BACKGROUND
To compare the effectiveness and safety of anterior cervical discectomy and fusion (ACDF) with posterior cervical foraminotomy (PCF) for patients diagnosed with single-level unilateral cervical radiculopathy.
METHODS
Relevant studies comparing ACDF with PCF for cervical radiculopathy were searched in an electronic database. After data extraction and quality assessment of included studies, a meta-analysis was done by using the RevMan 5.3 software. The random effects model was used if there was heterogeneity between studies; otherwise, the fixed effects model was used.
RESULTS
A total of 3 randomized controlled trials (RCT) and 12 retrospective studies including 52705 patients were included in the meta-analysis. There were no significant differences in Neck Disability Index (NDI), Visual Analog Scale (VAS), and patients' satisfaction (P > 0.05) between treatment groups. The complication rate of the PCF group was equivalent compared with the ACDF group (P = 0.60), but the reoperation rate following PCF was on the higher side (P = 0.02). Data analysis also showed that the PCF group was associated with shorter operation time (P = 0.001) and shorter length of hospital stay (P = 0.002).
CONCLUSIONS
Among patients with single-level unilateral cervical radiculopathy, PCF has comparable effectiveness and complication rate compared with ACDF. It seems that PCF is a sufficient alternative procedure with shorter operation time, shorter length of hospital stay, and less total hospital cost for the treatment of cervical radiculopathy. However, the higher reoperation rate following PCF should be also taken into consideration.

Pathological changes in the ligamentum flavum (LF) can be defined as a process of chronic progressive aberrations in the nature and structure of ligamentous tissues characterized by increased thickness, reduced elasticity, local calcification, or aggravated ossification, which may cause severe myelopathy, radiculopathy, or both. Hypertrophy of ligamentum flavum (HLF) and ossification of ligamentum flavum (OLF) are clinically common entities. Though accumulated evidence has indicated both genetic and environmental factors could contribute to the initiation and progression of HLF/OLF, the definite pathogenesis remains fully unclear. MicroRNAs (miRNAs), one of the important epigenetic modifications, are short single-stranded RNA molecules that regulate protein-coding gene expression at posttranscriptional level, which can disclose the mechanism underlying diseases, identify valuable biomarkers, and explore potential therapeutic targets. Considering that miRNAs play a central role in regulating gene expression, we summarized current studies from the point of view of miRNA-related molecular regulation networks in HLF/OLF. Exploratory studies revealed a variety of miRNA expression profiles and identified a battery of upregulated and downregulated miRNAs in OLF/HLF patients through microarray datasets or transcriptome sequencing. Experimental studies validated the roles of specific miRNAs (e.g., miR-132-3p, miR-199b-5p in OLF, miR-155, and miR-21 in HLF) in regulating fibrosis or osteogenesis differentiation of LF cells and related target genes or molecular signaling pathways. Finally, we discussed the perspectives and challenges of miRNA-based molecular mechanism, diagnostic biomarkers, and therapeutic targets of HLF/OLF.

Meta-Analysis
BACKGROUND
Previous systemic reviews have examined the efficacy of individual therapeutic agents, but which type of treatment is superior to another has not been pooled or analyzed. The objective of the current study was to compare the clinical effectiveness of epidural steroid injection (ESI) versus conservative treatment for patients with lumbosacral radicular pain.
METHODS
A systematic search was conducted with MEDLINE, EMBASE, and CENTRAL databases with a double-extraction technique for relevant studies published between 2000 and January 10, 2019. The randomized controlled trials which directly compared the efficacy of ESI with conservative treatment in patients with lumbosacral radicular pain were included. Outcomes included visual analog scale, numeric rating scale, Oswetry disability index, or successful events. Two reviewers extracted data and evaluated the methodological quality of papers using the Cochrane Collaboration Handbook. A meta-analysis was performed using Revman 5.2 software. The heterogeneity of the meta-analysis was also assessed.
RESULTS
Of 1071 titles initially identified, 6 randomized controlled trials (249 patients with ESI and 241 patients with conservative treatment) were identified and included in this meta-analysis. The outcome of the pooled analysis showed that ESI was beneficial for pain relief at short-term and intermediate-term follow-up when compared with conservative treatment, but this effect was not maintained at long-term follow-up. Successful event rates were significantly higher in patients who received ESI than in patients who received conservative treatment. There were no statistically significant differences in functional improvement after ESI and conservative treatment at short-term and intermediate-term follow-up. The limitations of this meta-analysis resulted from the variation in types of interventions and small sample size.
CONCLUSIONS
According to the results of this meta-analysis, the use of ESI is more effective for alleviating lumbosacral radicular pain than conservative treatments in terms of short-term and intermediate-term. Patients also reported more successful outcomes after receiving ESI when compared to conservative treatment. However, this effect was not maintained at long-term follow-up. This meta-analysis will help guide clinicians in making decisions for the treatment of patients with lumbosacral radicular pain, including the use of ESI, particularly in the management of pain at short-term.

