Spinal Stenosis: Causes and Symptoms

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Spinal stenosis is a condition characterized by the narrowing of the spinal canal, which can lead to compression of the neural structures. It is one of the most common causes of low back and leg pain, particularly in older adults. This article explores the causes and symptoms of spinal stenosis, drawing on recent research findings.

Causes of Spinal Stenosis

Degenerative Changes

• The most common cause of spinal stenosis is degenerative changes in the spine, which include the thickening of ligaments, formation of bone spurs, and degeneration of intervertebral discs. These changes can lead to the narrowing of the spinal canal and compression of the spinal cord and nerve roots1 2 3.

Disc Herniation

• Herniated discs can also contribute to spinal stenosis by protruding into the spinal canal and exerting pressure on the neural structures. This is often seen in conjunction with other degenerative changes1.

Spondylolisthesis

• Degenerative spondylolisthesis, where one vertebra slips over the one below it, can further narrow the spinal canal and exacerbate symptoms of spinal stenosis1.

Symptoms of Spinal Stenosis

Pain

• Pain is a primary symptom of spinal stenosis and can manifest in the lower back (lumbar region) or neck (cervical region). The pain may radiate to the legs or arms, depending on the location of the stenosis1 2 3.

Neurogenic Claudication

• Patients often experience neurogenic claudication, characterized by pain, tingling, or numbness in the legs that worsens with walking or standing and improves with sitting or bending forward. This symptom is particularly common in lumbar spinal stenosis2 4.

Reduced Function and Mobility

• Spinal stenosis can lead to significant disability, reducing a patient’s ability to perform daily activities and impacting their quality of life. This reduction in function is often measured using tools like the Oswestry Disability Index (ODI)2 3.

Other Neurological Symptoms

• In severe cases, spinal stenosis can cause more pronounced neurological symptoms, including weakness, loss of balance, and bladder or bowel dysfunction. These symptoms indicate significant compression of the spinal cord or nerve roots and may require urgent medical attention2 4.

Conclusion

Spinal stenosis is a prevalent condition, especially among older adults, caused primarily by degenerative changes in the spine. It leads to a range of symptoms, including pain, neurogenic claudication, and reduced function. Understanding the causes and symptoms is crucial for effective management and treatment of this condition.
