Abstract
Objective To formulate the most current, evidence-based recommendations regarding the epidemiology, clinical diagnosis, and radiographic diagnosis of lumbar herniated disk (LDH). Methods A systematic literature search in PubMed, MEDLINE, and CENTRAL was performed from 2012 to 2022 using the search terms "herniated lumbar disc", "epidemiology", "prevention" "clinical diagnosis", and "radiological diagnosis". Screening criteria resulted in 17, 16, and 90 studies respectively that were analyzed regarding epidemiology, clinical diagnosis, and radiographic diagnosis of LDH. Using the Delphi method and two rounds of voting at two separate international meetings, ten members of the WFNS (World Federation of Neurosurgical Societies) Spine Committee generated eleven final consensus statements. Results The lifetime risk for symptomatic LDH is 1-3%; of these, 60-90% resolve spontaneously. Risk factors for LDH include genetic and environmental factors, strenuous activity, and smoking. LDH is more common in males and in 30-50 year olds. A set of clinical tests, including manual muscle testing, sensory testing, Lasegue sign, and crossed Lasegue sign are recommended to diagnose LDH. Magnetic resonance imaging (MRI) is the gold standard for confirming suspected LDH. Conclusions These eleven final consensus statements provide current, evidence-based guidelines on the epidemiology, clinical diagnosis, and radiographic diagnosis of LDH for practicing spine surgeons worldwide.

Abstract
OBJECTIVES This study aimed to evaluate the clinical efficacy and safety of percutaneous endoscopic interlaminar discectomy (PEID) for treating highly downward-migrated disc herniation. METHODS We conducted a retrospective study on 39 patients with highly downward-migrated disc herniation who underwent PEID treatment between January 2015 and October 2020. The clinical outcomes, including the preoperative and postoperative visual analogue scale (VAS) for the back and leg, Oswestry Disability Index (ODI), and MacNab criteria for surgical success, were evaluated and compared to thirty-seven patients treated with posterior lumbar interbody fusion (PLIF). RESULTS The mean operation time of PEID was 93.00(77.00,110.00) min, while that of PLIF was 169.00(157.00,183.00) min. Continued improvement in both PEID and PLIF was observed in the VAS and ODI scores immediately after the surgery to the last follow-up. The VAS and ODI scores of PEID one week after surgery were significantly different from those of PLIF. One patient with recurrent lumbar disc herniation in the same segment improved after undergoing repeat PEID, two patients had dura tears, and conservative treatment helped relieve the symptoms. The overall percentage of patients with good to excellent results of PELD according to the modified MacNab criteria was 97.43%, while that of PLIF was 94.60%. CONCLUSIONS PEID has reliable efficacy and safety for treating highly downward-migrated disc herniation. And the long-term efficacy of PEID is comparable to PLIF. No severe complications occurred after surgery, and most patients' symptoms were relieved.

Abstract
Objective This article aims to discuss a novel surgical strategy, referred to as unilateral bi/multi-portal endoscopy (UME), which used a uniaxial spinal endoscope instead of an arthroscope in the traditional unilateral biportal endoscopy (UBE) surgical procedure in our study of the treatment of complicated lumbar degenerative diseases. Methods This retrospective study included 42 patients diagnosed with high-migrated lumbar disc herniation and bilateral spinal stenosis who underwent UME surgery from January 2021 to December 2021. Patients included 20 men and 22 women, with an average age of 55.97±14.92 years. The average follow-up period was 13.19 months. The demographic data, operation time (min), and complications were recorded and analyzed. The visual analogue scale (VAS), Oswestry Disability Index (ODI) scores were used to evaluate the surgical outcomes. Three-dimensional CT scans and MRI were conducted to evaluate the radiographic improvement. Results A total of 26 patients were diagnosed with lumbar disc herniation and 16 with lumbar spinal stenosis. All 42 patients underwent UME surgery and achieved satisfactory outcomes. The operation time was 154.46±46.09 min. The average follow-up time was 13.19±1.33 months. The preoperative back pain (VAS-Back) and the last follow-up VAS-Back were 3.84±1.00 and 0.70±0.46, respectively (P < 0.05). The preoperative leg pain (VAS-Leg) and the last follow-up VAS-Leg were 6.46±1.08 and 1.03±0.64, respectively (P <0.05). Significant differences existed between preoperative ODI scores (58.70±11.22%) and the last follow-up ODI scores (9.24±3.04%; P<0.05). All patients achieved significant pain relief and functional improvement after the surgery. No severe complications occurred, except for two cases of postoperative dysesthesia and one case suffered from vertebral compression fractures induced by a postoperative accidental injury. Symptoms of numbness disappeared within one week with treatment using dexamethasone and neurotrophic drugs. The vertebral fracture case recovered with percutaneous kyphoplasty treatment. Conclusion This study suggests that UME is a promising treatment strategy for high-migrated disc herniation and bilateral spinal stenosis.

