Abstract

Spinal stenosis refers to the abnormal narrowing of the spinal canal or nerve root foramina. The diagnosis is primarily based on a combination of clinical signs and symptoms with concomitant pathoanatomical findings on imaging studies. Spinal stenosis can be secondary to the causes of degenerative, congenital, and acquired etiologies. Degenerative causes, such as degenerative disc disease or ligamentum flavum (LF) hypertrophy, are the most common and increase in frequency with advancing age. Anatomic variations of spinal vertebrae at various levels also contribute to varying causes of stenosis. Though variable, the clinical presentation of spinal stenosis is typically that of the insidious onset of back pain and/or radiculopathy with other neurologic symptoms such as dysesthesias, paresthesias, numbness, and motor weakness with or without neurogenic claudication. This chapter will cover the most common etiologies of spinal stenosis with particular attention to unique characteristics at the cervical, thoracic, and lumbar spinal levels.
