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:

  • Orthopedics
  • Trauma Surgery
  • Radiology

Background:

  • Spinal trauma can affect various vertebral structures, including intervertebral discs.
  • Intervertebral disc injuries are uncommon in spinal trauma, typically presenting as herniation and rarely in isolation.

Observation:

  • A rare case of traumatic discal fracture occurred in a woman after high-velocity trauma.
  • Imaging studies included full-body computed tomography and lumbar magnetic resonance imaging.

Findings:

  • The patient presented with a lumbar discal fracture.
  • Associated injuries included adjacent bony fractures and a presacral hematoma.
  • Ligamentous injuries were also identified in conjunction with the discal fracture.

Implications:

  • This case underscores the possibility of direct discal fractures in severe spinal trauma.
  • Highlights the importance of comprehensive imaging in evaluating high-velocity spinal injuries.
  • Contributes to understanding rare patterns of injury to the intervertebral disc in trauma