Abstract
BACKGROUND Lumbar disc herniation (LDH) is one of the most common diseases of the spine, and migrated LDH is a more serious type, associated with nerve root function injury or abnormality. Regarding the increasing surgery adoption of treating migrated LDH, we aimed to investigate the clinical efficacy and safety of discectomy with a novel technique-one-hole split endoscope (OSE) technique. METHODS This was a retrospective analysis of migrated LDH treated between December 2020 and September 2021. Hospitalization time, operative duration, intraoperative blood loss, number of fluoroscopy exposures, incision length, postoperative facet preservation rate, number of excellent-good cases, lower back and leg visual analogue score (VAS), Oswestry Disability Index (ODI) and surgical complications were compared between high-grade migration group (82 cases) and low-grade migration group (148 cases). The Macnab criteria was used to evaluate the clinical outcome. The Shapiro‒Wilk test was used to test measurement data, and the χ2 test was used to test counting data. RESULTS There was no significant difference in hospitalization time, operative duration, intraoperative blood loss, number of fluoroscopy exposures, incision length or postoperative facet preservation rate between the two groups by independent sample t test or nonparametric test. At any time point, the lower back and leg VAS and ODI of the two groups were significantly improved compared to those before the operation, but there was no significant difference between the two groups at the same time point by two-way repeated measures ANOVA. There were two cases of postoperative nerve root stimulation symptoms in the high-grade migration group and three cases in the low-grade migration group. There was one patient reoperated in the high-grade migration group. There was no significant difference in number of excellent-good cases between the two groups. The overall excellent-good rate was 89.6%. CONCLUSION The OSE technique has the advantages of less trauma, faster recovery, complete removal of the nucleus pulposus and a satisfactory early clinical efficacy in the treatment of migrated LDH.

Abstract
OBJECTIVE High-grade migrated lumbar disc herniation (LDH) such as up-migrated and down-migrated discs are challenging pathologies to treat. High-grade migrated discs are usually sequestered and situated adjacent to the medial pedicle wall. This can be easily addressed if the pedicle is used as an access route. The authors present a retrospective case series of high-grade migrated LDH treated using a full endoscopic transforaminal approach. MATERIALS AND METHODS This is a retrospective case series. The clinical outcomes in the patients were evaluated according to improvement in the symptoms as suggested by improvement in Visual Analog Score (VAS) and Oswestry Disability Index (ODI) scores in the immediate postoperative period and at the final follow-up. The radiological outcomes were evaluated using postoperative magnetic resonance imaging and computed tomography scans. After the data were collected and tabulated, descriptive statistics were used for continuous variables. The t test was used to determine the significance of changes in the VAS and ODI scores. Statistical significance was set at P < 0.05. RESULTS Five patients underwent discectomy using the transpedicular technique, and the mean preoperative VAS scores for the back and leg were 7.2 ± 0.83 and 8.4 ± 0.54, respectively. The mean VAS scores at the final follow-up for the back was 0.2 ± 0.4 and 0 for the leg (P < 0.05). The mean preoperative ODI score was 72 ± 8.3, which improved to 6 ± 4.69 at the final follow-up (P < 0.05). All patients had a hospital stay of 1 day. CONCLUSIONS The full endoscopic transpedicular approach is a good option for treating highly migrated LDH. Surgical planning, including pedicle morphometry and the angle of the approach, should be undertaken preoperatively for the best results.

