Abstract
Background: Meralgia paresthetica (MP), a common entrapment syndrome, presents with paresthesias in the anterolateral aspect of the thigh. Clinical tests used to diagnose MP are the pelvic compression test, neurodynamic testing, and Tinel's sign. The diagnostic accuracy of these three tests has not been analyzed to date. Hence, this study aims to analyze the sensitivity and specificity of these clinical tests. Case Study: This study was a hospital-based case-control study that included 30 electrophysiologically proven patients with MP. The data were gathered over a period of 6 months after obtaining institutional ethics committee clearance. Demographics and risk factors among our cases are in keeping with the global scenario. The sensitivity and specificity of the pelvic compression test were 86.7% and 93.0%, the Tinsel sign was 85.1% and 87.5%, and neurodynamic testing was 86.7% and 93.0%, respectively. Conclusion: Our study proves that these tests are a simple and accurate aid in the diagnosis of MP. These bedside clinical tests can be utilized to establish a diagnosis of MP in a setting of conflicting differentials such as lumbar canal stenosis or thoracolumbar junction disc pathologies and guide in choosing the next line of investigation.

Natural Language Processing-Driven Artificial Intelligence Models for the Diagnosis of Lumbar Disc Herniation with L5 and S1 Radiculopathy: A Preliminary Evaluation. World Neurosurg 2024; 189:e300-e309. [PMID: 38878892 DOI: 10.1016/j.wneu.2024.06.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2024] [Accepted: 06/09/2024] [Indexed: 07/07/2024]
Abstract
OBJECTIVE To develop and validate natural language processing-driven artificial intelligence (AI) models for the diagnosis of lumbar disc herniation (LDH) with L5 and S1 radiculopathy using electronic health records (EHRs). METHODS EHRs of patients undergoing single-level percutaneous endoscopic lumbar discectomy for the treatment of LDH at the L4/5 or L5/S1 level between June 1, 2013, and December 31, 2021, were collected. The primary outcome was LDH with L5 and S1 radiculopathy, which was defined as nerve root compression recorded in the operative notes. Datasets were created using the history of present illness text and positive symptom text with radiculopathy (L5 or S1), respectively. The datasets were randomly split into a training set and a testing set in a 7:3 ratio. Two machine learning models, the long short-term memory network and Extreme Gradient Boosting, were developed using the training set. Performance evaluation of the models on the testing set was done using measures such as the receiver operating characteristic curve, area under the curve, accuracy, recall, F1-score, and precision. RESULTS The study included a total of 1681 patients, with 590 patients having L5 radiculopathy and 1091 patients having S1 radiculopathy. Among the 4 models developed, the long short-term memory model based on positive symptom text showed the best discrimination in the testing set, with precision (0.9054), recall (0.9405), accuracy (0.8950), F1-score (0.9226), and area under the curve (0.9485). CONCLUSIONS This study provides preliminary validation of the concept that natural language processing-driven AI models can be used for the diagnosis of lumbar disease using EHRs. This study could pave the way for future research that may develop more comprehensive and clinically impactful AI-driven diagnostic systems.

[PMID: 38815923 DOI: 10.1016/j.wneu.2024.05.149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Accepted: 05/22/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND Various methods and techniques have been developed for extraforaminal decompression, particularly for far lateral lumbar disc herniation. Distinct anatomical differences are noticeable in the upper levels of the lumbar spine, which may complicate the related surgical approach. This study aimed to determine the safety and efficiency of the far lateral extraforaminal approach for the upper lumbar disc. METHODS L1-2 and L2-3 migrated lumbar disc herniations were defined as upper lumbar disc herniations. 31 consecutive patients with upper lumbar disk herniation who underwent extraforaminal lumbar microdiscectomy between January 2018 and March 2022 were retrospectively investigated. The patients were assessed using the interval history, follow-up lower back and leg pain visual analog scale scores (0-100 mm), the Oswestry Disability Index (%), and modified MacNab criteria. RESULTS 31 consecutive patients with upper lumbar disk herniation (20 men and 11 women) with a mean age of 52.8 ± 10.8 years (range 31-70 years) underwent extraforaminal lumbar microdiscectomy. The preoperative and postoperative visual analog scale scores and Oswestry Disability Index were significantly different (P < 0.001). According to the modified MacNab criteria, 23 patients showed excellent improvement, 5 showed good improvement, and 3 showed fair improvement; thus, the rate of satisfactory improvement was 90.3% at the 2-year follow-up. No patients required reoperation at the operative level during follow-up. CONCLUSIONS Extraforaminal lumbar microdiscectomy is a safe and effective minimally invasive surgical technique for treating upper lumbar disc herniation.

