Cervical Spinal Canal Stenosis refers to the narrowing of the spinal canal in the cervical (neck) region of the spine. The spinal canal is a bony tunnel that encloses and protects the spinal cord as it travels through the spine. When this canal becomes narrower than normal, it can lead to compression of the spinal cord and nerve roots. Here’s a more detailed description:

1. Causes:

   • Degenerative Changes: The most common cause of cervical spinal canal stenosis is the natural aging process, which can lead to degeneration of the spine, including the intervertebral discs and facet joints.
   • Herniated Discs: Discs between the vertebrae may bulge or herniate, contributing to narrowing of the spinal canal.
   • Bone Spurs: Overgrowth of bone, known as bone spurs or osteophytes, can occur in response to degeneration, contributing to stenosis.
   • Congenital Factors: Some individuals may have a genetic predisposition to narrower spinal canals.

2. Symptoms:

   • Neck Pain: Pain or discomfort in the neck may be present, especially in the affected area.
   • Radiating Arm Pain: Compression of nerve roots in the cervical spine can cause pain that radiates into the arms.
