A Comprehensive Analysis of Potential Complications after Oblique Lumbar Interbody Fusion : A Review of Postoperative Magnetic Resonance Scans in Over 400 Cases.

ABSTRACT:

Objective

This study focuses on identifying potential complications following oblique lumbar interbody fusion (OLIF) through routine magnetic resonance (MR) scans.

Methods

From 650 patients who underwent OLIF from April 2018 to April 2022, this study included those with MR scans taken 1-week post-operatively, and only for indirect decompression patients. The analysis evaluated postoperative MR images for hematoma, cage insertion angles, and indirect decompression efficiency. Patient demographics, post-operatively symptoms, and complications were also evaluated.

Results

Out of 401 patients enrolled, most underwent 1- or 2-level OLIF. Common findings included approach site hematoma (65.3%) and contralateral psoas hematoma (19%). The caudal level OLIF was related with less orthogonality and deep insertion of cage. Incomplete indirect decompression occurred in 4.66% of cases but did not require additional surgery. Rare but symptomatic complications included remnant disc rupture (four cases, 1%) and synovial cyst rupture (four cases, 1%).

Conclusion

This study has identified potential complications associated with OLIF, including approach site hematoma, contralateral psoas hematoma, cage malposition risk at caudal levels, and radiologically insufficient indirect decompression. Additionally, it highlights rare, yet symptomatic complications such as remnant disc rupture and synovial cyst rupture. These findings contribute insights into the relatively under-explored area of OLIF complications.

Project description:BackgroundOblique lumbar interbody fusion (OLIF) is a minimally invasive technique performed through the antero-oblique trajectory to address a wide range of lumbar pathologies. However, it can lead to complications. We reviewed the results of OLIF and discussed the effective methods to avoid such complications.MethodsSeventy-nine consecutive patients who underwent OLIF between May 2016 and July 2019 were retrospectively analyzed. They were divided into three groups: stand-alone, posterior, and lateral fixation, according to whether they were followed up with auxiliary internal fixation as well as the fixation methods. Preoperative and last follow-up visual analog scale (VAS) and Oswestry Disability Index (ODI) scores were used to assess the improvement in the lower back and leg pain as well as neurological conditions. We analyzed intervertebral disc height (DH), segmental lumbar lordotic angle (SLL), lumbar lordotic angle (LL), pelvic tilt (PT), pelvic incidence-lumbar lordosis (PI-LL) mismatch, and the cross-section area (CSA) on axial magnetic resonance imaging (MRI) image in different groups. Complications, including thigh symptoms, cage subsidence, neurological injury, and vascular injury, were also noted.ResultsSeventy-nine patients were followed up postoperatively for 23.2±11.5 (range, 12-48) months. Forty-eight (61%) patients underwent stand-alone surgery (without fixation), 15 (19%) patients underwent supplemental percutaneous pedicle screw fixation (posterior fixation), and 16 (20%) patients underwent lateral vertebral instrumentation (lateral fixation). In all three groups, the VAS score and the ODI score had significantly decreased at the final follow-up compared to pre-operation. The DH, SLL, LL, CSA, PT, and PI-LL mismatch had also improved by final follow-up. The most common approach-related complication was thigh symptoms. Of the 79 patients, ipsilateral transient psoas paresis occurred in 9 (11.4%), ipsilateral transient quadriceps weakness in 2 (2.5%), and groin/thigh numbness and pain in 17 (21.5%). Cage subsidence occurred in 8 (10.1%) patients, including five cases of grade 0, one of grade I, and two of grade II. Three (3.8%) patients in this study had a vascular injury.ConclusionsOLIF is a minimally invasive and effective technique for dealing with degenerative lumbar diseases. However, it should also be noted that this approach carries risks of complications.

Project description:ObjectiveThis study aims to perform a meta-analysis that integrates multiple literature sources to evaluate the clinical efficacy of oblique lumbar interbody fusion (OLIF) versus minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for treating lumbar degenerative diseases (LDD).MethodsA systematic search was conducted across various databases, including CNKI, VIP, WANFANG DATA, SinoMed, PubMed, Cochrane Library, Embase, and Web of Science, for clinical comparative studies on OLIF and MIS-TLIF for treating LDD, covering the time frame from the inception of the databases to September 2024. Following PRISMA guidelines, studies were screened, assessed, and data were extracted rigorously. Indicators extracted included operative time, intraoperative blood loss, hospital stay, visual analog scale (VAS) scores, Oswestry Disability Index (ODI), disc height (DH), segmental lordotic angle (SLA), lumbar lordosis angle (LLA), postoperative JOA scores, patient satisfaction, complication rates, and fusion rates. Meta-analysis was performed using Review Manager 5.4 software.ResultsA total of 24 studies were included, comprising 11 randomized controlled trials and 13 retrospective cohort studies. The total population consisted of 1785 patients, with 898 in the OLIF group and 887 in the MIS-TLIF group. The meta-analysis indicated that, compared to the MIS-TLIF group, the OLIF group exhibited significantly lower intraoperative blood loss, shorter hospital stays, improved postoperative DH, shorter operative time, reduced postoperative VAS scores, lower postoperative ODI scores, and improved postoperative SLA and LLA. No significant differences were observed between the groups in postoperative JOA scores, fusion rates, complication rates, or patient satisfaction. The OLIF group exhibited advantages such as lower blood loss, shorter hospital stays, higher postoperative fusion rates, and improved recovery of disc and foraminal heights.ConclusionCompared to MIS-TLIF, OLIF is associated with a shorter operative time and less intraoperative blood loss, potentially leading to better relief of leg pain, restoration of DH, and prevention of subsidence. These findings offer valuable insights for clinical practice.

Project description:BackgroundMinimally 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.MethodsA 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.ResultsSeven 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).ConclusionsThe 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.Trial registrationPROSPERO ID: CRD42020201903 .
