Disc herniation L5-S1

OBJECTIVE: Percutaneous endoscopic lumbar discectomy (PELD) is a safe and effective minimally invasive surgery for treating lumbar disc herniation (LDH); however, the comparative clinical efficacy of percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID) in treating L5-S1 LDH remains unclear. This study compared the clinical advantages of PEID and PETD for treating L5-S1 LDH. METHODS: This was a single-centre retrospective study analysing clinical data from 120 patients with L5-S1 LDH between February 2016 and May 2020...

OBJECTIVE: Isthmic spondylolisthesis (IS) is distinguished by a congenital defect or acquired fracture of the pars interarticularis. Numerous studies on L5 low-grade IS have been carried out; however, there is a paucity of data regarding the condition of L5 IS concomitant with L4/5 disc herniation. This study aimed to identify the incidence rate and to illustrate the possible risk factors for L4/5 disc herniation in L5 low-grade IS patients. METHODS: A total of 268 consecutive patients diagnosed as L5/S1 low-grade IS between May 2017 and May 2022 were retrospectively enrolled in this study...

BACKGROUND: Lumbar disc herniation is one of the important and common causes of low back pain. There are various modifiable and non-modifiable risk factors for the development of lumbar disc herniation. Any change in the orientation or asymmetry of the facet joint i.e. facet tropism may lead to abnormal shearing stress on the intervertebral disc and may lead to development of disc herniation. METHODS: This is a cross-sectional observational study of 46 patients aged 18-40 years with clinical features of Prolapsed Intervertebral Disc and Magnetic Resonance Imaging evidence of single level prolapsed disc who presented to Tribhuvan University Teaching Hospital from December 2019 to June 2021...

OBJECTIVE: A preliminary report from a single institution, noninferiority, prospective randomized controlled trial is conducted to determine the effectiveness of interlaminar endoscopic lumbar discectomy (IELD) versus microscopic lumbar discectomy (MLD) for the treatment of L5-S1 lumbar disc herniation (LDH). METHODS: This prospective, noncrossover, randomized controlled trials was conducted at a single neurosurgical center. Patients with symptomatic radiculopathy or intermittent neurogenic claudication caused by LDH were enrolled from July 2016 to July 2021...

Lumbar disc herniation (LDH) is a clinically common degenerative disease of the spine, and spinal-pelvic sagittal balance and paravertebral muscle degeneration have been a research focus in recent years. To explore the relationship between the degeneration of paravertebral muscle and the changes in the spinal-pelvic sagittal parameters in LDH patients, 105 LDH patients (experimental group) and 63 healthy volunteers (control group) hospitalized in Ordos Central Hospital from January 2020 and January 2023 were included as study subjects...

BACKGROUND: Common severe back pain due to disc herniation is rare in the paediatric population which involves children under eighteen years of age. Paediatric lumbar disc herniation (LDH) cannot be considered the same disease as in adults, as it has potentially different natural and clinical backgrounds. The treatment of pediatric LDH is the other particularity of this condition. Indeed, in children, delaying surgery for a conservative treatment is justified. We report 3 cases treated in 8 years...

Trp3 allele in COL9A3 gene has been widely studied in populations with intervertebral disc disease. We identified a novel pathogenic variant in COL9A3 gene in a pedigree with multiple lumbar disc herniation (LDH). The proband was a 14-year-old boy who developed LDH at the L4/5 and L5/S1 spinal segments. His father, paternal aunt and grandfather were diagnosed with LDH at an age of 35, 30 and 23, respectively. By applying whole exome sequencing, a heterozygous missense variant (c.1150C > T, p...

Guillain-Barré syndrome (GBS), an immune-mediated disease of the peripheral nervous system, is mainly characterized by rapidly progressive ascending weakness of the limbs with reduced or absent deep tendon reflexes. The exact cause of GBS is unknown, but it often occurs after a gastrointestinal or respiratory infection. The present study represents a case of GBS in which multiple antecedent antigenic stimuli may have contributed to the development of GBS. The patient, a 28-year-old immunocompetent man with no significant medical history, presented to the emergency department (ED) with acute ascending flaccid paralysis that persisted for a few days...

[Purpose] The purpose of this study was to clarify the preliminary reference values for the lumbar spine range of motion associated with lateral bending exercises by gender and age group. [Methods] Subjects were 82 volunteers without low back pain, including five males and five females in each age group from 16-19 to 80-89 years. All subjects underwent radiographs of the lumbar spine with lateral flexion; the range of lateral flexion of the vertebrae from T12 to the sacrum (ROLB) was measured twice by three observers...