Abstract
BACKGROUND Upper lumbar disc herniation (ULDH) accounts for 1-10% of all lumbar disc herniations (LDH). This study aimed to evaluate the clinical characteristics and outcomes of patients with ULDH who underwent percutaneous transforaminal endoscopic discectomy (PTED) compared with those with lower LDH. METHODS 60 patients with ULDH or L4-L5 LDH treated with PTED between May 2016 and October 2021. MacNab criteria, visual analog scale (VAS) of back pain and leg pain, and Japanese Orthopedic Association (JOA) were evaluated before and after surgery. RESULTS In the L1-L3 group, 59.1% of the patients had a positive femoral nerve tension test, and 81.8% of the patients had a sensory deficit. Both groups showed significant improvements in VAS scores for low back and leg pain, and JOA scores postoperatively. No significant differences in the degree of improvement were observed between the two groups. The excellent/good rate was 81.8% in the L1-L3 group and 84.2% in the L4-L5 group, showing no significant difference. CONCLUSION PTED has comparable efficacy in treating ULDH as it does in treating lower LDH, it is a safe and effective treatment method for ULDH.

Abstract
BACKGROUND Thoracolumbar disc herniation (TLDH) is a rare disorder with unique characteristics that can result in undesirable surgical outcomes after traditional discectomy. In view of the widespread use of transforaminal endoscopic discectomy for lower lumbar disc herniation, we investigated treatment of TLDH by this procedure. The purpose of this study was to evaluate the clinical efficacy of transforaminal endoscopic discectomy for treating TLDH and share our technical experience. METHODS We retrospectively evaluated the clinical data of 19 patients who had undergone transforaminal endoscopic discectomy for TLDH in our institution between April 2018 and July 2021. Operation time, follow-up time, blood loss, postoperative hospital stay, visual analog scale scores for low-back and leg pain, and Japanese Orthopedic Association (JOA) scores were evaluated. RESULTS The differences between preoperative and postoperative JOA and visual analog scale scores were significant (P < 0.05). According to the JOA scores, 14 of the 19 patients had excellent improvement, 3 had good improvement, and 2 had fair improvement; thus, the rate of satisfactory improvement was 89.5%. CONCLUSIONS Operation time, blood loss, postoperative hospital stay, and surgical outcomes were favorable. Transforaminal endoscopic discectomy is an ideal surgical procedure for treating TLDH.

Abstract
To analyze the clinical characteristics and surgical outcomes of TLDH with Autologous Bone-Fusion for T10-L1 TLDH or Cage-Fusion for T12-L3 TLDH. This is a retrospective multi-center clinical study, involving a total of 43 patients with TLDH who underwent surgery in our institutions from December 2013 to January 2021. In all, 15 of 43 patients (34.9%) with T10-11(2)/T11-12(5)/T12-L1 (8) TLDH underwent Autologous Bone-Fusion surgery and 28 of 43 patients (65.1%) with T12-L1(3)/L1-L2(12)/L2-L3(13) TLDH underwent Cage-Fusion surgery. Demographic data, clinical characteristics and perioperative outcomes were recorded. During the follow-up, pre- to post-operative ODI, VAS back and leg pain scores significantly decreased (P1.2 = 0.001) and the score changes had no significant difference between two groups (P3 = 0.81, 0.59, 0.68). The intraoperative blood loss and operation time showed no significant difference between two groups (P = 0.056, 0.072). The patients showed prominent improvement of hypokinesia and satisfactory rate in two groups (5/7, 71.4% VS 9/12, 75.0%, P = 0.633; 11, 73.3% VS 25, 89.3%, P = 0.281). Notably, no recurrence and severe complications were reported. The choice of surgery approach should be individualized by clinical characteristics and radiology. Selectively Autologous Bone-Fusion for T10-L1 TLDH or Cage-Fusion for T12-L3 TLDH provided adequate nerve decompression and immediate stability. The overall fusion surgical outcomes were satisfactory without major complications during follow-up.

