Spinal Cord: Cross-sectional Anatomy

5.7K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

40
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...

Area of Science:

  • Pediatric Orthopedics
  • Spinal Surgery
  • Biomedical Engineering

Background:

  • Growing rod techniques are common for early-onset scoliosis but have high complication rates, especially in patients with neuromuscular conditions and osteoporotic bone.
  • Traditional interventions often require iterative procedures and eventual vertebral fusion, impacting long-term spinal growth and function.

Purpose of the Study:

  • To review the literature on minimally invasive bipolar fixation as a fusionless alternative for early-onset scoliosis.
  • To evaluate its efficacy, stability, and potential to replace traditional growing rod techniques and vertebral arthrodesis.

Main Methods:

  • Literature review of studies on minimally invasive bipolar fixation for early-onset scoliosis.
  • Analysis of published data regarding technique stability, complication rates, and long-term outcomes.

Main Results:

  • Minimally invasive bipolar fixation demonstrates greater stability compared to traditional growing rods.
  • The technique avoids the need for vertebral arthrodesis, offering progressive spinal stiffening and preserving growth.
  • Published long-term follow-up confirms its effectiveness, particularly in complex scoliosis cases.

Conclusions:

  • Minimally invasive bipolar fixation is a viable, less aggressive alternative to vertebral arthrodesis for early-onset scoliosis.
  • Recommended for children under 10, it preserves spinal growth and may reduce complications and costs, especially with self-expanding rod technology.