Abstract
INTRODUCTION Although the anatomy and pathology of lumbar disc herniation (LDH) have been clearly defined and classified in many studies, its imaging definition and classification still needs further clarification. This study intends to propose a novel classification and individualized surgical strategy for LDH based on preoperative magnetic resonance imaging (MRI). MATERIALS AND METHODS According to MRI features, LDH types were identified, and the corresponding surgical strategies were formulated to accurately remove the herniated discs while minimizing the disturbance to the normal disc. We retrospectively analyzed prospectively collected data of LDH patients who underwent surgery guided by this classification system. RESULTS This study included 357 patients with LDH who underwent tubular microdiscectomy. LDH was classified into four types based on MRI features. The inter- and intra-observer agreement using this classification was good. The follow-up results showed that surgery improved visual analog scale scores for low-back and leg pain and the Oswestry disability index in patients with different LDH types. The average recurrence rate at 1-5 years postoperatively was 5.62%. There was no significant difference in recurrence rates among the four LDH types (3.7-6.2%). MRI showed no significant differences in the Pfirrmann grade and disc height index of the operated segment between before surgery and 1-3 years after surgery. The operated segments did not show faster disc degeneration rates compared to adjacent proximal segments. CONCLUSIONS We proposed a novel classification system and an individualized surgical strategy for LDH based on preoperative MRI. Further, the surgical suitable interventions guided by this system achieved good clinical outcomes and mild recurrence rates.

Abstract
OBJECTIVE To investigate the effectiveness of the unilateral biportal endoscopy (UBE) technique in the treatment of high-grade migrated lumbar disc herniation (LDH). METHODS Between January 2020 and February 2021, 23 cases of high-grade migrated LDH were treated with discectomy via UBE. There were 14 males and 9 females, with a mean age of 48.7 years (range, 32-76 years). All patients had low back and leg pain. The disease duration ranged from 2 months to 7 years (median, 13 months). Lesion segments were L 3, 4 in 2 cases, L 4, 5 in 15 cases, and L 5, S 1 in 6 cases. The operation time, intraoperative blood loss, the time when the patients started to move off the floor, and postoperative complications were recorded. The effectiveness was evaluated using the visual analogue scale (VAS) score, the modified Oswestry disability index (ODI), and the modified MacNab criteria. RESULTS All operations were completed successfully, and no complication such as dural tear, epidural hematoma, nerve injury, or vascular injury occurred. The operation time ranged from 53 to 96 minutes, with an average of 71.0 minutes. The intraoperative blood loss ranged from 32 to 56 mL, with an average of 39.3 mL. All patients were removed the drainage tube and wore a lumbar brace to move off the floor around 1 to 2 days after operation. All patients were followed up 3-12 months after operation, with an average of 5.7 months. The VAS scores of low back pain and leg pain and the modified ODI at all postoperative time points were lower than those before operation, and the differences were significant ( P<0.05). The differences were significant ( P<0.05) when comparing the above indexes between the time points after operation. At last follow-up, the effectiveness was evaluated according to the modified MacNab criteria, and 17 cases were excellent, 4 cases were good, and 2 cases were fair, with an excellent and good rate of 91.3%. There was no recurrence of LDH during follow-up. CONCLUSION Discectomy via UBE is an effective method for the treatment of high-grade migrated LDH because of its flexibility, clear view, and wide range of intraoperative exploration, which can effectively reduce the risk of residual nucleus pulposus after operation.

Abstract
Understanding the degree of disc migration is essential in order to diagnose, treat, and assess the prognosis of migrated lumbar disc herniation (LDH). Based on anatomical configuration, we developed a simple six-level grading system for migrated lumbar disc herniation. We aimed to evaluate whether the new grading system was reliable and could replace the previous grading system. We selected 101 cases from our database. Two independent raters evaluated the magnetic resonance images using each grading system. Interobserver, intraobserver, and inter-grading system agreements were assessed using kappa statistics. The most common migration pattern was low-grade inferior migration. Interobserver agreements between the two readers showed substantial agreement in the first and second assessments (k = 0.753 and 0.756, respectively). The intraobserver agreement of reader 1 revealed substantial agreement (k = 0.733), while that of reader 2 revealed almost perfect agreement (k = 0.829). The strengths of the agreements of the new grading system were higher than those of the Lee-Kim grading system. The two grading systems agreed almost perfectly for most measurements. The new grading system was reliable and feasible to determine migrated LDH grade. It allowed for a more intuitive, objective measurement and helped select surgical options.

