What it is
Cervical spinal stenosis refers to narrowing of the spinal canal in the neck. Unlike a focal disc herniation, stenosis typically results from a combination of changes accumulating over years: disc height loss, osteophyte (bone spur) formation, ligament thickening (particularly the ligamentum flavum), and facet joint hypertrophy. The result is a canal that is too small for the structures it contains.
Stenosis can compress nerve roots (producing radiculopathy — arm pain and weakness), the spinal cord (producing myelopathy — gait problems, hand dysfunction), or both simultaneously.
Congenital versus degenerative stenosis
Some people are born with a naturally narrow cervical canal — congenital stenosis. These individuals are more vulnerable to developing cord compression from even modest degenerative changes. Athletes with congenital cervical stenosis face specific considerations around return to contact sports.
Treatment
Mild cervical stenosis without myelopathy or significant radiculopathy can often be managed conservatively. Moderate-to-severe stenosis with cord compression warrants surgical discussion, as the natural history of cervical myelopathy is progressive neurological decline.
The surgical approach — anterior (ACDF, corpectomy) versus posterior (laminoplasty, laminectomy with fusion) — depends on the distribution and location of compression, the degree of lordosis, and the number of levels involved. Both approaches are well-established; the choice is individualized.
