Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

45
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...

Degenerative Disc Disease I: Introduction

29
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology

36
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Radiology

Background:

  • Intradural disc herniation (IDH) is an uncommon spinal condition.
  • Diagnosis is challenging, often requiring intraoperative confirmation despite advanced imaging.

Purpose of the Study:

  • To present a case of intradural disc herniation.
  • To review the incidence, pathogenesis, clinical presentation, diagnostic modalities, and management of IDH.

Main Methods:

  • Case report presentation.
  • Literature review on intradural disc herniation.

Main Results:

  • Intradural disc herniation is a rare complication.
  • Diagnosis often relies on intraoperative findings.

Conclusions:

  • Intradural disc herniation requires a high index of suspicion.
  • Comprehensive review aids in diagnosis and management.
