Abstract
STUDY DESIGN Retrospective clinical study. OBJECTIVE The purpose of this study was to establish a novel classification of migrated lumbar disk herniation (LDH) based on magnetic resonance imaging and provide appropriate treatment strategies for each type through algorithms. SUMMARY OF BACKGROUND DATA Full-endoscopic lumbar discectomy is a surgical technique that has been developed rapidly in recent years. For migrated LDH, few surgeons currently classify it with multiplanar positioning, and there is no consensus on the choice of treatment strategy. Therefore, we established a new multiplanar classification criteria that can localize the lesions more accurately than previous studies. METHODS A total of 263 eligible patients from March 2017 to March 2022 were included. Protrusions for each patient were located based on our classification and the surgical approach was selected according to our algorithms. The clinical symptoms of all patients before surgery, and at 1 day, 1 month, 3 months, 6 months, and 12 months after surgery were collected. Evaluations were performed using visual analogue scale (VAS), Oswestry Disability Index (ODI) and modified MacNab criteria. We used the chi-squared test, one-way analysis of variance (ANOVA), and t-test to compare perioperative results and postoperative 3-month, 6-month, and 12-month follow-up results. RESULTS VAS (low back pain) scores were reduced from 5.33 ± 2.67 to 0.73 ± 0.77 (p < 0.001), and VAS (leg pain) scores were reduced from 7.44 ± 2.21 to 0.37 ± 0.51 (p < 0.001). ODI scores improved from 58.46 ± 8.04 to 12.57 ± 2.51 (p < 0.001). According to the modified MacNab criteria, the excellent and good rate reached 92.78% at the 12-month follow-up. Twenty-six patients developed complications, all of which improved after treatment. Recurrence occurred in 13 patients, and four of them underwent secondary surgery. CONCLUSIONS This is an innovative classification method using multi-plane positioning, and the algorithm used with it can help surgeons make appropriate choices when using endoscopic technology to treat migrated LDH. Statistical analysis of follow-up data confirmed that this is a safe and effective strategy.

Abstract
STUDY DESIGN Biomechanical cadaveric study. OBJECTIVE The goal of this study was to analyze the effects of an endoscopic transpedicular approach with different drill diameters (6 and 8 mm) and compare them with the intact native side. In addition, the influence of bone quality on the resistance of the pedicle was investigated. SUMMARY OF BACKGROUND DATA Clinical studies have repeatedly highlighted the benefits of endoscopic transpedicular decompression for downmigrated lumbar disc herniations. However, the biomechanical effects on pedicle stability have not been studied up to now. MATERIALS AND METHODS Twenty-four vertebras originating from four fresh-frozen cadavers were tested under uniaxial compression load in a ramp-to-failure test: (1) the tunneled pedicle on one side, and (2) the native pedicle on the other side. Twelve lumbar vertebrae were assigned to drill diameter of 6 mm and the other 12 to diameter of 8 mm. RESULTS The median ratio of sustained force for the operated side compared with the intact contralateral side is equal to 74% (63-88) for both drill diameters combined. An 8 mm transpedicular approach recorded an axial resistance of 77% (60-88) compared with the intact contralateral side ( P =0.002). A 6 mm approach resulted in an axial resistance of 72% (66-84) compared with the intact opposite side ( P =0.01). No significant difference between the two different drill diameters was recorded ( P =1). For all three subgroups (intact, 8 mm, 6 mm) the Hounsfield units-values and the absolute resistance force showed significant correlations (intact: ρ=0.859; P <0.001; 8 mm: ρ=0.902; P <0.001; 6 mm: ρ=0.835; P <0.001). CONCLUSION The transpedicular approach significantly reduces the axial resistance force of the pedicle, which may lead to pedicle fracture. Bone quality correlated positively with the absolute resistance force of the pedicle, whereas the influence of the drill hole diameter plays only a limited role.

