Which spinal condition involves compression of spinal nerves?

Foraminal stenosis occurs when the foramina, the openings in the vertebrae through which nerve roots exit the spinal column, become narrowed. This narrowing can lead to compression of the spinal nerves as they exit the spinal column, resulting in pain, numbness, or weakness in areas served by the affected nerves. The condition may stem from various factors, including age-related changes, disc degeneration, or other spinal pathologies.

While herniated discs and osteoarthritis can also lead to nerve compression, foraminal stenosis specifically pertains to the narrowing of the foramina themselves. Scoliosis is primarily characterized by lateral curvature of the spine and doesn't inherently involve direct nerve compression, making foraminal stenosis the most accurate choice regarding spinal nerve compression.
