What is spinal stenosis?

Spinal stenosis refers to the narrowing of the bony canals that contain the spinal cord and nerve roots. This condition occurs when the spaces within the spine become constricted, which can lead to pressure on the spinal cord and surrounding nerves. The narrowing may be due to a variety of factors, including degenerative changes such as disc herniation, bone spurs, or thickening of the surrounding ligaments. Symptoms often include pain, weakness, or numbness in the legs and back, particularly when standing or walking, as the narrowed spaces can compress the neural structures.

Understanding spinal stenosis is crucial, especially in relation to imaging and diagnostic procedures in CT and MRI, as these modalities can effectively visualize the anatomical changes contributing to the condition. Recognition of spinal stenosis is important for forming an appropriate treatment plan, which may include physical therapy, medications, or possibly surgical intervention to relieve the pressure on the spinal cord and nerves.