BACKGROUND: No classification system exists for aiding the selection of surgical approaches in L5-S1 disc herniation when undergoing percutaneous endoscopic lumbar discectomy (PELD). We aimed to identify radiographic subtypes to aid the selection of percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID) in patients with L5-S1 disc herniation via unsupervised hierarchical clustering analysis. METHODS: In this retrospective case-control study, we gathered 296 anteroposterior and lateral lumbar spine radiographs (dataset 1) from Tianjin Hospital between January 2016 and October 2021 for clustering analyses...

OBJECTIVE: To determine the diagnostic value of axial T1-weighted imaging for patients suffering from lower back pain. MATERIALS AND METHODS: In this retrospective study, 100 consecutive lumbar spine MRIs obtained in patients with chronic low back pain were reviewed in two sessions: First, readers viewed core sequences (sagittal T1-weighted, STIR and T2-weighted, and axial T2-weighted) with axial T1-weighted sequences, and second, readers viewed cores sequences alone...

BACKGROUND: Percutaneous transforaminal endoscopic discectomy (PTED) has become popular over the years due to its safety and low invasiveness. This surgery can be performed with different anesthesia techniques; however, the extent to which the surgeon and patient are satisfied with the analgesia is debatable. OBJECTIVES: This study investigated the efficiency of the S1 transforaminal epidural block. METHODS: This retrospective study was conducted on 60 patients with L4 - L5 lumbar disc herniation who underwent PTED under the S1 transforaminal epidural block...

INTRODUCTION: Traumatic lumbar disc herniation (TLDH) without fracture in the in-situ motion segment is a rare occurrence compared with degenerative herniation. RESEARCH QUESTION: This study provides a systematic discussion of various aspects related to the diagnosis of TLDH. MATERIAL AND METHODS: This review includes 12 cases of TLDH with MR-images since 2009 published in the PubMed and one adjunct illustration.

Lumbar disc herniation (LDH) is the most common spinal disorder among which disc sequestration is a severe type where the herniated disc fragment migrates and is completely separated from the parent disc. A 46-year-old female patient with severe lower back pain radiating to right lower limb, disability, and numbness in the affected extremity came to Panchakarma O.P.D of our hospital. She was a chronic case of disc sequestration where her symptoms were severely aggravated after a sudden jolt felt on her lower back while traveling on a motorcycle...

PURPOSE: To study the distribution of lumbar Modic changes (MC) in low back pain patients, and to explore the relationship between Modic changes and age, gender, segment and lumbar degeneration diseases (disc degeneration, spinal stenosis, lumbar spondylolisthesis). PATIENTS AND METHODS: Modic changes were counted and analysed in 500 randomly selected patients who visited the outpatient clinic for lumbar spine MRI for low back pain from 2019 to 2022. The relationship between Modic changes and bulging disc, protrusion, extrusion, sequestration, Schmorl's node, spinal stenosis, and lumbar spondylolisthesis was studied...

INTRODUCTION: This study aimed to compare early efficacy of UBED and PEID in the treatment of L5/S1 IDH. MATERIAL AND METHODS: Forty-two patients who underwent surgical treatment for L5/S1 IDH were divided into two groups: UBED and PEID. Operation time, complications, VAS/ODI score were recorded.

Letter: We have read the recent article published by Zhang et al titled "The Efficacy and Safety of Topical Saline Irrigation with Tranexamic Acid on Perioperative Blood Loss in Patients Treated with Percutaneous Endoscopic Interlaminar Diskectomy: A Retrospective Study". In this retrospective study, authors performed interlaminar endoscopic lumbar discectomy (IELD) for L5-S1 disc herniations, categorizing patients into two groups. One group underwent IELD with saline irrigation fluid containing 0.33 gm of tranexamic acid (TXA) per 1L of saline, while the other group received only saline irrigation fluid...

PURPOSE: Degenerative spinal conditions, including disc degeneration (DD), Schmorl nodes (SN), and endplate signal changes (ESC), are pervasive age-associated phenomena that critically affect spinal health. Despite their prevalence, a comprehensive exploration of their distribution and correlations is lacking. This study examined the prevalence, distribution, and correlation of DD, SN, and ESC across the entire spine in a population-based cohort. METHODS: The Wakayama Spine Study included 975 participants (324 men, mean age 67...
