Postoperative radiologic stenosis was very common in patients operated on for lumbar spinal stenosis, but this did not correlate with clinical outcome. The clinician must be cautious when reconciling clinical symptoms and signs with postoperative computed tomography findings in patients operated on for lumbar spinal stenosis. [79]
Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.
Epidural steroid injection for sciatica and spinal stenosis is of unclear effect. [1] The evidence to support use in the cervical spine is not very good. [4] When medical imaging is not used to determine the proper spot for injection, ESI benefits appear to be of short-term benefit when used in sciatica. [5]
Complications of this surgical procedure can include nerve damage to either the nerve roots or the spinal cord, which would result in limb weakness or paralysis respectively. Other complications can include infection, spinal fluid leak, or unsuccessful relief of compression. [6]
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can ...
An epidural often does not cause as significant a neuromuscular block as a spinal, unless specific local anaesthetics are also used which block motor fibres as readily as sensory nerve fibres. An epidural may be given at a cervical, thoracic, or lumbar site, while a spinal must be injected below L2 to avoid piercing the spinal cord.
