OBJECTIVE: The incidence of lumbar disc herniation (LDH) is on the rise annually, with an emerging trend of affecting younger age groups. This study aims to investigate the clinical effectiveness of combining Erxian decoction with auricular acupoint pressure therapy in treating LDH. Our objective is to furnish evidence supporting the incorporation of traditional Chinese medicine (TCM) rehabilitation techniques in clinical settings.
METHODS: This randomized controlled trial enrolled 102 patients diagnosed with LDH and allocated them into Control and Intervention groups. The Control group underwent a 2-week rehabilitation regimen, whereas the Intervention group received an augmented treatment comprising Erxian decoction along with auricular acupoint pressure therapy based on the Control group. Main outcome measures included 3 scales - visual analog scale (VAS), Japanese Orthopedic Association (JOA), and Oswestry Disability Index - as well as 3 inflammatory markers: C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). Additionally, pressure pain threshold and pain tolerance threshold values were evaluated. Participants were assessed at baseline, on 14-day, and on 28-day posttreatment.
RESULTS: After 2 weeks of treatment, both the Control and Intervention groups exhibited significant improvements in the VAS, JOA, ODI, CRP, IL-6, TNF-α, pressure pain threshold, and pain tolerance threshold (P < .05). These improvements persisted at the 28-day in the VAS, JOA, and ODI scores (P < .05). On 14-day, the Intervention group showed significantly better outcomes compared to the Control group in terms of the VAS, JOA, ODI, CRP, TNF-α, and pressure pain threshold (P < .05).
CONCLUSIONS: Compared to conventional rehabilitation therapy, the combination of Erxian decoction and auricular acupoint pressure therapy demonstrates clear benefits in alleviating symptoms in patients with LDH. This approach offers fresh perspectives and substantiates evidence for future treatment strategies in managing LDH.

OBJECTIVE: Post-operative pain after video-assisted thoracoscopic surgery is often treated using thoracic epidural analgesics or thoracic paravertebral analgesics. This article describes a case where a thoracic disc herniation is treated with a thoracoscopic microdiscectomy with post-operative thoracic epidural analgesics. The patient developed a bupivacaine pleural effusion which mimicked a hemothorax on computed tomography (CT).
METHODS: The presence of bupivacaine in the pleural effusion was confirmed using a high performance liquid chromatography method.
RESULTS: The patient underwent a re-exploration to relieve the pleural effusion. The patient showed a long-term recovery similar to what can be expected from an uncomplicated thoracoscopic microdiscectomy.
CONCLUSIONS: A pleural effusion may occur when thoracic epidural analgesics are used in patents with a corridor between the pleural cavity and epidural space.

The purpose of the study was a comparative analysis the effectiveness of microsurgical discectomy and minimally invasive transforaminal lumbar interbody fusion in the treatment of disk herniation adjacent to the anomaly of the lumbosacral junction segment in elderly patients. The study included 80 elderly patients (over 60 years old), divided into two groups: the 1st-(n=39) who underwent microsurgical discectomy; the 2nd- patients (n=41) operated on using minimally invasive transforaminal interbody fusion and percutaneous transpedicular stabilization (MI-TLIF). For the comparative analysis, we used gender characteristics (gender, age), constitutional characteristics (BMI), degree of physical status according to ASA, intraoperative parameters of interventions and the specificity of postoperative patient management, clinical data, and the presence of complications. Long-term outcomes were assessed at a minimum follow-up of 3 years. As a result, it was found that the use of MI-TLIF allows achieving better long-term clinical outcomes, fewer major complications in comparison with the microsurgical discectomy technique in the treatment of disc herniation adjacent to the anomaly of the lumbosacral junction segment in elderly patients.
Цель исследования — сравнительный анализ эффективности использования микрохирургической дискэктомии и минимально инвазивного трансфораминального спондилодеза при лечении грыж межпозвонковых дисков смежного с аномалией пояснично-крестцового перехода уровня у пациентов старшей возрастной группы. В исследование были включены 80 пациентов пожилого возраста (старше 60 лет), выделено две группы: 1-я — пациенты (n=39), которым выполняли микрохирургическую дискэктомию; 2-я — пациенты (n=41), прооперированные с использованием минимально инвазивного трансфораминального межтелового спондилодеза, чрескожной транспедикулярной стабилизации (MI-TLIF). Для сравнительного анализа использовали гендерные характеристики (пол, возраст), конституциональные особенности (ИМТ), степень физического статуса по ASA, интраоперационные параметры вмешательств и специфичность послеоперационного ведения пациентов, клинические данные, наличие осложнений. Оценку отдаленных исходов проводили в минимальном катамнезе 3 лет. В результате установлено, что использование MI-TLIF позволяет достичь лучших отдаленных клинических исходов, меньшего числа серьезных осложнений в сравнении с методикой микрохирургической дискэктомии при лечении грыж межпозвонковых дисков смежного с аномалией пояснично-крестцового перехода уровня у пациентов старшей возрастной группы.

