Central Canal Stenosis Definition

Central canal stenosis is the narrowing, or constriction, of the spinal canal. Spinal stenosis can occur at any point along the spine, but is most common in the lumbar (lower back) region. This is due to normal wear and tear, exacerbated by the relative flexibility of the lumbar spine and years of supporting most of the weight of the upper body.

Symptoms of Central Canal Stenosis

Someone with spinal stenosis might never know they have it, because not every case produces symptoms. However, when the spinal canal is narrowed because of excess tissue, bone matter or disc material, the spinal cord becomes vulnerable to irritation. This irritation can lead to localized pain, or pain that travels from the spot of the irritation to another part of the body. It also can produce a tingling feeling in the extremities, as well as the loss of sensation (numbness) and muscle weakness.

Causes of Spinal Stenosis

Most people who suffer from central canal stenosis can pinpoint a degenerative condition, such as osteoarthritis, as the underlying cause. The degeneration of intervertebral discs, a natural result of aging, also can cause conditions that produce spinal stenosis. These conditions include:

• Bulging disc
• Herniated disc
• Bone spurs
• Spondylolisthesis
• Traumatic spine injury
• Enlarged or calcified spinal ligaments
• A congenital spine condition

Treatments for Central Canal Stenosis

Depending on the severity of the stenosis, most patients can manage the symptoms with a combination of conservative treatment that includes pain medicine, exercise, a brief period of rest or physical therapy. If chronic pain persists after an attempt at conservative pain management fails, a doctor might suggest surgery as an option. Rather than settle for the long hospital stay and lengthy recuperation associated with traditional open back surgery, tens of thousands have discovered relief through the minimally invasive, outpatient procedures performed at Laser Spine Institute.
