Introduction: Traumatic lumbar disc herniation (TLDH) without fracture in the 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. The cases were categorized into two groups for a comprehensive analysis, TLDH with or without segment fracture. Additionally, we reported a case of a 43-year-old female patient with a recent stenosing TLDH at L5/S1, accompanied by a large sequestration (disc herniation stage-4, and Michigan State University Classification: MSU 3-AB) and an endplate compression fracture at L2 (AO A1).
Results: Isolated traumatic lumbar disc herniation is possible, but it is required exclude cases with fractures in the motion segment.
Discussion And Conclusion: Trauma with related injury mechanisms is the highest priority for the diagnosis of TLDH. Low-grade disc degeneration without significant instability could be accepted for diagnosing TLDH. A TLDH on MR images might show a slightly lower T2-signal compared to the CSF and a homogeneous T1-signal like the spinal cord, as well as a similar STIR-signal of the sequestration and CSF. If necessary, a histological examination could be performed to evaluate the degenerative changes in the injured disc, especially to assist the evaluation due to legal reasons.

A comparative study of two full-endoscopic foraminoplasty techniques for lumbar disc herniation.

Objective: This study aimed to compare the use of the endoscopic drill (ED) with the extra-endoscopic trephine (EET) in treating lumbar disc herniations with regard to efficiency, safety, and clinical outcomes.
Methods: From January 2022 and June 2023, 136 patients who had the single-level LDH and received the transforaminal endoscopic surgery were divided into two groups according to the foraminoplasty technique: the EET group (n = 69) and the ED group (n = 67). Surgery-related parameters, complications, Visual Analogue Scale (VAS, 0-10), and Oswestry Disability Index (ODI, 0-100%) were assessed and compared among two groups.
Transforaminal lumbar epidural injection of dexmedetomidine versus magnesium sulfate combined with dexamethasone for lower limb radicular pain management: a randomized, clinical trial.

Background: Epidural steroid injections are frequently used to treat chronic radicular pain of a discogenic origin; however, their efficacy remains limited. Magnesium sulfate and dexmedetomidine are emerging adjuvants with the potential to enhance the effectiveness and prolong the therapeutic duration of steroid injections.
Methods: In this randomized, double-blind study, 90 patients with unilateral lower limb radiculopathy due to lumbar disc prolapse who did not respond to conservative treatment for 12 weeks were assigned to three groups.

Lumbar disc herniation (LDH) is a common spinal disease. In recent years, an increasing number of observational studies have reported the impact of inflammatory factors on LDH. By conducting Mendelian randomization (MR) analysis on 91 inflammatory factors, it is possible to reveal their causal relationship with LDH, providing new insights for prevention and treatment strategies.

With a prevalence of over 90% in people over 50, intervertebral disc degeneration (IVDD) is a major health concern. This weakening of the intervertebral discs can lead to herniation, where the nucleus pulpus (NP) leaks through the surrounding Annulus Fibrosus (AF). Considering the limited self-healing capacity of AF tissue, an implant is needed to restore its architecture and function.

Aim: The aim of this study was to investigate patient-reported outcomes (PROs) following lumbar discectomy on patients with lateral lumbar disc herniation (LDH) compared to patients with paramedian LDH.
Background: Surgery for disc herniation is one of the most common procedures of the lumbar spine. LDHs can be divided into median, paramedian, foraminal and extraforaminal types based on the anatomical site of the lesion.