An observational study to discover the common conditions affecting the lumbosacral region that may affect lumbosacral position and tension. All the patients, underwent MRI exaamination (magnetic resonance imaging) in the supine position, were examined by the same consultant radiologist. The article was revised by the institutional ethical approval committee. The position of the nerve roots was observed, and the number of nerve roots was calculated anterior to a line passing between the mid-transvers process of L3(third lumbar vertebra). The number of nerve roots ahead of this line was calculated by the radiologist at the level of the right intervertebral foramen and at the left one. This procedure was applied to the normal group, and 5 common pathological diseases were repeated including single-level lumbar disc prolapse, multiple-disc prolapse, multiple bulge, spinal stenosis and spondylolisthesis (at the level of L45 (fourth to fifth lumbar vertebrae) or L5S1 (fifth lumbar to first sacral vertebrae) being outside the study area, i.e., L3). We noticed significant difference in the number of the nerve roots between the cases with herniated discs, spinal stenosis, and spondylolisthesis with the normal group and the significance was in ascending increment in significance being the highest in cases with spondylolisthesis, and even in the groups of other pathologies which are statistically not significant, we noticed that the significance is proportional to the severity of the disease being the least in single level cases (p 0.427), to be more significant on cases with multiple prolapses(p 0.319) to be more in cases with multiple bulges to start to be statistically significant in herniated, higher significance in cases with spinal stenosis to be the highest in cases with spondylolisthesis.

Background and Objectives: The aim of this study is to present our experience in the surgical treatment of calcified thoracic herniated disc disease via a transthoracic approach in the lateral position with the use of intraoperative computed tomography (iCT) and augmented reality (AR). Materials and Methods: All patients who underwent surgery for calcified thoracic herniated disc via a transthoracic transpleural approach at our Department using iCT and microscope-based AR were included in the study. Results: Six consecutive patients (five female, median age 53.2 ± 6.4 years) with calcified herniated thoracic discs (two patients Th 10-11 level, two patients Th 7-8, one patient Th 9-10, one patient Th 11-12) were included in this case series. Indication for surgery included evidence of a calcified thoracic disc on magnet resonance imaging (MRI) and CT with spinal canal stenosis of >50% of diameter, intractable pain, and neurological deficits, as well as MRI-signs of myelopathy. Five patients had paraparesis and ataxia, and one patient had no deficit. All surgeries were performed in the lateral position via a transthoracic transpleural approach (Five from left side). CT for automatic registration was performed following the placement of the reference array, with a high registration accuracy. Microscope-based AR was used, with segmented structures of interest such as vertebral bodies, disc space, herniated disc, and dural sac. Mean operative time was 277.5 ± 156 min. The use of AR improved orientation in the operative field for identification, and tailored the resection of the herniated disc and the identification of the course of dural sac. A control-iCT scan confirmed the complete resection in five patients and incomplete resection of the herniated disc in one patient. In one patient, complications occurred, such as postoperative hematoma, and wound healing deficit occurred. Mean follow-up was 22.9 ± 16.5 months. Five patients improved following surgery, and one patient who had no deficits remained unchanged. Conclusions: Optimal surgical therapy in patients with calcified thoracic disc disease with compression of dural sac and myelopathy was resectioned via a transthoracic transpleural approach. The use of iCT-based registration and microscope-based AR significantly improved orientation in the operative field and facilitated safe resection of these lesions.

OBJECTIVE: Percutaneous endoscopic transforaminal discectomy (PELD) is a new minimally invasive spine surgery for patients with lumbar disc herniation (LDH). Based on the 3-year follow-up data, the effect of PELD on the clinical outcomes of patients with LDH through a retrospective cohort study was analyzed in this article, so as to provide guidance for clinical selection of surgical options.
METHODS: The clinical data of 150 patients with LDH admitted to our hospital from January 2019 to October 2020 were retrospectively analyzed. According to the surgical methods recorded in the medical record system, the patients were divided into the open lumbar microdiscectomy (OLM) group (n = 50) and the PELD group (n = 100). The surgical and postoperative recovery indicators of the two groups were compared after matching. These included incision length, intraoperative blood loss, operation time, postoperative ambulation time and hospital stays, recovery rate, short-term complication rate, Lumbar visual analogue scale (VAS) score, and Oswestry Disability Index (ODI) score.
RESULTS: Compared with the OLM group, the PELD group had shorter incision length, shorter operation time, shorter postoperative ambulation time, shorter hospital stays, less intraoperative blood loss, lower short-term complication rate, lower lumbar pain and dysfunction scores at 3 months, 6 months, and 1 year after operation, higher short-term excellent-and-good recovery rate, and higher quality-of-life scores at 3 years after operation (p < 0.05).
CONCLUSIONS: Compared with OLM, PELD in the treatment of LDH patients can reduce the operation time, blood loss, and length of hospital stays, suggesting a short-term postoperative recovery effect. Compared with OLM, PELD can also reduce the incidence of short-term complications, enhance the effect of pain control and improvement of dysfunction in the medium term, and improve the long-term quality of life.

