A small-sample study examining the cervical spine in symptom-free volunteers found focal disc protrusions in 50% of participants, suggesting that a considerable part of the population might have focal herniated discs in their cervical region that do not cause noticeable symptoms. [4] [5] A herniated disc in the lumbar spine may cause radiating ...
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.
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]
Percutaneous disc decompression: A procedure that reduces or eliminates a small portion of the bulging disc through a needle inserted into the disc, minimally invasive. Spinal decompression: A non-invasive procedure that temporarily (a few hours) enlarges the intervertebral foramen (IVF) by aiding in the rehydration of the spinal discs. Spinal ...
In addition to spinal stenosis, other lower back conditions such as spondylosis, tumors, infections and herniated or ruptured discs can cause NC. These conditions contribute to the potential narrowing of the spinal cord, increasing pressure and inducing damage on the spinal nerve roots, thus, causing paing, tingling or weakness in the lower ...
Jensen and colleagues, in an MRI study of the lumbar spine in 98 asymptomatic adults, found that in more than half, there was a symmetrical extension of a disc (or discs) beyond the margins of the interspace (bulging). In 27 percent, there was a focal or asymmetrical extension of the disc beyond the margin of the interspace (protrusion), and in ...