Abstract
Purpose Percutaneous endoscopic lumbar discectomy for the treatment of far-migrated lumbar disc herniation (LDH) is clinically challenging. The aim of this study was to compare the efficacy and safety of interlaminar endoscopic lumbar discectomy (IELD) and interlaminar microscopic lumbar discectomy (IMLD) for the treatment of far-migrated LDH. Materials and Methods We retrospectively analyzed 50 consecutive cases of far-migrated LDH treated by IELD or IMLD. Clinical data and outcomes were assessed before the operation and 1 day and 3, 12, and 24 months after the surgery using the visual analog scale (VAS) and Oswestry disability index (ODI). Modified MacNab criteria were used to evaluate patient satisfaction at the 24-month follow-up. Results A significant reduction in leg pain and improvement in ODI (P<0.01) were observed in both groups after surgery. Lower back pain (LBP) was reduced at 24 months postsurgery in the IELD group (P<0.05) but not in the IMLD group (P>0.05). There were significant intergroup differences in VAS LBP score at 1 day and 24 months postsurgery (p=0.01 and 0.02, respectively) and in ODI at 24 months (p=0.03). The rate of excellent or good outcome was 90.32% with IELD and 78.95% with IMLD (p=0.55). Hospital stay and time to ambulation were shorter in the IELD group than in the IMLD group, but the former had a longer operative time (p<0.01). Low and comparable complication rates were reported in the IELD (16.13%) and IMLD (10.53%) groups (p=0.70). Conclusion Both IELD and IMLD achieve favorable clinical results in the treatment of far-migrated LDH, with only minor complications. Compared to IMLD, LBP was significantly reduced with IELD presumably because it involved less trauma.

Abstract
INTRODUCTION This prospective case-control study aimed to establish the normal spectrum of early magnetic resonance imaging (MRI) findings in patients whose symptoms resolve after full endoscopic diskectomy (FED). We examined the changes in postoperative MRI findings and their relation to early clinical symptoms. METHODS In total, 33 patients underwent FED under local anesthesia. Clinical assessments and MRI examinations were performed preoperatively and immediately (within 1 week) and late (at 3 and 12 months) postoperatively. Residual disk bulging after surgery was classified into four grades compared with preoperative MRI findings: none (grade A), <25% (grade B), 25-75% (grade C), and >75% (grade D). RESULTS MRI at postoperative week 1 showed grade B residual disk bulging in 9 patients, grade C residual disk bulging in 8 patients, and grade D residual disk bulging in 16 patients. Improvement was seen at postoperative month 3 (grade A in 18 patients, grade B in 10 patients, and grade C in 5 patients) and at postoperative month 12 (grade A in 29 patients, grade B in 3 patients, and grade C in 1 patient). Visual analog scale scores and the Japanese Orthopaedic Association scores showed significant differences at 1 week, 3 months, and 12 months after surgery. CONCLUSION Postoperative MRI findings within 1 week of FED showed grade C or D residual disk material in 24 of 33 patients (73%). Clinical symptoms improved in the early postoperative period, even though residual disk bulging was present. Persisting residual bulging in the early stage following surgery may not correlate with clinical symptoms.

Abstract
BACKGROUND Full-endoscopic lumbar discectomy (FELD) is an alternative to posterior open surgery to treat a high-grade migrated herniated disc. However, because of the complexity of the surgery, success is dependent on the surgeon's skill. Therefore, patients are frequently treated using open discectomy. Anatomical constraints and technical difficulties can lead to the incomplete removal of high-grade migrated discs. METHODS We retrospectively reviewed patients who had undergone FELD performed by a single surgeon between January 2010 and January 2014 from a prospective spine registry in an institute. Perioperative records and data of the Oswestry Disability Index, visual analog scale scores (preoperatively and 2 weeks, 6 weeks, 3 months, 6 months, 1 year, 2 years, and 5 years after the operation), and MacNab criteria were collected. RESULTS Of 58 patients with a follow-up duration of > 5 years, (41 and 17 patients had undergone transforaminal endoscopic lumbar discectomy [TELD] and interlaminar endoscopic lumbar discectomy [IELD], respectively), the satisfaction rate was 87.8% (five unsatisfactory cases) for TELD and 100% for IELD. The overall percentage of patients with good to excellent results according to modified MacNab criteria was 91.3% (53/58 patients). Two patients had residual discs. Two patients needed an open discectomy due to recurrent disc herniation. One IELD patient received spinal fusion surgery due to segmental instability after 5 years. CONCLUSION FELD has a high success rate for the management of high-grade migrated herniated discs. In patients with high-grade disc migration from L1 to L5, TELD is effective and safe. However, for L4-L5 and L5-S1 high-grade upward and downward disc migration, IELD is the favorable option and provides high patient satisfaction.

