Background: Full-endoscopic interlaminar discectomy (FEID) is widely applied for the treatment of lumbar disc herniation (LDH) and satisfactory short-term outcomes have been achieved. However, the long-term evaluation for this technique is still lacking, especially the comparison between FEID and microendoscopic discectomy (MED). Objective: To evaluate the clinical outcome of FEID technique in comparison with MED for singlelevel LDH with a minimum of 5-year follow-up. Study Design: Retrospective study. Setting: Inpatient surgery center. Methods: A total of 152 patients with single-level LDH located at either L4-L5 or L5-S1 who underwent either FEID or MED from August 2008 to April 2011 at our hospital were enrolled in this study. General parameters including operative time, length of hospital stay, mean time to return to work, complications, and recurrences were recorded. Clinical outcomes were evaluated using visual analog scale (VAS) for low back and leg pain, Oswestry Disability Index (ODI) for functional assessment, and modified MacNab criteria for patient satisfaction. Results: At the final follow-up, the VAS of leg and back pain decreased from 7.6 ± 1.6 and 3.1 ± 2.2 points preoperatively to 1.6 ± 1.2 and 1.7 ± 0.9 at the final follow-up, respectively (P < 0.05). The ODI score was 69.5% ± 10.5% preoperatively, and declined to 21.8% ± 7.0% at the final follow-up (P < 0.05). VAS, ODI, and modified MacNab criteria of the FEID group were improved compared to the control group though there were no statistically significant differences between the 2 groups. Limitations: This was a retrospective study with a relatively small sample size. Additionally, this study contained only clinical outcomes, without long-term radiological outcomes. Conclusions: The application of FEID achieved similar satisfactory long-term clinical outcomes for the surgical treatment of LDH as MED. However, compared with MED, FEID exhibits advantages including less operation time, shorter hospital stay, and faster postoperative recovery.

Introduction: Lumbar disc herniation (LDH) is one of the most common causes for low back pain and related disabilities. Surgery is indicated in patients who do not respond to the conservative measures for at least 6 weeks or symptoms are worsened. Microendoscopic discectomy (MED) is a well-accepted minimally invasive surgical technique with similar results compared to open surgery. The purpose of this study was to evaluate the clinical outcome, functional improvement and analyze complications during MED. Methods: A retrospective analysis was conducted in 156 patients who were operated for single or double level LDH using MED between 2016 and 2018. All patients were evaluated for pain and disability using visual analogue scale (VAS) and Oswestry disability index (ODI), respectively. Modified MabNab’s criteria used to evaluate overall outcome of surgery. Operation time, estimated blood loss (EBL), hospital stay and time to return back to previous activities were evaluated. Complications and revisions were noted during follow-up to analyze clinical results. Paired t-test was used to evaluate statistical difference in VAS and ODI score during follow-up. Results: All patients were followed up at 6 weeks, 3 months, 6 months, 1 year and yearly thereafter postoperatively. Average follow-up was 25.5±9.7 months and average age was 45.0±12.7 years. Average VAS scores improved significantly from preoperative 8.7±0.8 to 2.0±1.1 postoperatively (p<0.0001). Average preoperative ODI improved significantly from 53.8±6.1 to 22.6±5.1 postoperatively (p<0.0001). Both score were maintained at the final follow-up. The average time to return to previous activity level was 35.7±14.3 days. Average operation time, EBL and hospital stay were 57.6±14.6 minutes, 36.7±13.1 mL and 2.4±0.7 days, respectively. There were total 19 (12.2%) complications and 12 (7.7%) revisions in the series. Overall clinical outcome was excellent, good, fair and poor in 73.1%, 20.5%, 5.1% and 1.3% of cases using modi

Abstract Background Percutaneous endoscopic transforaminal discectomy (PETD) is a widely-used minimally invasive technique in treating lumbar disc herniation (LDH), our aim was to investigate the long-term effect of PETD on clinical outcomes and magnetic resonance imaging (MRI) characteristics of LDH patients.Methods This is a retrospective case series to assess patients who underwent single level PETD from January 2015 to June 2019 with a minimum follow-up of 2 years. Clinical outcomes included numeric rating scale (NRS), Oswestry Disability Index (ODI) and adverse events. Radiographic parameters included sagittal spine geometry, characteristics of protrusion, and degeneration grading of intervertebral disc and facet joint. Sensitivity analysis and risk factor analysis were also performed.Results Thirty-eight patients (43.16 ± 13.32 years; M: F = 20: 18) were assessed. During the follow-up period (33.47±12.53 months), the mean disc height decreased from 10.27 ± 1.92 mm to 8.95 ± 1.74 mm (P=0.000), and lumbar lordosis increased from 31.31 ± 8.63° to 35.07 ± 8.07° (P=0.002). The size of protrusion significantly decreased after PETD (P=0.000). Disc degeneration grading was generally higher at last follow-up compared with baseline (p=0.002). Compared with baseline, significant improvements were observed on NRS and ODI at 3-months follow-up and the last follow-up. On risk factor analysis, facet tropism was correlated with radiographic recurrence of disc herniation (OR=6.00 [95% confidential interval (CI)1.176-30.624], p=0.031).Conclusions This study demonstrates that at long-term follow-up, despite the good clinical results, the PETD resulted in significant aggravation of intervertebral disc degeneration.

