Source: Wang, L., et.al. Full-Endoscopic Isolation Zone Technique for the Treatment of Lumbar Disc Herniation. J. Vis. Exp.(2023)This video demonstrates a minimally invasive endoscopic procedure to treat lumbar disc herniation by removing the protruded nucleus pulposus and ruptured annulus fibrosus. The technique decompresses the affected nerve root, alleviates pain, and restores nerve function through targeted tissue resection and radiofrequency modulation.

Here, we present a protocol for the "isolation zone" technique in the treatment of lumbar disc herniation (LDH) under full-endoscopic spine surgery (FESS), including intervertebral foramen formation, targeted catheterization, nucleus pulposus resection, and annulus fibrosus formation, which together completely block the pain from the nerve conduction pathway.

Herniated Intervertebral Disc l: Introduction

2026
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Lateral fluid percussion (LFP), an established model of traumatic brain injury in mice, is demonstrated. LFP fulfills three major criteria for animal models: validity, reliability and clinical relevance. The procedure, consisting of surgical craniotomy, fixation of hub followed by induction of injury, resulting in focal and diffuse injuries, is described.

Here we present a protocol of a novel outside-in technique of transforaminal endoscopic discectomy for lumbar disc herniations. The technical aspects of the technique, the wide indications of use, and the results of the treatment in 184 patients are described in detail.
FAQs
Pressure rises when the skull’s contents expand, and the resulting force drives tissue toward spaces that cannot enlarge. Brain partitions and openings, including the tentorial notch and foramen magnum, create fixed pathways for displacement. As tissue moves through these boundaries, it can compress nearby brainstem regions, blood vessels, and cranial nerves, converting pressure elevation into progressive neurological injury.
Swelling, bleeding, tumors, and blocked cerebrospinal fluid are identified causes of the pressure increase that precedes brain herniation. Although these problems differ in origin, each can expand or obstruct intracranial contents enough to disturb normal compartmental relationships. Their shared significance is the development of force capable of shifting tissue and compressing critical structures.
Compression of the brainstem can disrupt functions reflected in consciousness and breathing, while pressure on blood vessels can impair blood flow to brain tissue. Cranial nerve compression may alter pupil responses. These effects show why the danger extends beyond tissue displacement itself: herniation can interfere simultaneously with neurological control, vascular supply, and observable clinical responses.
Deterioration in consciousness, breathing, or pupil responses may signal that pressure is affecting vital neural structures. These findings are important because they can reflect brainstem or cranial nerve compression rather than a minor change in intracranial conditions. In neurology and emergency medicine, recognizing such changes supports rapid assessment of a potentially life-threatening progression.
Imaging helps evaluate intracranial abnormalities and the displacement associated with pressure-related deterioration, while monitoring tracks neurological and pressure-related changes over time. The overview identifies both as important components of managing this emergency. Together, they help clinicians recognize worsening compression, assess the consequences of swelling or bleeding, and guide urgent treatment decisions.
Brain herniation links anatomy, intracranial pressure, and neurological function in a single pathological process. Studying it shows how rigid compartments can turn swelling, bleeding, tumors, or cerebrospinal fluid blockage into compression of essential structures. This biological context supports rapid recognition, neurological assessment, imaging, monitoring, and urgent treatment when consciousness, breathing, or pupil responses deteriorate.
