Lumbar Spinal Stenosis and Foraminal Stenosis

Like cervical stenosis, lumbar spinal stenosis is frequently precipitated by disc degeneration with subsequent marginal osteophytosis of the vertebral body ends, hypertrophic degeneration of the facet joints, and bulging of the ligamenta flava. Lumbar stenosis may be lateral, central, or combined. The lower lumbar vertebrae normally have shorter pedicles that cause the superior articular processes […]

Cervical Spinal Stenosis and Foraminal Stenosis

Cervical spinal stenosis can be congenital or acquired. In the less common congenital stenosis, a small spinal canal is produced by short pedicles and thick laminae (62). It commonly remains asymptomatic until degenerative changes are superimposed on the congenital stenosis later in life. Acquired stenosis can be produced by a host of hyper- trophic degenerative […]