Abstract
ABSTRACT Objective To evaluate the intra- and interobserver reliability of the Lee et al. classification for migrated lumbar disc herniations. Methods In 2018, Ahn Y. et al. demonstrated the accuracy of this classification for radiologists. However, magnetic resonance images are often interpreted by orthopedists. Thus, a cross-sectional study was conducted by evaluating the magnetic resonance images of 82 patients diagnosed with lumbar disc herniation. The images were evaluated by 4 physicians, 3 of whom were spinal orthopedic specialists and 1 of whom was a radiologist. The intra- and interobserver analysis was conducted using the percentage of concordance and the Kappa method. Results The report of the classifications used by the four observers had a higher proportion of “zone 3” and “zone 4” type classifications in both evaluation moments. The most affected anatomical levels were L5-S1 (48.2%) and L4-L5 (41.4%). The intra- and interobserver concordance, when comparing both moments evaluation of the complementary examinations of the participants involved, was classified as moderate and very good. Conclusions Lee’s classification presented moderate to very good intra- and interobserver reliability for the evaluation of migrated lumbar disc herniation. Level of evidence II; Retrospective Study.

Abstract
OBJECTIVE Anatomical barriers (e.g., pedicles, narrow foramina) can hinder direct access to, and removal of, disc fragments that have migrated far downward. Using transforaminal full-endoscopic lumbar discectomy (FELD), we devised a modified technique, the suprapedicular retrocorporeal approach, for herniations in which the disc has migrated to the axilla of the traversing nerve roots. In the present report, we have described our preliminary results. METHODS Soft, highly downward-migrated disc herniation was treated with transforaminal FELD through the suprapedicular retrocorporeal approach in 22 patients from June 2017 to May 2019. The clinical outcomes were evaluated, including the preoperative and postoperative visual analog scale scores for the back and leg, Oswestry disability index, and MacNab criteria for surgical success. RESULTS The affected discs were at L4-L5 in 14 patients, L3-L4 in 6 patients, and L5-S1 in 2 patients. In each case, the affected disc was successfully removed using the suprapedicular retrocorporeal approach. The mean follow-up was 18.1 ± 5.7 months. The mean visual analog scale scores for back and leg pain improved significantly (P < 0.05 for both). The mean Oswestry disability index had decreased from 62.5 ± 14.2 preoperatively to 10.5 ± 5.9 postoperatively (P < 0.05). Using the MacNab criteria, 13 patients reported excellent outcomes and 9, good outcomes. No complications or recurrence developed during follow-up. CONCLUSIONS The suprapedicular retrocorporeal technique is a feasible and effective surgical option in transforaminal FELD for the treatment of herniation in which the disc has migrated to the axilla of the traversing nerve roots.

Abstract
As an essential component of minimally invasive spine surgery, endoscopic spine surgery (ESS) has continuously evolved and has been accepted as a practical procedure by the worldwide spine community. Especially for lumbar disc herniation (LDH), the percutaneous endoscopic or full-endoscopic discectomy technique has been scientifically proven through randomized controlled trials and meta-analyses to be a good alternative to open discectomy. The initial concept of endoscopic spine discectomy was concerned with indirect disc decompression using various instruments such as blind forceps, a nucleotome, laser, radiofrequency coblation, and some chemical agents. The main surgical field has been shifted from the intradiscal space to the epidural space. Precise and selective discectomy for extruded LDH in the epidural space under high-quality endoscopic visualization is now feasible. Furthermore, the medical applications of ESS is broadening to include spinal stenosis, segmental instability, infection, and even intradural lesions. In this review article, I describe the history of endoscopic spine discectomy and decompression techniques, as well as evolution of the paradigm. This history may help indicate the future of practical ESS.