Introduction: Conventional discectomy is a common surgical method for treating lumbar disc prolapse. The situation may differ in heavy manual workers who may have more pronounced degenerative spine disease, broad-based disc herniations, and are expected to be exposed postoperatively to the same preoperative manual stress. This study was aimed at comparing the clinical outcomes in patients operated for conventional discectomy versus those operated for TLIF with unilateral spinal fixation. Methodology: Sixty patients underwent surgeries for lumbar disc herniation. They were divided into two groups; the microscopic conventional discectomy group and the fusion (TLIF and unilateral TPF) group. They were operated between 2017 and 2019. Participants were evaluated pre- and postoperatively at 3, 6, 9, and 12 months’ intervals. Pain was scored by Visual Analogue Scale (VAS) for both lower limb and back pain. The clinical outcomes were compared using the Prolo economic and functional rating scale and a new outcome score. Result: The two groups of patients were fairly homogeneous and comparable. Workload exposure to repetitive vibration was the biggest risk for disc prolapse and surgery (28.3%). Fusion group showed better clinical outcomes parameter including better VAS for back pain, better Prolo economic and functional rating scale, and better new clinical outcome score. In comparison, the discectomy group showed significantly higher recurrence rate and reoperation during the follow-up period. During the 12 months’ follow-up visit, when the patients were asked if, under the same circumstances, they would undergo the procedure again, 71.6% of the patients (43 patients) answered affirmatively and this reflects their satisfaction with the results of their surgeries. This satisfaction was reported in 27 patients (90%) in the fusion group and 16 patients (53.4%) in the discectomy group. Conclusion: Heavy manual workers treated with unilateral transforaminal interbody fusion reported less pain and lower disability scores all over the follow-up period. This technique is preferable to conventional discectomy because it reduces back and leg pain while avoiding the possibility of recurrence by heavy duties and maintains stability of the lumbar spine. We proposed a new clinical outcome score to monitor the clinical outcomes of spine surgery in heavy manual workers. It relates the outcomes to the hours of work, sick leaves, and patient satisfaction with surgery. In our group of patients, it showed significant improvement in the fusion group in comparison to the discectomy group.

Abstract Background The area which located at the medial pedicle, posterior vertebral body and ventral hemilamina is defined as the hidden zone. Surgical management of hidden zone lumbar disc herniation (HZLDH) is technically challenging due to its difficult surgical exposure. The conventional interlaminar approach harbors the potential risk of post-surgical instability, while other approaches consist of complicated procedures with a steep learning curve and prolonged operation time. Objective To introduce microscopic extra-laminar sequestrectomy (MELS) technique for treatment of hidden zone lumbar disc herniation and present clinical outcomes. Methods Between Jan 2016 to Jan 2018, twenty one patients (13 males) with HZLDH were enrolled in this study. All patients underwent MELS (19 patients underwent sequestrectomy only, 2 patients underwent an additional inferior discectomy). The nerve root and fragment were visually exposed using MELS. The operation duration, blood loss, intra- and postoperative complications, and recurrences were recorded. The Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the modified MacNab criteria were used to evaluate clinical outcomes. Postoperative stability was evaluated both radiologically and clinically. Results The mean follow-up period was 20.95 ± 2.09 (18–24) months. The mean operation time was 32.43 ± 7.19 min and the mean blood loss was 25.52 ± 5.37 ml. All patients showed complete neurological symptom relief after surgery. The VAS and ODI score were significantly improved at the final follow-up compared to those before operation (7.88 ± 0.70 vs 0.10 ± 0.30, 59.24 ± 10.83 vs 11.29 ± 3.59, respectively, p < 0.05). Seventeen patients (81%) obtained an “excellent” outcome and the remaining four (19%) patients obtained a “good” outcome based the MacNab criteria. One patient suffered reherniation at the same level one year after the initial surgery and underwent a transforaminal endoscopic discectomy. No major complications and postoperative instability were observed. Conclusions Our observation suggest that MELS is safe and effective in the management of HZLDH. Due to its relative simplicity, it comprises a flat surgical learning curve and shorter operation duration, and overall results in reduced disturbance to lumbar stability.

