ObjectivesRecurrent lumbar spine surgery due to disc herniation is a contributor to debilitating pain, disability, and carries a high patient morbidity rate1 We identified risk factors for recurrent lumbar disc herniation post-surgical intervention.DesignRetrospective Cohort Study.SubjectsAll adult lumbar spine revisions for disc herniation performed in the Neurosurgical Department at Ninewells Hospital.MethodsThe number of revisions from 2013 to 2017 for each patient was recorded and two groups were identified. The first group consisted of patients who had one revision and the second group consisted of patients who had recurrent revisions (more than one) Possible factors influencing the likelihood of recurrent revisions were also noted, including age, gender, BMI, operation length, level of surgery, time from primary surgery to revision, smoking and diabetes status.Results140 patients had revision surgeries, of which 87 (62.1%) had one revision while 53 (37.1%) had recurrent operations. Younger patients (p=0.025) and patients with higher BMI (p=0.01) were more likely to have a higher number of revisions. Patients with DM (p=0.015) were associated with a higher likelihood of recurrent revisions. Other factors had little effect on the likelihood of recurrent revisions (p>0.05).ConclusionsIdentifying risk factors that influence the recurrence of lumbar revisions helps improve patient outcome and decrease incidence of revisions.

AimsThe purpose of this study was to investigate the risk of additional surgery in the lumbar spine and to describe long-term changes in patient-reported outcomes after surgery for lumbar disc herniation in adolescents and young adults.Patients and MethodsWe conducted a retrospective study design on prospectively collected data from a national quality register. The 4537 patients were divided into two groups: adolescents (≤ 18 years old, n = 151) and young adults (19 to 39 years old, n = 4386). The risk of additional lumbar spine surgery was surveyed for a mean of 11.4 years (6.0 to 19.3) in all 4537 patients. Long-term patient-reported outcomes were available at a mean of 7.2 years (5.0 to 10.0) in up to 2716 patients and included satisfaction, global assessment for leg and back pain, Oswestry Disability Index, visual analogue scale for leg and back pain, EuroQol five-dimension questionnaire (EQ-5D), and 36-Item Short-Form Health Survey (SF-36) Mental Component Summary and Physical Component Summary scores. Statistical analyses were performed with Cox proportional hazard regression, chi-squared test, McNemar’s test, Welch–Satterthwaite t-test, and Wilcoxon’s signed-rank test.ResultsAny type of additional lumbar spine surgery was seen in 796 patients (18%). Surgery for lumbar disc herniation accounted for more than half of the additional surgeries. The risk of any additional surgery was 0.9 (95% confidence interval (CI) 0.6 to 1.4) and the risk of additional lumbar disc herniation surgery was 1.0 (0.6 to 1.7) in adolescents compared with the young adult group. Both age groups improved their patient-reported outcome data after surgery (all p < 0.001). Changes between short- (mean 1.9 years (1.0 to 2.0)) and long-term follow-up (mean 7.2 years (5.0 to 10.0)) were small.ConclusionThe risk of any additional lumbar spine surgery and additional lumbar disc herniation surgery was similar in adolescents and young adults. All patient-reported outcomes improved from preoperative to the short-term follow-up, while no likely clinically important differences between the short- and long-term follow-up were seen within both groups.

Lower Lumbar Spine

Lumbar disc herniation is one of the common clinical diseases of the lower lumbar spine in orthopedics. The purpose is to remove the herniated disc nucleus pulposus tissue, remove the compressed part of the disease, and relieve symptoms, such as nerve pain. In the past, biomechanics research mostly relied on in vitro measurements, but the complicated internal environment of the human body prevented us from further measurement and research. However, with the development of computer technology, the use of computer CT scanning, software three-dimensional reconstruction, and displacement study three-dimensional spine biomechanics method makes the research of biomechanics into in vitro simulation stage and has gradually become the focus of current research. The postoperative biomechanics was simulated and the comparison model was established at the same time. At the same time, we combined the clinical follow-up data and studied the clinical data for the treatment of postoperative recurrence of lumbar disc herniation. We compared and analyzed the initial operation method and the experimental results and obtained the prevention of recurrence. The results showed that when one inferior articular process was removed, the lumbar spine appeared unstable to rotate to the opposite side; when one inferior articular process was completely removed, the movement of the lumbar spine in all directions was unstable. Better research on the biomechanical properties of the spine will help the diagnosis and treatment of clinical lumbar disc herniation. Therefore, when performing posterior lumbar spine surgery, not only should the exposure of the surgical field and thorough decompression be considered, but also the biomechanical properties of the lumbar spine should be comprehensively evaluated.

