Study Design: A systematic review and meta-analysis. Objectives: To evaluate clinical and radiographic outcomes, and perioperative complications of oblique lateral interbody fusion (OLIF) for adult spinal deformity (ASD). Methods: We performed a systematic review and meta-analysis of related studies reporting outcomes of OLIF for ASD. The clinical outcomes were assessed by visual analogue scale (VAS) and Oswestry Disability Index (ODI). The radiographic parameters were evaluated by sagittal vertical axis (SVA), pelvic tilt (PT), sacral slope (SS), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence-lumbar lordosis (PI-LL), Cobb angle and fusion rate. A random effects model and 95% confidence intervals (CI) were performed to investigate the results. Results: A total of 16 studies involving 519 patients were included in the present study. The mean difference of VAS-back score, VAS-leg score and ODI score before and after surgery was 5.1, 5.0 and 32.3 respectively. The mean correction of LL was 20.6°, with an average of 6.9° per level and the mean correction of Cobb was 16.4°, with an average of 4.7° per level. The mean correction of SVA, PT, SS, TK and PI-LL was 59.3 mm, 11.7°, 6.9°, 9.4° and 20.6° respectively. The mean fusion rate was 94.1%. The incidence of intraoperative and postoperative complications was 4.9% and 29.6% respectively. Conclusions: OLIF is an effective and safe surgery method in the treatment of mild or moderate ASD and it has advantages in less intraoperative blood loss and lower perioperative complications.

Abstract Background The minimally invasive treatment for adult degenerative scoliosis has become more and more popular. The purpose of this study was to evaluate the efficiency of stand-alone oblique lateral interbody fusion for the treatment of adult degenerative scoliosis in terms of clinical and radiological outcomes. Methods A total of 18 patients with ADS who underwent stand-alone OLIF in our hospital from July 2017 to May 2018 were enrolled in the study. Clinical evaluations were performed with visual analogue scale (VAS) and Oswestry Disability Index (ODI). Radiographic outcomes were recorded in terms of coronal Cobb angle and lumbar lordosis. Results Mean patient age was 62.4 years, 50% of patients were female. Average follow up was 18.4 months. The average operative duration was 87.4 minutes, whilst the mean estimated blood loss was 45.6 ml. Mean coronal Cobb angle corrected from preoperative 15.2° to the final follow-up 6.8° (p < 0.05); and mean lumbar lordosis improved from preoperative 30.0° to 39.4° (p < 0.05). Mean disc height increased from preoperative 0.7 cm to 1.1 cm at final follow-up (p < 0.05). Mean VAS improved from 5.5 to 2.2 (p < 0.05). The mean preoperative and the final follow-up Oswestry Disability Indices were 27.8% and 13.1% respectively (p < 0.05). Conclusions Stand-alone OLIF could be regarded as an efficient and safe option in the treatment of ADS for careful selected patients.

OBJECTIVE There is no consensus regarding the best surgical strategy at the lumbosacral junction (LSJ) in long constructs for adult spinal deformity (ASD). The use of interbody fusion (IF) has been advocated to increase fusion rates, with additional pelvic fixation (PF) typically recommended. The actual benefit of IF even when extending to the pelvis, however, has not been vigorously analyzed. The goal of this work was to better understand the role of IF, specifically with respect to arthrodesis, when extending long constructs to the ilium. METHODS A systematic review of the PubMed and Cochrane databases was performed to identify the relevant studies in English, addressing the management of LSJ in long constructs (defined as ≥ 5 levels) in ASD. The search terms used were as follows: “Lumbosacral Junction,” “Long Constructs,” “Long Fusion to the Sacrum,” “Sacropelvic Fixation,” “Interbody Fusion,” and “Iliac Screw.” The authors excluded technical notes, case reports, literature reviews, and cadaveric studies; pediatric populations; pathologies different from ASD; studies not using conventional techniques; and studies focused only on alignment of different levels. RESULTS The PRISMA protocol was used. The authors found 12 retrospective clinical studies with a total of 1216 patients who were sorted into 3 different categories: group 1, using PF or not (n = 6); group 2, using PF with or without IF (n = 5); and group 3, from 1 study comparing anterior lumbar interbody fusion versus transforaminal lumbar interbody fusion. Five studies in group 1 and 4 in group 2 had pseudarthrosis rate as primary outcome and were selected for a quantitative analysis. Forest plots were used to display the risk ratio, and funnel plots were used to look at the risk of publication bias. The summary risk ratios were 0.36 (0.23–0.57, p < 0.001) and 1.03 (0.54–1.96, p = 0.94) for the PF and IF, respectively; there is a protective effect of overall pseudarthrosis for using PF in long constructs for ASD surgeries, but not for using IF. CONCLUSIONS The long-held contention that L5/S1 IF is always advantageous in long-construct deformity surgery is not supported by the current literature. Based on the findings from this systematic review and meta-analysis, PF with or without additional L5/S1 interbody grafting demonstrates similar overall construct pseudarthrosis rates. The added risk and costs associated with IF, therefore, should be more closely considered on a case-by-case basis.

