Radiological Assessment of Postoperative Paraspinal Muscle Changes After Lumbar Interbody Fusion With or Without Minimally Invasive Techniques.

ABSTRACT:

Study design

Retrospective cohort study.

Background

Percutaneous pedicle screws (PPS) have the advantage of being able to better preserve the paraspinal muscles when compared with a traditional open approach. However, the nature of changes in postoperative paraspinal muscle after damage by lumbar fusion surgery has remained largely unknown. It is clinically important to clarify and compare changes in paraspinal muscles after the various surgeries.

Objective

(1) To determine postoperative changes of muscle density and cross-sectional area using computed tomography (CT), and (2) to compare paraspinal muscle changes after posterior lumbar interbody fusion (PLIF) with traditional open approaches and minimally invasive lateral lumbar interbody fusions (LLIF) with PPS.

Methods

We included data from 39 consecutive female patients who underwent open PLIF and 23 consecutive patients who underwent single-staged treatment with LLIF followed by posterior PPS fixation at a single level (L4-5). All patients underwent preoperative, 6 months postoperative, and 1-year postoperative CT imaging. Measurements of the cross-sectional area (CSA) and muscle densities of paraspinal muscles were obtained using regions of interest defined by manual tracing.

Results

We did not find any decrease of CSA in any paraspinal muscles. We did find a decrease of muscle density in the multifidus at 1 year after surgery in patients in the PILF group, but not in those in LLIF/PPS group.

Conclusions

One year after surgery, a significant postoperative decrease of muscle density of the multifidi was observed only in patients who underwent open PLIF, but not in those who underwent LLIF/PPS.

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 .

Project description:BackgroundThe previous studies agree that minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) has better function outcomes, less blood loss, and shorter hospital stay, when compared to open-TLIF. However, there are no significance differences on operative time, complication, and reoperation rate between the two procedures. This could be from less relative literatures and lower grade evidence. The further meta-analysis is needed with more and higher grade evidences to compare the above two TLIF procedures.MethodsProspective and retrospective studies that compared open-TLIF and MIS-TLIF were identified by searching the Medline, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP database (the literature search comprised Medical Subject Heading terms and key words or Emtree term). The retrieval time ranged from the date when the database was founded to January 2015. Pooled risk ratios (RR s) and weighted mean differences (WMDs) with 95% confidence intervals were calculated for the clinical outcomes and perioperative data.ResultsTwenty-four studies (n = 1967 patients) were included in this review (n = 951, open-TLIF, n = 1016, MIS-TLIF). MIS-TLIF was associated with a significant decrease in the visual analog score (VAS)-back pain score (WMD = -0.44; P = 0.001), Oswestry Disabilities Index (WMD = -1.57; P = 0.005), early ambulation (WMD = -1.77; P = 0.0001), less blood loss (WMD = -265.59; P < 0.00001), and a shorter hospital stay (WMD = -1.89; P < 0.0001). However, there were no significant differences in the fusion rate (RR = 0.99; P = 0.34), VAS-leg pain (WMD = -0.10; P = 0.26), complication rate (RR = 0.84; P = 0.35), operation time (WMD = -5.23; P = 0.82), or reoperation rate (RR = 0.73; P = 0.32).ConclusionsMIS-TLIF resulted in a similar fusion rate with better functional outcome, less blood loss, shorter ambulation, and hospital stay; furthermore, it did not increase the complication or reoperation rate based on the existing evidence.