Study design: Prospective comparative cohort study. Objectives: The study aims to elucidate the relationship between Modic endplate changes and clinical outcomes after a lumbar microdiscectomy. Methods: Consecutive patients undergoing microdiscectomy for lumbar disc herniation (LDH) were prospectively studied. Pre-operative clinical and radiological parameters were recorded. The pain was assessed by Numeric pain rating scale (NPRS), and functional assessment by Oswestry Disability Index (ODI). Minimal clinically important difference (MCID) in outcome was calculated for both the groups. Complications related to surgery were studied. Follow-up was done at 6 weeks, 3 months, 6 months and 1 year. Mac Nab criteria were used to assess patient satisfaction at 1 year. Results: Out of 309 patients, 86 had Modic changes, and 223 had no Modic changes. Both groups had similar back pain (p-value: 0.07) and functional scores (p-value: 0.85) pre-operatively. Postoperatively patients with Modic changes had poorer back pain and ODI scores in the third month, sixth month and 1 year (p-value: 0.001). However, MCID between the groups were not significant (p-value: 0.18 for back pain and 0.58 for ODI scores). Mac Nab criteria at 1 year were worse in Modic patients (p-value: 0.001). No difference was noted among Modic types in the pre-operative and postoperative pain and functional outcomes. Four patients in Modic group (4.7%) and one patient in the non-Modic group (0.5%) developed postoperative discitis (p-value: 0.009). Conclusions: Preoperative Modic changes in lumbar disc herniation is associated with less favorable back pain, functional scores and patient satisfaction in patients undergoing microdiscectomy.

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.

Percutaneous Transforaminal Endoscopic Discectomy

Abstract Background: In the last decades, endoscopic techniques to treat lumbar disc herniation (LDH) have gained popularity in clinical practice. However, few studies have described the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) in treating adolescent massive LDH. This study aims to evaluate the surgical outcomes of PTED in treating adolescent patients with massive LDH. Methods: Between October 2012 and December 2018, retrospective analysis of 13 adolescent patients with single segment massive LDH at the Department of Spinal Surgery of Affiliated Dongyang Hospital of Wenzhou Medical University. All patients were followed up for at least 12 months (range 12–20 months). The patients’ lower limb pain was evaluated using visual analogue scale (VAS) scores and the Oswestry Disability Index (ODI). Patient satisfaction was evaluated using the MacNab outcome scale. Clinical outcomes were measured preoperatively, at 3 days, 1 months, 3 months, 6 month and 12 months postoperatively. Results: The VAS score for leg pain was 7.08 ±1.12 preoperatively and 3.23±1.01, 3.0 ± 1.01, and 2.62 ± 0.51, and 2.32± 0.48, and 1.46± 0.52, at 3 days, 1 months, 3 months, 6 months and 12 months postoperatively respectively. The ODI scores was 51.51 ±3.08 preoperatively and 21.74±1.15, 14.81 ± 1.50, and 2.78 ± 0.64, at 3 months, 6 months and 12 months postoperatively respectively. These postoperative scores were all significantly different when compared with preoperative scores (P < 0.001). According to the modified MacNab outcome scale, excellent was obtained in 7 patients, good was obtained in 5 patients, and fair was obtained in 1 patient, and 92.31% of these patients had excellent and good outcomes at the final follow-up. There were no complications related to surgery, and no spinal instability was detected. Conclusion: The PTED is an effective and safe surgical method for the treatment of adolescent patients with massive LDH, but high-quality randomized controlled trials are still required to further verify these findings.