Full Endoscopic Transpedicular Discectomy for a Rostrally Migrated L5-S1 Disc Herniation in the Setting of Previous Lumbar Surgery: A Case Report With Intraoperative Video. Oper Neurosurg (Hagerstown) 2024:01787389-990000000-01212. [PMID: 38953650 DOI: 10.1227/ons.0000000000001237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 04/23/2024] [Indexed: 07/04/2024] Open
Abstract
BACKGROUND AND IMPORTANCE The surgical management of rostral disc herniations at L5-S1 poses challenges for conventional endoscopic approaches, particularly in patients who have had previous lumbar surgery. We present a full endoscopic transpedicular discectomy (FETD), whereby a pediculotomy is created to pass an endoscope through the pedicle for intracanal access. This addresses anatomic obstacles and potential complications associated with other endoscopic and minimally invasive or open techniques. To date, this is the only article to highlight this approach with a case report and intraoperative video. CLINICAL PRESENTATION A 76-year-old man with a history of L3-S1 laminectomy presented with left leg pain and a near-complete left foot drop. An MRI revealed a left paracentral rostrally migrated disc herniation arising from L5-S1 with impingement of the exiting left L5 nerve root at the inferomedial aspect of the pedicle of L5. The patient consented to the FETD procedure. Using sequential reamers of increasing diameter and a high-speed burr, a superolateral to inferomedial pediculotomy was performed. This approach allowed us to target the pathology at the point of maximum compression without traversing the prior operative field. A transforaminal endoscopic approach was not possible with the iliac crest obstructing rostral angulation. The disc was successfully removed without any intraoperative complications, and after surgery, the patient's radiculopathy resolved without any radiographic evidence of instability. CONCLUSION FETD is a unique approach that demonstrates the versatility of endoscopic spine surgery, offering advantages over conventional approaches particularly for rostral disc herniations at L5-S1 in the setting of prior lumbar surgery.

World Neurosurg 2023; 173:e408-e414. [PMID: 36805502 DOI: 10.1016/j.wneu.2023.02.065] [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: 12/27/2022] [Revised: 02/12/2023] [Accepted: 02/13/2023] [Indexed: 02/20/2023]
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
STUDY DESIGN A systematic review of the literature to develop an algorithm formulated by key opinion leaders. OBJECTIVE This study aimed to analyze currently available data and propose a decision-making algorithm for full-endoscopic lumbar discectomy for treating lumbar disc herniation (LDH) to help surgeons choose the most appropriate approach [transforaminal endoscopic lumbar discectomy (TELD) or interlaminar endoscopic lumbar discectomy (IELD)] for patients. SUMMARY OF BACKGROUND DATA Full-endoscopic discectomy has gained popularity in recent decades. To our knowledge, an algorithm for choosing the proper surgical approach has never been proposed. MATERIALS AND METHODS A systematic review of the literature using PubMed and MeSH terms was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Patient samples included patients with LDH treated with full-endoscopic discectomy. The inclusion criteria were interventional research (randomized and nonrandomized trials) and observation research (cohort, case-control, case series). Exclusion criteria were case series and technical reports. The criteria used for selecting patients were grouped and analyzed. Then, an algorithm was generated based on these findings with support and reconfirmation from key expert opinions. Data on overall complications were collected. Outcome measures included zone of herniation, level of herniation, and approach (TELD or IELD). RESULTS In total, 474 articles met the initial screening criteria. The detailed analysis identified the 80 best-matching articles; after applying the inclusion and exclusion criteria, 53 articles remained for this review. CONCLUSIONS The proposed algorithm suggests a TELD for LDH located in the foraminal or extraforaminal zones at upper and lower levels and for central and subarticular discs at the upper levels considering the anatomic foraminal features and the craniocaudal pathology location. An IELD is preferred for LDH in the central or subarticular zones at L4/L5 and L5/S1, especially if a high iliac crest or high-grade migration is found.

Abstract
PURPOSES To analyze the clinical and radiographic risk factors that might predict incomplete clinical improvement after transforaminal endoscopic lumbar discectomy (TELD). METHODS A retrospective analysis was conducted from 194 consecutive patients who underwent TELD due to lumbar disc herniation (LDH). Patients with incomplete clinical improvement were defined from patient-reported outcomes of poor improvement in pain or disability after surgery and patient dissatisfaction. Clinical and radiographic characteristics were evaluated to identify predicting factors of poor outcomes. RESULTS Of 194 patients who underwent TELD procedures, 32 patients (16.5%) had incomplete clinical improvement and 12 patients (6.1%) required revision surgery. The mean ages were 46.4 years and most of the patients suffered from predominant leg pain (48.9%). The most common surgical level was L4-5 (63.9%). Overall, the Oswestry Disability Index (44.3-15), visual analog scores of back pain (4.9-1.8) and leg pain (7.3-1.6) were significantly improved after surgery. Multivariate logistic regression analysis demonstrated that high body mass index, history of previous surgery, preoperative disability, weakness, and disc degeneration were related to incomplete clinical improvement. There were 15 recurrent LDH (7.7%) with a total of 12 revision surgeries (6.2%). CONCLUSIONS We identified independent risk factors associated with incomplete clinical improvement following TELD, including overweight, significant preoperative disability or weakness and history of previous surgery. Advanced age, disc degeneration, vacuum phenomenon, and spondylolisthesis were also possible risk factors. Recognizing these risk factors would help decide whether patients are good candidates for TELD, and optimize the surgical planning preoperatively to achieve good surgical results.