Abstract
Degenerative disc disease (DDD), a major contributor to discogenic pain, which is mainly resulted from the dysfunction of nucleus pulposus (NP), annulus fibrosis (AF) and cartilage endplate (CEP) cells. Genetic and cellular components alterations in CEP may influence disc homeostasis, while few single-cell RNA sequencing (scRNA-seq) report in CEP makes it a challenge to evaluate cellular heterogeneity in CEP. Here, this study conducted a first conjoint analysis of weighted gene co-expression network analysis (WGCNA) and scRNA-seq in CEP, systematically analyzed the interested module, immune infiltration situation, and cell niches in CEP. WGCNA and protein-protein interaction (PPI) network determined a group of gene signatures responsible for degenerative CEP, including BRD4, RAF1, ANGPT1, CHD7 and NOP56; differentially immune analysis elucidated that CD4+ T cells, NK cells and dendritic cells were highly activated in degenerative CEP; then single-cell resolution transcriptomic landscape further identified several mesenchymal stem cells and other cellular components focused on human CEP, which illuminated niche atlas of different cell subpopulations: 8 populations were identified by distinct molecular signatures. Among which, NP progenitor/mesenchymal stem cells (NPMSC), also served as multipotent stem cells in CEP, exhibited regenerative and therapeutic potentials in promoting bone repair and maintaining bone homeostasis through SPP1, NRP1-related cascade reactions; regulatory and effector mesenchymal chondrocytes could be further classified into 2 different subtypes, and each subtype behaved potential opposite effects in maintaining cartilage homeostasis; next, the potential functional differences of each mesenchymal stem cell populations and the possible interactions with different cell types analysis revealed that JAG1, SPP1, MIF and PDGF etc. generated by different cells could regulate the CEP homeostasis by bone formation or angiogenesis, which could be served as novel therapeutic targets for degenerative CEP. In brief, this study mainly revealed the mesenchymal stem cells populations complexity and phenotypic characteristics in CEP. In brief, this study filled the gap in the knowledge of CEP components, further enhanced researchers’ understanding of CEP and their cell niches constitution.

Abstract
Intervertebral disc degeneration (IDD) results from the dysfunction of nucleus pulposus (NP) cells and the exhaustion of NP progenitors (ProNPs). The cellular applications of NP cells during IDD are currently limited due to the lack of in vivo studies showing whether NP cells are heterogeneous and contain ProNPs throughout postnatal stages. In this study, single-cell RNA sequencing of purified NP cells is used to map four molecularly defined populations and urotensin II receptor (UTS2R)-expressing postnatal ProNPs is identified, which are markedly exhausted during IDD, in mouse and human specimens. The lineage tracing shows that UTS2R+ ProNPs preferentially resides in the NP periphery with its niche factor tenascin-C and give rise to functional NP cells. It is also demonstrated that transplanting UTS2R+ ProNPs with tenascin-C into injured intervertebral discs attenuate the progression of IDD. The study provides a novel NP cell atlas, identified resident ProNPs with regenerative potential, and revealed promising diagnostic and therapeutic targets for IDD.