Abstract Background Surgical management of lumbar disc herniation in the hidden zone is technically challenging due to its difficult surgical exposure. The conventional interlaminar approach harbors the potential risk of post-surgical instability, while other approaches consist of complicated procedures with a steep learning curve and prolonged operation time. Objective To introduce a safe and effective technique named microscopic extra-laminar sequestrectomy (MELS) for treatment of hidden zone lumbar disc herniation and present clinical outcomes within a two year follow-up period. Methods Between Jan 2016 to Jan 2018, twenty one patients (13 males) with hidden zone lumbar disc herniation were enrolled in this study. All patients underwent MELS (19 patients underwent sequestrectomy only, 2 patients underwent an additional inferior discectomy). The nerve root and herniated fragment were visually exposed using this extra-laminar approach. The operation duration, blood loss, intra- and postoperative complications, and recurrences were recorded. The Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the modified MacNab criteria were used to evaluate clinical outcomes. Postoperative stability was evaluated both radiologically and clinically. Results The mean follow-up period was 20.95 ± 2.09 months, ranging from 18 to 24 months. The mean operation time was 32.43 ± 7.19 min and the mean blood loss was 25.52 ± 5.37 ml. All patients showed complete neurological symptom relief after surgery.

Lumbar disc herniation (LDH) is a common cause of back and sciatic pain. When clinical treatment fails, surgery may be indicated in selected patients. Although surgery is effective in most cases, some of these patients may have a poor outcome. Different factors may influence these results and poor adaptation at work is one well-known cause of treatment failure. This study examines 350 patients on long-term follow-up after surgery for first-time LDH. The relationship was analyzed between occupation before surgery and outcome (maintenance of lumbar and leg pain, satisfaction with the surgical treatment and return to work). The preoperative occupation (employed in public or private services, autonomous, unemployed, housewife, retired or student) and the exertion at work were analyzed as prognostic factors for different clinical outcomes. Although unemployed people had higher numerical analog scale for lumbar pain and retired patients had a higher leg pain, this difference was not statistically significant. Retired people were significantly less satisfied with the surgical result. Higher exertion at work showed a statistically insignificant higher level of pain and lower degree of satisfaction. The authors conclude that preoperative occupation was not a statistically significant factor in this series of patients.

Abstract Background: Although numerous studies have shown good clinical results of percutaneous endoscopic lumbar discectomy (PELD) for hospitalized patients with lumbar disc herniation (LDH), there are few articles that report on the day surgery patients undergoing PELD.Methods: Atotal of 267 patients with LDH received PELD during day surgery were followed up for at least 3 years. Relevant data and clinical outcomeswere recorded and assessed. Meanwhile, we compared the clinical effects between patients treated by PELD during day surgery and microendoscopic discectomy (MED) for contemporaneous hospitalized patients with LDH (116 patients).Results: Patients treated by PELD had lower blood loss (10.8 ± 4.1 mL, 71.3 ± 23.3 mL,respectively; P < 0.001) and shorter hospital stay ( 22.7 ± 4.2 hours, 48.1 ± 22.6 hours, respectively; P < 0.001 ) compared with patients treated by MED. The visual analogue scale (VAS) for leg and back pain (VAS-L and VAS-B, respectively) and Oswestry disability index (ODI) decreased significantly after PELD than those before the operation at 3 years postoperative, and the postoperative VAS-B in PELD group was significantly decreased from the MED group ( P = 0.001). The complications rate was 9.4% (25/267) in the PELD group and 12.1% (14/116) in the MED group, without significant difference ( P = 0.471). The 1-year postoperative recurrence rate in PELD group ( 5.2%, 14/267) was much higher than that in MED group ( 0.9%, 1/116) ( P = 0.042). The postoperative lumbar lordosis（LL）(34.0 ±10.3 ), and sacral slope（SS) (27.5 ± 5.6) in PELD group improved significantly compared with the values in MED group (26.9 ± 9.8, 23.6 ± 6.8, respectively; all P < 0.001). The disc-height ratio at 3-year follow-up was ( 85.7 ± 6.4) % of the preoperative disc height in PELD group while ( 81.9 ± 7.0) % in MED group，with significant height loss in MED group ( P = 0.014).Conclusions: Day surgery for LDH undergoing PELD has favorable long-term outcomes.