Abstract
Purpose We aimed to comprehensively analyze the current status, hotspots, and trends in full endoscopic spine surgery (FESS) research using bibliometric analysis and knowledge domain mapping. Methods The Web of Science database was used to screen FESS-related articles published between January 1, 1993 and June 10, 2022. The evaluation involved the following criteria: total number of articles; H-index; and contributions from countries/regions, institutions, journals, and authors. Results A total of 1,064 articles were included. Since 2016, there have been a significant number of publications in the field of FESS. The country/region contributing the largest number of articles was China (37.8%), followed by South Korea (24%), the United States (16.1%), Japan (5.7%), and Germany (5.1%). South Korea (35) had the highest H-index, followed by the United States (27), China (22), Japan (21), and Germany (20). World Neurosurgery (15.7%) published the largest number of FESS-related articles. However, among the top 10 most cited articles, six were published in Spine. The author who contributed the most was S.H. Lee (5.4%), and the largest number of contributions in this field originated from Wooridul Spine Hospital (South Korea; 6.1%). Notably, six of the 10 most published authors in this field were from South Korea. Of the top five productive institutions, three were from South Korea. The keywords with the strongest citation bursts in the field of FESS were “lumbar spine,” “discectomy,” “interlaminar,” “surgical technique,” “follow-up,” “excision,” “thoracic spine,” and “endoscopic surgery.” The 10 clusters generated in this study were: “endoscopic discectomy” (#0), “thoracic myelopathy” (#1), “recurrent lumbar disc herniation” (#2), “low back pain” (#3), “cervical vertebrae” (#4), “lumbar spinal stenosis” (#5), “transforaminal lumbar interbody fusion” (#6), “radiation exposure” (#7), “management” (#8), and “lumbar spine” (#9). Conclusion Global research on FESS is mostly concentrated in a few countries/regions and authors. South Korea has made the largest contribution to the field of FESS. Based on the most cited keyword bursts and clusters, the focus of FESS research was found to include its indications, management, and applications.

Abstract
Background To evaluate the clinical outcome of full endoscopic discectomy using a novel trajectory via a transpedicular approach. Method Thirty-five patients were enrolled in this retrospective study between July 2014 and October 2019 in the Beijing Haidian Hospital. All patients were treated with full-endoscopic lumbar discectomy via a transpedicular approach with an oblique trajectory. The imaging parameters, including pedicle height and angle of trajectory, were recorded. The preoperative and postoperative clinical data were collected for statistical analysis. Results All patients underwent successful surgery without severe complications. We compared the visual analogue scale and Oswestry disability index scores before and after surgery. The differences were statistically significant (p < 0.05). According to the modified Macnab criteria, the good-to-excellent rate was 85.7% at the last follow-up. The average angles of trajectory in the sagittal and coronal planes were 34.5° ± 2.9° and 47.1° ± 5.0°, respectively. Conclusion The new trajectory of the transpedicular approach with a full endoscopic technique for an extremely downward-migrated disc herniation showed excellent results in a small sample study. A precise surgical plan is required, comprising measurements of the pedicle height and angle of the bone tunnel.