BACKGROUND: Percutaneous endoscopic transforaminal lumbar interbody fusion (PE-TLIF) has been increasingly used to treat degenerative lumbar disease in recent years. However, there are still controversies about whether PE-TLIF is superior to minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). OBJECTIVES: To compare clinical outcomes and complications of PE-TLIF and MIS-TLIF in treating degenerative lumbar disease. STUDY DESIGN: A systematic review and meta-analysis. METHODS: A comprehensive search of online databases including PubMed, Embase, and the Cochrane Library was performed to identify related studies reporting the outcomes and complications of PE-TLIF and MIS-TLIF for degenerative lumbar disease. The clinical outcomes were assessed by the Visual Analog Scale and Oswestry Disability Index. In addition, the operative time, intraoperative blood loss, time to ambulation, length of hospital stay, fusion rate, and surgery-related complications were summarized. Forest plots were constructed to investigate the results. RESULTS: A total of 28 studies involving 1,475 patients were included in this meta-analysis. PE-TLIF significantly reduced operative time, intraoperative blood loss, time to ambulation, and length of hospital stay compared to MIS-TLIF. Moreover, PE-TLIF was superior to MIS-TLIF in the early postoperative relief of back pain. However, there were no significant differences in medium to long-term clinical outcomes, fusion rate, and incidence of complications between PE-TLIF and MIS-TLIF. LIMITATIONS: The current evidence is heterogeneous and most studies included in this meta-analysis are nonrandomized controlled trials. CONCLUSIONS: The present meta-analysis indicates that medium to long-term clinical outcomes and complication rates of PE-TLIF were similar to MIS-TLIF for the treatment of degenerative lumbar disease. However, PE-TLIF shows advantages in less surgical trauma, faster recovery, and early postoperative relief of back pain.

OBJECTIVEIn adult spinal deformity and degenerative conditions of the spine, interbody fusion to the sacrum often is performed to enhance arthrodesis, induce lordosis, and alleviate stenosis. Anterior lumbar interbody fusion (ALIF) has traditionally been performed, but minimally invasive oblique lumbar interbody fusion (OLIF) may or may not cause less morbidity because less retraction of the abdominal viscera is required. The authors evaluated whether there was a difference between the results of ALIF and OLIF in multilevel anterior or lateral interbody fusion to the sacrum.METHODSPatients from 2013 to 2018 who underwent multilevel ALIF or OLIF to the sacrum were retrospectively studied. Inclusion criteria were adult spinal deformity or degenerative pathology and multilevel ALIF or OLIF to the sacrum. Demographic, implant, perioperative, and radiographic variables were collected. Statistical calculations were performed for significant differences.RESULTSData from a total of 127 patients were analyzed (66 OLIF patients and 61 ALIF patients). The mean follow-up times were 27.21 (ALIF) and 24.11 (OLIF) months. The mean surgical time was 251.48 minutes for ALIF patients and 234.48 minutes for OLIF patients (p = 0.154). The mean hospital stay was 7.79 days for ALIF patients and 7.02 days for OLIF patients (p = 0.159). The mean time to being able to eat solid food was 4.03 days for ALIF patients and 1.30 days for OLIF patients (p < 0.001). After excluding patients who had undergone L5–S1 posterior column osteotomy, 54 ALIF patients and 41 OLIF patients were analyzed for L5–S1 radiographic changes. The mean cage height was 14.94 mm for ALIF patients and 13.56 mm for OLIF patients (p = 0.001), and the mean cage lordosis was 15.87° in the ALIF group and 16.81° in the OLIF group (p = 0.278). The mean increases in anterior disc height were 7.34 mm and 4.72 mm for the ALIF and OLIF groups, respectively (p = 0.001), and the mean increases in posterior disc height were 3.35 mm and 1.24 mm (p < 0.001), respectively. The mean change in L5–S1 lordosis was 4.33° for ALIF patients and 4.59° for OLIF patients (p = 0.829).CONCLUSIONSPatients who underwent multilevel OLIF and ALIF to the sacrum had comparable operative times. OLIF was associated with a quicker ileus recovery and less blood loss. At L5–S1, ALIF allowed larger cages to be placed, resulting in a greater disc height change, but there was no significant difference in L5–S1 segmental lordosis.