Abstract
BACKGROUND Microendoscopic discectomy (MED) and percutaneous transforaminal endoscopic discectomy (PTED), as two alternative surgical techniques in minimally invasive spine surgery (MISS), are widely conducted in the treatment of upper lumbar disc herniation (ULDH). This study will systematically assess and compare the clinical outcomes of MED and PTED in treating ULDH combining with the meta-analysis. METHODS All the randomized controlled trials (RCTs) will be searched at the databases including PubMed, EMBASE, Cochrane Library and Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Chinese Scientific Journal Database (VIP), and WANFANG Database from inception to December 2025. The primary outcome will involve Japanese Orthopedic Association (JOA), Oswestry disability index (ODI), and visual analog scale (VAS) scores. The secondary outcomes will be the short-form 36-item (SF-36) health survey questionnaire and the modified MacNab criterion. We will perform data synthesis, subgroup analysis, sensitivity analysis, meta-regression analysis, and the assessment of reporting bias using RevMan 5.3 software. RESULTS This systematic review will comprehensively evaluate the clinical outcomes of comparison of MED and PTED in the treatment of ULDH and provide a reliable and high-quality evidence. CONCLUSION The conclusion of this study will elucidate the clinical outcomes of MED compared with PTED and clarify whether PTED generates better clinical effects than MED in treating ULDH.

Abstract
Intervertebral disc degeneration (IVDD) is considered to be the fundamental cause of the occurrence and development of lumbar disc herniation (LDH). The degeneration of IVDD is mainly caused by the participation of inflammatory factors. Thus, it is of great significance to analyze the pathogenesis of IVDD, which may guide clinical prevention and treatment of LDH. Our current study aims to identify the role of miR-495-3p in LDH and to further unravel the underlying mechanisms. Results in the current study showed that TNF-α treatment markedly inhibited cell viability of HNPC, increased the IL-1β level, and decreased the mRNA level of miR-495-3p in HNPC in a time-dependent manner. Up-regulation of miR-495-3p promoted cell proliferation and inhibited inflammation and apoptosis in TNF-α-induced HNPCs. To investigate the underlying molecular mechanism through which miR-495-3p regulates TNF-α-induced inflammation and apoptosis in HNPCs, we explored the possible target gene of miR-495-3p. Bioinformatics analysis indicated that IL5RA, which is an important gene for TNF-α-induced HNPC injury, was also a target gene of miR-495-3p. A luciferase reporter assay was applied to test and verify the direct target association between miR-495-3p and IL5RA. The results discovered that down-regulation of miR-495-3p markedly reversed the anti-apoptosis and anti-inflammation of sh-IL5RA. In short, the present study evaluated the roles of miR-495-3p and IL5RA in IVDD development and progression. All the data indicated that miRNA-495-3p may play a protective role via inhibiting inflammation and apoptosis in human nucleus pulposus cells by targeting IL5RA pathway. Therefore, miRNA-495-3p may be a potential agent for LDH, and our study may provide a novel strategy in LDH treatment.

Abstract
Aim The aim of this study is to apply surgical treatments to upper lumbar disc hernias in order to provide lumbar stability and lumbar lordosis using a transforaminal lumbar interbody fusion (TLIF) cage and to preserve the success rate of surgical results by protecting neural structures without excessive subject tension. Material and methods Between 2012 and 2017, 32 patients who had undergone an operation for upper lumbar disc herniation and who had received a transforaminal lumbar interbody fusion cage using a posterior technique were evaluated retrospectively. Results The radiological and clinical findings, surgical methods, and results of the patients were evaluated. In our study, 25 (78.1%) of the patients with upper lumbar disc hernias who were evaluated retrospectively were female and seven (21.9%) were male. Their average age was 55.43 years. The average follow-up was 21.75 months. The most common complaints were lower back pain, leg pain, and claudication. In the findings from neurological examinations, a positive result on the femoral stretching test occurred in 30 (93.7%) patients. In the degenerative spinal structure of patients at the L1-2 and L2-3 levels, a transforaminal lumbar interbody fusion was performed via a wide laminectomy with posterior stabilization due to a wide-bottomed disc hernia and stenosis. Only one of the patients with a neurological deficit still had a motor deficit after surgery. Conclusion While planning a surgery for upper lumbar disc hernias, the anatomical features of this region and the patients' radiological and neurological findings should be carefully evaluated. If TLIF is performed during upper lumbar region surgery, it may be preferable to perform it using a posterior technique.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To conduct a literature review on outcomes of discectomy for upper lumbar disc herniations (ULDH), estimate pooled rates of satisfactory outcomes, compare open laminectomy/microdiscectomy (OLM) versus minimally invasive surgical (MIS) techniques, and compare results of disc herniations at L1-3 versus L3-4. METHODS A systematic review of articles reporting outcomes of nonfusion surgical treatment of L1-2, L2-3, and/or L3-4 disc herniations was performed. The inclusion and exclusion of studies was performed according to the latest version of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS A total of 20 articles were included in the quantitative meta-analysis. Pooled proportion of satisfactory outcome (95% CI) was 0.77 (0.70, 0.83) for MIS and 0.82 (0.78, 0.84) for OLM. There was no significant improvement with MIS techniques compared with standard OLM, odds ratio (OR) = 0.86, 95% CI (0.42, 1.74), P = .66. Separating results by levels revealed a trend of higher satisfaction with L3-4 versus L1-3 with OLM surgery, OR = 0.46, 95% CI (0.19, 1.12), P = .08. CONCLUSION Our analysis reveals that discectomy for ULDH has an overall success rate of approximately 80% and has not improved with MIS. Discectomy for herniations at L3-4 trends toward better outcomes compared with L1-2 and L2-3, but was not significant.