BACKGROUND: The clinical symptoms of Lumbar Disc Herniation (LDH) can be effectively ameliorated through Lever Positioning Manipulation (LPM), which is closely linked to the brain\'s pain-regulating mechanisms. Magnetic Resonance Imaging (MRI) offers an objective and visual means to study how the brain orchestrates the characteristics of analgesic effects. From the perspective of multimodal MRI, we applied functional MRI (fMRI) and Magnetic Resonance Spectrum (MRS) techniques to comprehensively evaluate the characteristics of the effects of LPM on the brain region of LDH from the aspects of brain structure, brain function and brain metabolism. This multimodal MRI technique provides a biological basis for the clinical application of LPM in LDH.
METHODS: A total of 60 LDH patients and 30 healthy controls, matched by gender, age, and years of education, will be enrolled in this study. The LDH patients will be divided into two groups (Group 1, n = 30; Group 2, n = 30) using a random number table method. Group 1 will receive LPM treatment once every two days, for a total of 12 times over 4 weeks. Group 2 will receive sham LPM treatment during the same period as Group 1. All 30 healthy controls will be divided into Group 3. Multimodal MRI will be performed on Group 1 and Group 2 at three time points (TPs): before LPM (TP1), after one LPM session (TP2), and after a full course of LPM treatment. The healthy controls (Group 3) will not undergo LPM and will be subject to only a single multimodal MRI scan. Participants in both Group 1 and Group 2 will be required to complete clinical questionnaires. These assessments will focus on pain intensity and functional disorders, using the Visual Analog Scale (VAS) and the Japanese Orthopaedic Association (JOA) scoring systems, respectively.
CONCLUSIONS: The purpose of this study is to investigate the multimodal brain response characteristics of LDH patients after treatment with LPM, with the goal of providing a biological basis for clinical applications.

UNASSIGNED: Intervertebral disc herniation, defined as the protrusion or extrusion of the disc mass outside the disc space, is common and easy to diagnose on conventional Magnetic Resonance imaging (MRI) or Computed Tomography (CT) scans. However, the sequestrated disc fragments are challenging to detect, and intervertebral disc mass displacement into the dural sac, which can lead to serious neurological problems such as Cauda equina syndrome (CES). The sequestrated disc fragments do not have specific clinical or radiological characteristics that can differentiate an atypical disc mass from a tumor, making the diagnosis difficult preoperatively. Herein, we describe the use of Sampling Perfection with Application Optimized Contrast using different flip angle Evolution in Magnetic Resonance Imaging (3D SPACE MRI) in the diagnosis of the intervertebral disc fragment that mimicked a tumor.
UNASSIGNED: In this study, we report two cases of sequestered lumbar disc herniation. The first case was a 37-year-old patient with a 2-year history of intermittent left lower limb pain that aggravates with exercise and is relieved at rest, while the second case was a 42-year-old patient with a history of 40 days of numbness and pain in the left lower limb.
UNASSIGNED: 3D SPACE MRI is a beneficial diagnostic imaging tool for discriminating between disc mass that mimics a tumor and a tumor before surgery. If the disc fragment mimicking a tumor can be identified before the operation, open surgical treatment won\'t be necessary for all patients.

OBJECTIVE: To campare biomechanical effects of different postural compression techniques on three-dimensional model of lumbar disc herniation (LDH) by finite element analysis.
METHODS: Lumbar CT image of a 48-year-old female patient with LDH (heighted 163 cm, weighted 53 kg) was collected. Mimics 20.0, Geomagic Studio, Solidwords and other software were used to establish three-dimensional finite element model of LDH on L4,5 segments. Compression techniques under horizontal position, 30° forward bending and 10° backward extension were simulated respectively. After applying the pressure, the effects of compression techniques under different positions on stress, strain and displacement of various tissues of intervertebral disc and nerve root were observed.
RESULTS: L4, 5 segment finite element model was successfully established, and the model was validated. When compression manipulation was performed on the horizontal position, 30° flexion and 10° extension, the annular stress were 0.732, 5.929, 1.286 MPa, the nucleus pulposus stress were 0.190, 1.527, 0.295 MPa, and the annular strain were 0.097, 0.922 and 0.424, the strain sizes of nucleus pulposus were 0.153, 1.222 and 0.282, respectively. The overall displacement distance of intervertebral disc on Y direction were -3.707, -18.990, -4.171 mm, and displacement distance of nerve root on Y direction were +7.836, +5.341, +3.859 mm, respectively. The relative displacement distances of nerve root and intervertebral disc on Y direction were 11.543, 24.331 and 8.030 mm, respectively.
CONCLUSIONS: Compression manipulation could make herniated intervertebral disc produce contraction and retraction trend, by increasing the distance between herniated intervertebral disc and nerve root, to reduce symptoms of nerve compression, to achieve purpose of treatment for patients with LDH, in which the compression manipulation is more effective when the forward flexion is 30°.