Abstract
PURPOSE To introduce a new fully endoscopic visualized laminar trepanning approach with a periendoscopic trephine under local anesthesia for resection of highly migrated lumbar disc herniation (LDH) and report the clinical outcomes of one year follow-up. METHODS Twenty-one patients with highly migrated LDH who underwent percutaneous endoscopic lumbar discectomy via the laminar trepanning approach from June 2019 to August 2020 were retrospectively reviewed. Patient-Reported Outcomes Measurement Information System (PROMIS) Short Forms-Pain Interference (PI) and Physical Function (PF) were selected as outcome measures. The operating duration and complication were documented. RESULTS The average age of the 21 patients (15 males, 6 females) was 37.8 ± 6.0 years (29-52 years). Disc migration originated from L4/5 in 19 patients, L5/S1 in two patients. The mean operative duration was 54.1 ± 9.0 minutes (42-79 min). All patients were followed up to 12 months after the operation. PROMIS PI T-scores decreased significantly from pre-operatively mean 68.6 ± 2.4 to 54.4 ± 1.9 (P < 0.001) and 47.1 ± 4.3 (P < 0.001) at six weeks and 12 months, respectively. PROMIS PF T-scores improved significantly from pre-operatively mean 26.7 ± 4.7 to 44.3 ± 4.2(P < 0.001) and 58.4 ± 4.0 (P < 0.001) at six weeks and 12 months, respectively. No complications and disc herniation recurrences occurred. CONCLUSION The targeted full endoscopic laminar trepanning under local anesthesia with a visualized periendoscopic trephine offers a safe, efficient and cost-effective option for the resection of highly migrated LDH.

Abstract
A ridit analysis of results of transpedicular endoscopic and translaminar microsurgical surgeries for sequester migration to the second and third McCulloch's windows was carried out. The authors assessed pain syndrome, quality of life and neurological impairment. OBJECTIVE To compare the outcomes of transpedicular and translaminar sequestrectomy for lumbar disc herniation and sequester migration to the second and third McCulloch's windows. MATERIAL AND METHODS We analyzed treatment outcomes in 51 patients with lumbar disc herniation and severe sequester migration. We assessed lumbar and leg pain syndrome using then visual analogue scale, neurological impairment using the adapted Nurik scale and quality of life using the Oswestry questionnaire and the MacNab scale in early postoperative period, as well as in 2 weeks, 6 and 12 months after surgery. Ridit analysis was used for statistical processing of data. RESULTS Transpedicular sequestrectomy was performed in 24 patients, translaminar sequestrectomy - in 27 cases. Groups were comparable by gender, size and location of sequestration, somatic and neurological status, as well as pain severity. There was a higher probability of back (0.39) and leg (0.364) pain regression, neurological recovery (0.446) and improvement of quality of life according to the Oswestry questionnaire (0.389) after transpedicular surgery. According to the MacNab scoring system, excellent and good results were obtained in 84.21% and 15.79% of patients in 6 months after transpedicular surgery. In the second group, excellent, good and satisfactory results were obtained in 63%, 25.9% and 11.1% of patients, respectively. CONCLUSION Herniated intervertebral discs with severe sequester migration should be divided in accordance with localization of the main sequestration. Transpedicular endoscopic approach is advisable for sequester in the third and rarely the second McCulloch's windows. Translaminar microsurgical approach is preferred for sequestration in the second and rarely the third McCulloch's windows. Clinical outcomes after translaminar microsurgical sequestrectomy and transpedicular endoscopic surgeries are similar. However, postoperative back and leg pain regression, neurological recovery and improvement of quality of life according to the Oswestry scoring system are more common after transpedicular surgery.

A novel vertebral trench technique (VTT) involving transforaminal endoscopic lumbar foraminotomy (TELF) for very highly up-migrated lumbar disc herniation above L5. BMC Musculoskelet Disord 2021; 22:693. [PMID: 34391400 PMCID: PMC8364045 DOI: 10.1186/s12891-021-04548-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 07/26/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) has become popular for the treatment of symptomatic lumbar disc herniation (LDH). The very highly up-migrated lumbar disc herniation (VHUM-LDH) is difficult to remove under PELD. The purpose of this research is to investigate the feasibility, clinical efficacy and operative nuances of a novel VTT involving TELF for this type of herniation. METHODS Eleven patients with very highly up-migrated LDH who underwent VTT involving TELF discectomy from May 2016 to May 2019 were included in this study. The operative time, length of hospital stay, and postoperative complications were recorded. Pre-and postoperative radiologic findings were investigated. All the patients were followed more than 1 year. The visual analogue score (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA) scores and modified MacNab criteria were used to assess surgical efficacy. RESULTS All the 11 patients underwent successful surgery. We compared the VAS, ODI, and JOA scores before and after surgery. The differences were statistically significant (P < 0.05). According to the modified MacNab criteria, 10 patients were assessed as "excellent", 1 patient was assessed as "good" at the last follow up. CONCLUSION The novel VTT involving TELF discectomy is a supplement to the traditional PELD. This technique enables the endoscope with working cannula to get closer the sequestrated nucleus pulposus without irritating the exiting nerve root, and facilitates the nucleus pulposus be removed successfully under direct visualization. The VTT involving TELF discectomy can be a safe, effective and feasible surgical procedure for the treatment of LDH with very highly up-migrated.