Abstract
Background
Surgical outcomes of upper lumbar disc herniations (ULDHs) including T12-L1, L1-L2, and L2-L3 levels are characteristically less favorable and more unpredictable.
Objectives
This study was conducted to compare the surgical outcomes of decompression alone versus decompression combined with transpedicular screw fixation in treating upper lumbar disc herniation.
Methods
This retrospective cohort study was carried out at Neurosurgery Departments, Tanta University. The study included 46 patients with a symptomatic high lumbar herniated disc at T12-L1, L1-L2, and L2-L3 levels. The enrolled patients were divided into two groups depending on whether they were operated on via decompression and partial medial facetectomy (group 1, 22 patients) or via the previous maneuver plus transpedicular screw fixation (group 2, 24 patients). All patients were medically evaluated immediately after the operation; then, they were followed up at the 3rd and the 6th months following surgery. Patients’ outcomes were assessed by visual analogue score (VAS) and Oswestry Disability Index (ODI) scores.
Results
Median VAS scores in each group revealed significant reduction immediately following surgery and at each of 7 days, 3 months, and 6 months in comparison with the preoperative VAS score (p<0.001). Furthermore, each group showed significant stepwise reduction in the median ODI score at the 3rd and the 6th months postoperative compared to the preoperative ODI score (group 1 = 68.0, 19.0, 15.0; p< 0.001 and group 2 = 66.5, 20.0, 15.0; p< 0.001), with no significant differences between both groups (p> 0.05).
Conclusions
Both standalone decompression and decompression combined with transpedicular screw fixation revealed comparable favorable outcomes in patients with ULDH.

Abstract
(1) Introduction: Epiconus and conus medullary syndromes that consisted of drop foot, pain, numbness, bladder or bowel dysfunction are serious problems might be caused by lumbar disc(s) herniation (LDH) compression. (2) Objective: To evaluate percutaneous discectomy effectivity for decompressing LDH lesions. (3) Case Report: Three patients suffered from drop feet, numbness, and bowel and bladder problems due to LDH compression. Patient #1 is a male (35 years old, basal metabolism index (BMI) = 23.9), point 1 on manual muscle test (MMT), with protrusion on L3 to S1 discs; Patient #2 is a female (62 years old, BMI = 22.4), point 3 on MMT, with protrusion on L2-4 and L5-S1 discs; Patient #3 is a female (43 years old, BMI = 26.6), point 4 on MMT, with extrusion on T12-L1 and L1-2 and L3-4 protruded discs. Six months follow-up showed of stand and walkability improvement with Patient #1 and #2. Patient #3 showed improvement in bowel and bladder problems within 10 weeks, without suffering of postoperative pain syndromes. (4) Discussion: Patient #1 and #2 showed better outcomes than Patient #3 who affected epiconus and cauda equina syndromes. Triamcinolone and lidocaine have analgesic and anti-inflammatory properties for improving intraepidural circulation adjacent to the lesion sites. (5) Conclusion: Drop foot caused by mechanical compression of LDH ought to be treated immediately. Lateral or posterolateral compression has better outcomes associated with anatomical structures. Discectomy through transforaminal approach that is followed by caudal epidural steroid injection (CESI) under fluoroscopic guidance is a safer and minimally invasive treatment with promising outcomes.

