technique shows relatively better outcomes compared with MIS-TLIF in terms of an early curative effect, especially one week and six months postoperatively.