Comparative Study Meta-Analysis
Clinical Effectiveness of Interlaminar Epidural Injections of Local Anesthetic with or without Steroids for Managing Chronic Neck Pain: A Systematic Review and Meta-Analysis.
BACKGROUND
Chronic neck pain is reportedly considered the fourth leading cause of disability. Cervical interlaminar epidural injections are among the commonly administered nonsurgical interventions for managing chronic neck pain, secondary to disc herniation and radiculitis, spinal stenosis, or chronic neck pain of discogenic origin.
OBJECTIVES
To systematically review the differences in the effectiveness of cervical epidural injections with local anesthetics with or without steroids for the management of chronic neck pain.
STUDY DESIGN
Systematic review and meta-analysis.
METHODS
A comprehensive search of the literature of randomized controlled trials (RCTs) that compared epidural injections with local anesthetic with or without steroids was performed, including a search of PubMed, EMBASE, and Cochrane databases for all years up to May 2019. Meta-analysis was done for pain relief based on the Numeric Rating Scale, functional status based on the Neck Disability Index, and opioid intake dosage.
RESULTS
Four studies met the inclusion criteria. A total of 370 patients were divided into 2 groups: the experimental group received cervical epidural injection with steroid and local anesthetic, and the control group received injection with local anesthetic only. Regrading pain relief, no significant difference was observed between both groups (weighted mean difference [WMD], -0.006; 95% confidence interval (CI), -0.275 to 0.263; P = 0.963; I² = 0.0% at 12 months). There was also no significant difference in the improvement of the functional status (WMD, 0.159; 95% CI, -1.231 to 1.549; P = 0.823; I² = 9.8% at 12 months). Similarly, there was no significant difference in opioid dosage (WMD, -0.093; 95% CI, -5.952 to 5.766; P = 0.975; I² = 0.0% at 12 months).
LIMITATIONS
Only a few studies on this premise were found in the literature. There was also a lack of heterogeneity of the included RCT studies.
CONCLUSIONS
The addition of steroids to anesthetic injectates was not associated with better pain and functional score outcomes compared with anesthetic injectate alone in patients with chronic neck pain.

BACKGROUND
Spinal cord tumors present a challenge in diagnosis and treatment due to their varied histopathological characteristics. While Ewing sarcoma is a rare malignant tumor typically originating from skeletal bone, cases of primary intradural extraskeletal Ewing sarcoma are exceptionally rare. The similarity of its presentation to other spinal tumors further complicates its identification and management.
CASE PRESENTATION
We report a case of a 58-year-old Palestinian male with intradural extraskeletal lumbar Ewing sarcoma. The patient initially presented with lower back pain and bilateral S1 radiculopathy, with more severe symptoms on the left side. Magnetic resonance imaging revealed a 7 cm oval-shaped mass with homogeneous contrast enhancement, obstructing the spinal canal from L3/L4 to L5/S1 levels. Initially, a myxopapillary ependymoma was suspected, but the patient's sensory and motor functions suddenly deteriorated during hospitalization. Repeat magnetic resonance imaging indicated heterogeneous contrast enhancement, indicating acute intratumoral hemorrhage. Consequently, the patient underwent emergent L3-L5 laminotomy, with successful gross total resection of the tumor. Histopathological and immunohistochemical analyses confirmed the diagnosis of intradural extraskeletal Ewing sarcoma. Adjuvant therapy was administered to minimize the risk of local recurrence or distant metastasis. A systematic review of relevant literature, along with retrospective analysis of medical records, operative reports, radiological studies, and histopathological findings of similar cases, was also conducted.
CONCLUSIONS
Intradural extraskeletal Ewing sarcoma is an infrequently encountered condition in adult patients, emphasizing the importance of considering it in the differential diagnosis of spinal tumors. Surgeons must possess a comprehensive understanding of this rare entity to ensure accurate staging and optimal management, particularly in the early stages when prompt intervention may improve prognosis.
