Lateral Canal Stenosis

Lateral canal stenosis is a term referring to the narrowing of the sides of the spinal canal. It also can refer to a reduction of the spaces through which spinal nerve roots exit the spinal cord on either side of the vertebrae. Neither of these conditions produces symptoms unless the spinal cord itself or adjacent nerve roots become irritated, or compressed. When this happens, it can produce symptoms such as localized pain, radiating pain, tingling, numbness or muscle weakness in the areas of the body innervated by the affected nerves.

Causes of Lateral Canal Stenosis

Spinal stenosis typically is a result of the natural aging process, which takes a toll on the components of the spinal anatomy. Degenerative disc disease can lead to herniated or bulging discs. Spinal arthritis can produce bone spurs. When these conditions develop along the sides of the spinal canal, as opposed to the middle, it is known as lateral canal stenosis. The condition, which can occur at any level of the spine, also can be referred to as:

• Lateral recess stenosis
• Subarticular stenosis
• Lateral gutter stenosis
• Subpedicular stenosis
• Foraminal canal stenosis
• Intervertebral foramen stenosis

Treating Lateral Canal Stenosis

Conservative treatments such as pain medication, physical therapy, exercise, stretching and others generally are effective for managing symptoms associated with spinal stenosis. However, if chronic symptoms persist after weeks or months of conservative treatment, surgery might become an option. If so, contact Laser Spine Institute to learn how our orthopedic specialists can help you rediscover your life without back and neck pain.