Abstract
BACKGROUND Disc herniation is a condition where tearing occurs in the outer annular layer of the intervertebral pad leading the inner gel-like material to bulge ouwards the spinal cord, due to the high load of the vertebrae. This will produce back pain and symptoms in different sites according to the level of the herniation in the vertebral column. AIM To compare the level of awareness regarding disc herniation among the general population and medical students in Jeddah. METHODOLOGY A descriptive cross-sectional study was conducted through an electronic questionnaire to assess the level of awareness regarding disc prolapse among the general population and medical students in Jeddah. The questionnaire was in the Arabic language, it was taken and validated by the previous study which took place in Taif. RESULTS Our studied sample involved 1026 individuals aged between 11 and 99 years, with a mean age of 34.03 ± 13.28 years old. More than half of the respondents were female (55.4%), most of them were Saudi nationals (90.1%), and most of them have received a higher education (67.7%). Results showed that 54.1% of the general population and 77.7% of medical students reported good knowledge regarding this condition. CONCLUSION This study revealed that the level of awareness regarding disc prolapse among the general population and medical students was poor in some respects such as: knowledge about the preventive measures, symptoms of the disease, the most common site in the spine affected by the disease, and the gold standard imaging method to diagnose this disease.

Abstract
Background Percutaneous endoscopic transforaminal discectomy (PETD) is regarded as a viable alternative option for upper lumbar disc herniation (LDH). However, few studies have evaluated PETD for upper LDH, and no study has compared the advantages of endoscopic procedures versus conventional surgery. The present study was aimed at comparing the surgical outcome and safety of PETD versus conventional open lumbar discectomy in the treatment of upper LDH. Methods Data from 42 patients treated for upper LDH from July 2015 to July 2018 were retrospectively analyzed, including 21 patients treated with PETD (PETD group) and 21 patients treated with conventional posterior lumbar discectomy (open group). The two groups were compared regarding demographic information, physical examination, radiological evaluations, and perioperative indicators. The clinical outcomes were assessed in accordance with the Oswestry Disability Index (ODI), visual analog scale (VAS), and modified MacNab criteria. Results The postoperative ODI and VAS scores were significantly improved in both groups compared with the preoperative baseline values (P < 0.001), and the satisfactory rate was 90.5% in both groups in accordance with the modified MacNab criteria. There were no significant differences between the two groups in the clinical outcomes and complication rate (P < 0.001), and the satisfactory rate was 90.5% in both groups in accordance with the modified MacNab criteria. There were no significant differences between the two groups in the clinical outcomes and complication rate (P < 0.001), and the satisfactory rate was 90.5% in both groups in accordance with the modified MacNab criteria. There were no significant differences between the two groups in the clinical outcomes and complication rate ( Conclusions PETD has a similar outcome to the conventional surgical method for the treatment of upper LDH but provides the typical advantages of minimally invasive procedures such as reduced iatrogenic injury, minimal activity restrictions, and accelerated ambulation recovery postoperatively.

Abstract
Upper lumbar herniated intervertebral disc (HIVD), defined as L1-2 and L2-3 levels, presents with a lower incidence and more unfavorable surgical outcomes than lower lumbar levels. There are very few reports onthe appropriate surgical interventions for treating upper lumbar HIVD. This study aimed to evaluate the surgical outcome of decompression alone, when compared with spinal fusion surgery. A retrospective study involving a total of 7592 patients who underwent surgery due to HIVD in our institution was conducted. A total of 49 patients were included in this study: 33 patients who underwent decompression-only surgery and 16 patients who underwent fusion surgery. Demographic data, perioperative information, and functional outcomes were recorded. The visual analog scale (VAS) scores showed improvement in both groups postoperatively. The three-month postoperative Oswestry Disability Index score was significantly better in the fusion group. Additionally, 10 patients (76.9%) in the decompression group and 5 patients (83.3%) in the fusion group reported improvement in preoperative motor weakness. The final “satisfactory” rate was 66.7% in the decompression group and 93.8% in the fusion group (p = 0.034). The overall surgical outcomes of patients with upper lumbar HIVD were satisfactory in this study without any major complications. More reliable satisfactory rates and better functional scores at the three-month postoperative follow-up were reported in the fusion group.

