Spinal canal stenosis

It is produced by the progressive decrease in lumbar canal diameter due to the degenerative process on the intervertebral disc, articular facets and the yellow ligament (flavum). The main symptoms are neurogenic claudication of gait and pain radiating to the lower limbs that increases with standing.


When conservative treatment through oral medication, physiotherapy and peridural infiltration is exhausted, the surgery of choice is to expand the spinal canal through laminectomy and foraminal release. Depending on each case an instrumentation could be required.