Abstract Background Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and oblique lateral interbody fusion (OLIF) are widely used in the treatment of lumbar degenerative diseases. In the present study, a meta-analysis was conducted to compare the clinical and radiographic efficacy of these two procedures. Methods A systematic literature review was performed, and the quality of retrieved studies was evaluated with the Newcastle-Ottawa Scale (NOS). Clinical outcomes, including operation time, intraoperative blood loss, improvement in Visual Analogue Scale (VAS), improvement in Oswestry Disability Index (ODI), Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) effectiveness rate and complications, in addition to radiographic outcomes, including restoration of disc height, disc angle, overall lumbar lordosis, fusion rate and subsidence, were extracted and input into a fixed or random effect model to compare the efficacy of MIS-TLIF and OLIF. Results Seven qualified studies were included. Clinically, OLIF resulted in less intraoperative blood loss and shorter operation time than MIS-TLIF. Improvement of VAS for leg pain was more obvious in the OLIF group (P < 0.0001), whereas improvement of VAS for back pain (P = 0.08) and ODI (P = 0.98) as well as JOABPEQ effectiveness rate (P = 0.18) were similar in the two groups. Radiographically, OLIF was more effective in restoring disc height (P = 0.01) and equivalent in improving the disc angle (P = 0.18) and lumbar lordosis (P = 0.48) compared with MIS-TLIF. The fusion rate (P = 0.11) was similar in both groups, while the subsidence was more severe in the MIS-TLIF group (P < 0.00001). Conclusions The above evidence suggests that OLIF is associated with a shorter operation time (with supplementary fixation in the prone position) and less intraoperative blood loss than MIS-TLIF and can lead to better leg pain alleviation, disc height restoration and subsidence resistance. No differences regarding back pain relief, functional recovery, complications, disc angle restoration, lumbar lordosis restoration and fusion rate were found. However, due to the limited number of studies, our results should be confirmed with high-level studies to fully compare the therapeutic efficacy of MIS-TLIF and OLIF.

Abstract Background The oblique lateral interbody fusion (OLIF) is a minimally invasive indirect decompression technique for the treatment of degenerative spinal disease. OLIF with posterior pedicle screws fixation frequently is performed, whereas it requires much more surgery time and blood loss. The purpose of this study was to compare the oblique lateral interbody fusion (OLIF) combined with lateral plate (LP) vs. OLIF combined with posterior pedicle screw (PS) fixation for the treatment of lumbar degenerative diseases.Methods The clinical data of 53 patients with lumbar degenerative diseases who underwent OLIF from January 2020 to September 2020 were retrospectively analyzed，24 in OLIF combined with lateral plate (OLIF+LP) group and 29 in OLIF combined with pedicle screw (OLIF+PS) group. All patients completed a minimum 1-year follow-up. The duration of operation, blood loss, fusion rate and complications were recorded. The visual analog scale (VAS) score, Oswestry Disability Index (ODI), disc height (DH), foraminal height (FH) and cross-sectional area (CSA) were also evaluated.Results The operation time was 75.41±11.53 min in the OLIF+LP group, which shorter than that in OLIF+PS group(127.05±5.62min, P<0.01). Also, the blood loss was significantly less in the OLIF+LP group (39.55±5.32 ml ) than in the OLIF+PS group (89.81±9.62, P<0.01). The VAS and ODI scores both significantly reduced after operation in OLIF+LP group. There was no difference either in VAS or ODI scores by 1 year after surgery between two groups (P>0.01). The DH, FH, and CSA parameters were all improved significantly after operation in both groups, however, there was no significant difference at the any follow-up point between the two groups. The total complication rate was 13.21% (7/53) in this study, and there was no siginificant difference between the two groups. The fusion rate was 91.67% in the OLIF+LP group and 93.10% in the OLIF+PS group (P =0.69).Conclusions OLIF+LP fixation seems to be a valuable surgical option for single-segmental lumbar degenerative disease, it can achieve much better clinical outcomes than OLIF+PS group.