Abstract
OBJECTIVE Percutaneous endoscopic lumbar discectomy (PELD) is a popular surgical procedure for the treatment of lumbar disc herniation (LDH). However, a small proportion of patients will have poor surgical outcomes. We sought to identify the predictors for poor outcomes after PELD. METHODS A total of 241 patients who had undergone PELD were followed up. Their numerical rating scale (NRS) for pain and Oswestry Disability Index scores were analyzed. They were divided by outcome (excellent, good, fair, poor) using the MacNab criteria. Their clinical history, physical examination, imaging, and surgical findings were compared among the groups. Ordinal logistic regression analysis was used to identify independent predictors for poor outcomes. RESULTS The preoperative mean total NRS for back pain, NRS for leg pain, and Oswestry Disability Index scores were 4.3 ± 2.6, 5.6 ± 2.5, and 52.1% ± 23.0%. At 2 years after PELD, the corresponding scores had decreased to 1.2 ± 1.7, 0.9 ± 1.5, and 8.4% ± 11.2% (P < 0.001). The excellent, good, fair, and poor outcome rates were 44.4%, 31.5%, 17.4%, and 6.6%, respectively. Ordinal logistic regression analysis revealed that 2-level PELD (P = 0.001), a history of lumbar fusion (P = 0.007), and Modic changes (P = 0.011) were independent predictors for poor outcomes. Numbness was an independent predictor for excellent outcomes (P = 0.014). CONCLUSIONS PELD appears to be an effective surgery for LDH. Two-level PELD, a history of lumbar fusion, and Modic changes at the same level were independent predictors for poor outcomes after PELD. Patients with LDH with numbness were more likely to have excellent outcomes.

Abstract
BACKGROUND Lumbar disc herniations at the L1-L2 and L2-L3 levels have unique characteristics that result in worse surgical outcomes after traditional microdiscectomy compared with herniation at L3-L4. The purpose of this study was to evaluate the characteristics, clinical presentation, and outcomes of patients who underwent percutaneous endoscopic lumbar discectomy (PELD) at L1-L2 and L2-L3, compared with those who underwent PELD at L3-L4. METHODS We retrospectively evaluated the clinical data from 55 patients who underwent PELD for single-level lumbar disc herniation between 2008 and 2014, at a mean follow-up of 29.9 ± 16.4 months (12-month minimum; effective rate, 89.1%). Surgical duration; length of postoperative hospital stay; hospitalization cost; recurrence rate; Macnab criteria assessment; visual analog scale (VAS) of back pain, leg pain, and numbness; Japanese Orthopedic Association (JOA) low back pain score; and Oswestry Disability Index (ODI) before and after surgery were evaluated. RESULTS In the L1-L3 group, 76.9% of the patients had a positive femoral stretch test, compared with only 42.8% of those in the L3-L4 group (P < 0.05). Of the 49 patients with adequate follow-up, 17 (34.7%) exhibited excellent improvement, 23 (46.9%) had good improvement, and 6 (12.2%) had fair improvement according to the Macnab criteria. The VAS scores for back pain, leg pain, and numbness decreased significantly postoperatively in both groups, as did all other outcome measures (P < 0.05). CONCLUSIONS PELD is a safe and effective treatment for upper lumbar disc herniation and may compare favorably with the same procedure for lower lumbar disc herniation. In addition, the positive femoral stretch test was a relatively good diagnostic method for disc herniation at L1-L2 and L2-L3, compared with herniation at L3-L4.
