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 cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel ...
Spinal stenosis is the single most common diagnosis that leads to spinal surgery, of which a laminectomy represents one component. The lamina of the vertebra is removed or trimmed to widen the spinal canal and create more space for the spinal nerves and thecal sac .
Historically, laminectomies have been the primary way to treat lumbar spinal stenosis. [5] A laminectomy is a more invasive method with the aim to decrease the total amount of pain and numbness associated with lumbar spinal stenosis. [2] It is a surgery that eliminates the entire lamina to allow the nerves around this region to function ...
The C2 to C7 laminae are drilled at the lateral borders of the laminae. One side of the bone is completely cut, while the other side acts as a hinge. The laminae are then lifted to increase space in the spinal canal. The flap of the laminae is kept open with a suture that is fixed to the facet capsule. [1] [5]
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 (ESI) is a technique in which corticosteroids and a local anesthetic are injected into the epidural space around the spinal cord in an effort to improve spinal stenosis, spinal disc herniation, or both. It is of benefit with a rare rate of major side effects. [1] [2]
