Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

44
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

34
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...

Summary

Cervical disc herniation rarely causes contralateral radiculopathy, but this case demonstrates its possibility. Surgical intervention resolved symptoms in a patient with right-sided herniation causing left-sided pain.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Neurology

Background:

  • Cervical disc herniation typically causes ipsilateral symptoms.
  • Contralateral radiculopathy due to cervical disc herniation is exceptionally rare.

Observation:

  • A 53-year-old man presented with left upper extremity pain and numbness.
  • Physical examination revealed left-sided sensory deficits and a positive Spurling maneuver.
  • Imaging confirmed right-sided C4-C5 and C5-C6 disc herniation.

Findings:

  • Despite conservative treatment, symptoms persisted.
  • Anterior cervical discectomy and fusion at C4-C5 and C5-C6 led to immediate symptom resolution.
  • The patient remained pain-free during a 2-year follow-up.

Implications:

  • This case highlights that cervical disc herniation can exceptionally manifest with contralateral radiculopathy.
  • Careful diagnosis and exclusion of other conditions are crucial when considering surgery for such rare presentations.
  • Surgical treatment may be effective for cervical disc herniation causing contralateral symptoms when conservative management fails.