Functional outcomes of full-endoscopic spine surgery for high-grade migrated lumbar disc herniation: a prospective registry-based cohort study with more than 5 years of follow-up. BMC Musculoskelet Disord 2021; 22:58. [PMID: 33422040 PMCID: PMC7797117 DOI: 10.1186/s12891-020-03891-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 12/16/2020] [Indexed: 11/10/2022] Open
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
BACKGROUND Surgical treatment of intervertebral disc herniation with a high degree of migration (beyond the vertebral pedicle) is a difficult problem without an unambiguous solution. In this manuscript, we compare the effectiveness of transpedicular endoscopy and standard discectomy in the treatment of patients with this disease. OBJECTIVE To compare transpedicular endoscopic sequestrectomy and discectomy in the treatment of lumbar intervertebral disc herniation with a high degree of migration. MATERIAL AND METHODS There were 28 patients divided into 2 groups: group 1 - 13 patients after transpedicular endoscopic sequestrectomy, group 2 - 15 patients after discectomy. RESULTS Transpedicular endoscopic sequestrectomy ensured significantly better intraoperative parameters (incision length, blood loss, surgery time) (p<0.01). In both groups, postoperative VAS score of leg pain was significantly reduced within a day after surgery from 7.4±1.3 to 0.7±0.7 and from 7.1±1 to 0.8±0.5, respectively. In the 1st group, VAS score of back pain regressed from 5.2±0.7 to 1.1±0.89 by the end of the 1st postoperative day. This value was 0.6±0.5 a year later. In the 2nd group, VAS score of back pain regressed from 4.9±1 to 2.5±0.9 by the end of the 1st postoperative day. This value was 2.8±2.3 a year later. According to McNab clinical outcome scale, excellent and good results after transpedicular endoscopic sequestrectomy were obtained in all 13 (100%) patients, after discectomy - in 80% of cases. CONCLUSION Transpedicular endoscopic sequestrectomy is optimal for intervertebral disc herniation with a high degree of migration due to fast postoperative recovery and no complications.

Abstract
Background. Highly migrated disc herniations are usually localized in the area of pars interarticularis medially to the vertebral pedicle. Removal of disk herniations of this localization is a difficult technical task.The study objective is to demonstrate the effectiveness of the transpedicular endoscopic discectomy in the treatment of patients with highly migrated disc herniations.Materials and methods. The results of treatment of 12 patients with Macnab zone herniations who were in hospital from 2016 to 2018 were analyzed. All patients underwent transpedicular endoscopic sequestrectomy.Results. Leg pain after surgery regressed in all patients from the initial 7.41 points (visual-analog scale) to 0.67 points by the end of the 1st day, and it was 0.35 points a year later. The average level of back pain by VAS before surgery was 5.25, on the 1st day after surgery – 1.25 points, 1 year after – 0.67 points. Neurological disorders completely regressed in 10 (91.6 %) patients, there were a slight residual L4 dermatome hypesthesia in 2 patients, without disrupting their quality of life. The average Oswestry Disability Index before surgery was 69.17, and 1 year after surgery was 14.12. There were no complications and reoperations.Conclusion. Transpedicular endoscopic discectomy allowed us to achieve good treatment results in patients with migration of a lumbar hernia by the pedicle. It can be a safe and effective alternative to the transforaminal or interlaminar endoscopic technique.

Abstract
Lumbar disc herniation (LDH) comprises one of the most common causes of low back pain. 35%–72% of LDH is associated with disc fragment migration. The migration of the disc fragments can be high-grade up, low-grade up, high-grade down, and low-grade down. Spine surgeons deal with unique challenges during surgical management of migrated discs. Operational challenges with open surgery include extensive lamina excision, pars excision, and potential for iatrogenic instability without fixation. In contrast, rigid instruments and poor visualization are the challenges with transforaminal endoscopic spine surgery (ESS). Hence interlaminar approach with ESS is an excellent choice with these migrated LDH. The creation of a translaminar crater in the cranial lamina without dealing with the interlaminar window or ligamentum flavum could be an excellent option to deal with these herniations face front. The lamina is the only anatomical barrier between the endoscope and the migrated disc fragment. Hence with a translaminar approach, unnecessary flavectomy can be avoided. In this technical report and video, we demonstrate the surgical technique of performing the translaminar ESS for highly upmigrated LDH with the preservation of optimal natural anatomy.

