Central Canal Stenosis

In general, there are two kinds of stenosis: central canal stenosis and vertebral foraminal stenosis. While both conditions describe the gradual narrowing of a foramen – or canal – in the spinal column, central canal stenosis specifically refers to the narrowing of the central spinal canal that surrounds the spinal cord. Over time, this narrowing, or stenosis, can lead to the compression of the spinal cord and a number of pain-related symptoms.

Cervical Spine Anatomy

In a normal spine, the bones of the vertebrae form a sheath around the spinal nerves, effectively protecting them from damage on a regular basis. In addition, the spinal column is also comprised of cartilage, discs, and other tissues to allow the back and neck to move comfortably. Central canal stenosis occurs when a herniated disc, inflamed tissue, bone spur, or other source, takes up space in the spinal canal and impinges on nerves, leading to symptoms like back or neck pain, muscle weakness or stiffness, numbness and tingling.

Spinal Stenosis Causes

Some of the most common ways to develop central canal stenosis include:

• Getting older – unfortunately, a degree of spine deterioration is to be expected as we age. This explains our gradual loss of flexibility and increased aches and pains in the back and neck.
• Traumatic injury – injuring your back or neck can lead to facet joint irritation, herniated discs, and other problems along the spine that can lead to stenosis.
• Smoking – a lifetime of smoking leads to decreased bone density, increases the chance of injury, and can speed the onset of stenosis.
• Improper stretching or lifting – like traumatic injury, not stretching properly before a workout, or straining your back in other ways, can lead to back problems.
• Poor posture – practicing poor posture puts unnecessary strain on your spine and can exacerbate stenosis.
• Obesity – carrying excess body fat also puts needless strain on the spine and can lead to significant back and neck problems.