Abstract
OBJECTIVE To report the technical notes and clinical outcome of percutaneous isthmus foraminoplasty and full-endoscopic lumbar discectomy (PIF-FELD) for the treatment of very highly upmigrated lumbar disc herniation (VHUM-LDH). PATIENTS AND METHODS From January 2014 to December 2017, 16 patients with VHUM-LDH underwent PIF-FELD surgery. A 10-mm-diameter semi-open foraminoplasty was performed on the dorsal side of the upper intervertebral foramen with lateral isthmus resection by a safe trephine system, in which the facet joint was not injured. Full-endoscopic transforaminal fragmentectomy in the spinal canal and discectomy in the intervertebral space were performed simultaneously. Magnetic resonance imaging of the lumbar spine was reexamined on the second day and 3 months after the operation to evaluate the completeness of the disc fragmentectomy and nerve decompression. The patients were followed up on the visual analog scale (VAS) of lumbar pain and leg pain and Oswestry Disability Index on the second day, 3 months, 6 months, 1 year, and 2 years after operation. The MacNab score and nerve root function recovery were evaluated at 2 years postoperative follow-up. RESULTS All operations were successfully completed without any change in the surgical method. During the operation, 5 patients were found to have a single sequestered fragment, and the remaining 11 patients had multiple sequestered fragments. There were no complications (e.g., dural tear and nerve injury) during the operation, and no complications (e.g., infection, cerebrospinal fluid leakage, exacerbation of nerve root function injury, and recurrence of intervertebral disc herniation) occurred. Postoperative reexamination of lumbar magnetic resonance imaging in all patients showed complete disc fragmentectomy and adequate nerve decompression. The postoperative low back pain VAS and leg pain VAS scores and Oswestry Disability Index on the second day, 3 months, 6 months, 1 year, and 2 years after operation were significantly improved compared with preoperatively (P < 0.01). At 2 years follow-up, the sensation and muscular strength of the affected nerve root innervation area were significantly restored (P < 0.05), but tendon reflex function was not significantly restored (P > 0.05). At 2 years follow-up, MacNab scores included 6 excellent, 9 good, and 1 fair. CONCLUSIONS PIF-FELD is a safe and effective minimally invasive spine surgery technique for VHUM-LDH.

Abstract
Degenerative disc disease is a leading cause of chronic back pain in the aging population in the world. Sinuvertebral nerve and basivertebral nerve are postulated to be associated with the pain pathway as a result of neurotization. Our goal is to perform a prospective study using radiofrequency ablation on sinuvertebral nerve and basivertebral nerve; evaluating its short and long term effect on pain score, disability score and patients’ outcome. A review in literature is done on the pathoanatomy, pathophysiology and pain generation pathway in degenerative disc disease and chronic back pain. 30 patients with 38 levels of intervertebral disc presented with discogenic back pain with bulging degenerative intervertebral disc or spinal stenosis underwent Uniportal Full Endoscopic Radiofrequency Ablation application through either Transforaminal or Interlaminar Endoscopic Approaches. Their preoperative characteristics are recorded and prospective data was collected for Visualized Analogue Scale, Oswestry Disability Index and MacNab Criteria for pain were evaluated. There was statistically significant Visual Analogue Scale improvement from preoperative state at post-operative 1wk, 6 months and final follow up were 4.4 ± 1.0, 5.5 ± 1.2 and 5.7 ± 1.3, respectively, p < 0.0001. Oswestery Disability Index improvement from preoperative state at 1week, 6 months and final follow up were 45.8 ± 8.7, 50.4 ± 8.2 and 52.7 ± 10.3, p < 0.0001. MacNab criteria showed excellent outcomes in 17 cases, good outcomes in 11 cases and fair outcomes in 2 cases Sinuvertebral Nerve and Basivertebral Nerve Radiofrequency Ablation is effective in improving the patients’ pain, disability status and patient outcome in our study.