Abstract
Transforaminal endoscopic lumbar discectomy (TELD) with the outside-in technique can be applied to nearly all cases of lumbar disc herniation (LDH), and transpedicular endoscopic lumbar discectomy can be used to treat highly migrated LDHs. The purpose of this study was to outline these 2 outside-in surgical techniques and to present their clinical outcomes. Between January 2018 and January 2019, a total of 137 patients underwent either transforaminal or transpedicular endoscopic lumbar discectomy. We performed TELD in 124 patients and transpedicular endoscopic lumbar discectomy in 13 cases. All surgical procedures were performed under conscious sedation. The patients’ mean age was 51.3 years; 51 were women and 86 were men. The overall disc recurrence rate was 5.12%. Visual analogue scale scores decreased significantly in both groups. According to the MacNab criteria, good and excellent results were obtained in 92.74% of patients after transforaminal and in 92.30% of patients after transpedicular endoscopic LDH treatment. The results suggest that TELD with the outside-in technique can be effective for the treatment of most cases of LDH. Transpedicular endoscopic lumbar discectomy can be considered as an alternative treatment for highly migrated LDH.

Abstract
INTRODUCTION One of the most challenging occurrences in full-endoscopic surgery for lumbar disc protrusions are up-migrated or down-migrated herniations. Those occurrences are difficult to retrieve with transforaminal or interlaminar approaches. PRESENTATION OF CASE We describe our experience in dealing with a right paramedian down-migrated L3-L4 disc herniation. The patient underwent full endoscopic transpedicular endoscopic discectomy (FETD), by reaming the right L4 peduncle for intracanal access and fragment retrieval. We also reviewed the recent literature to summarize the advantages of transpedicular approaches, along with current indications and contraindications for this procedure. DISCUSSION We highlighted how FETD is safe and feasible for down-migrated and up-migrated disc herniation showing excellent results in our patient and in the small cohorts of patients already published in the literature. CONCLUSION FETD was effective in treating up-migrated and down-migrated disc herniation, as well as discal cysts, showing the feasibility and safety of the technique from any level from L1 to S1.

Abstract
Abstract
Background and Study Aims Technically and anatomically, accessing a high-grade migrated lumbar disk herniation (LDH) using traditional full endoscopic lumbar diskectomy (FELD) approaches (either transforaminal or interlaminar) is challenging. The objective of this study was to present an effective and safe surgical approach for high-grade up-migrated LDH by translaminar FELD.
Patients and Methods Thirteen patients with soft high-grade up-migrated LDH treated with a translaminar FELD between May 2015 and July 2018 were reviewed in this study. Five of these patients had very high-grade up-migration. Clinical outcomes were assessed including preoperative and postoperative visual analog scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), and MacNab criteria.
Results Overall, 7 of the 13 patients had disk-fragment migration at L4–L5: three at L5–S1, two at L3–L4, and the remaining one at L2–L3. In all cases, the highly up-migrated LDH was removed successfully through the translaminar approach, as confirmed by postoperative magnetic resonance imaging. The improvements of VAS for back and leg pain were 4.5 ± 0.9 to 1.3 ± 1.3 and 7.1 ± 1.0 to 1.6 ± 0.7, respectively (both p < 0.05). The ODI decreased from preoperative 41.9 ± 6.0 to postoperative 13.0 ± 4.1 (p < 0.05). According to the MacNab criteria, the satisfaction rate was 92.3% (excellent or good outcomes). None of the patients experienced any perioperative complications or recurrence during the follow-up period.
Conclusion Although full endoscopic technique via the translaminar keyhole route may not be used as a routine surgical approach, it could serve as a feasible alternative method for patients with highly up-migrated disk herniation.

Abstract
Endoscopic surgery for highly downmigrated disc herniation at level L5-S1 is a challenging technique. Most surgeons prefer the interlaminar access because of the special anatomy of the L5-S1 disc level, i.e., narrow neuroforamen and large interlaminar window. Transforaminal access to the neuroforamen L5-S1 is difficult in cases with high iliac crest.
