Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

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

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: Pathophysiology01:23

Degenerative Disc Disease ll: Pathophysiology

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:

  • Orthopedics
  • Neurology
  • Radiology

Background:

  • Lumbar disc herniation (LDH) is common in adults aged 25-55, often linked to prolonged sitting or standing with heavy workloads.
  • Severe LDH can cause significant nerve root and spinal cord compression, leading to neurological deficits.

Observation:

  • A 33-year-old male waiter presented with severe LDH causing neurological dysfunction.
  • Initial MRI suggested a differential diagnosis of LDH or an epidural mass; contrast-enhanced MRI confirmed severe LDH.

Findings:

  • Diagnosing large LDH can be difficult as it may present symptoms similar to spinal tumors.
  • The case underscores the importance of advanced imaging for accurate LDH diagnosis.

Implications:

  • This study provides insights into differentiating severe LDH from spinal tumors.
  • It also informs the development of chiropractic treatment strategies for severe LDH cases.
