Age is usually conception to be a distress part in defining lumbar spinal stenosis (LSS) degenerative or developmental subtypes. This text is a apply-up to a outdated article (“Redefining Lumbar Spinal Stenosis as a Developmental Syndrome: An MRI-Based entirely mostly Multivariate Diagnosis of Findings in 709 Patients At some stage within the 16- to 82-Year Age Spectrum”) that describes the radiological variations between developmental and degenerative forms of LSS. MRI-based entirely diagnosis of “degeneration” variables and spinal canal morphometric traits of LSS segments had been conception to correlate with age at presentation.


The authors performed a re-diagnosis of data from their previously reported ability MRI-based entirely watch, stratifying records from the 709 cases into 3 age categories of equal dimension (somewhat than the customary < 60 vs ≥ 60 years). Relative spinal canal dimensions, besides to radiological degenerative variables from L1 to S1, had been analyzed across age groups in a multivariate mode. The total degenerative scale procure (TDSS) for every lumbar section from L1 to S1 became calculated for every patient. The relationships between age and qualitative stenosis grades, TDSS, disc degeneration, and aspect degeneration had been analyzed utilizing Pearson's product-moment correlation and a pair of regression.


Multivariate diagnosis of TDSS and spinal canal dimensions revealed extremely predominant variations across the 3 age groups at L2-3 and L3-4 and a weaker, nonetheless composed predominant, affiliation with adjustments at L5-S1. Age helped to shriek very best 9.6% and 12.2% of the variance in TDSS at L1-2 and L2-3, respectively, with a reasonable obvious correlation, and 7.8%, 1.2%, and 1.9% of the variance in TDSS at L3-4, L4-5, and L5-S1, respectively, with pale obvious correlation. Age defined 24%, 26%, and 18.4% of the variance in lumbar intervertebral disc (LID) degeneration at L1-2, L2-3, and L3-4, respectively, whereas it defined very best 6.2% and 7.2% of the variance of LID degeneration at L4-5 and L5-S1, respectively. Age defined very best 2.5%, 4.0%, 1.2%, 0.8%, and zero.8% of the variance in aspect degeneration at L1-2, L2-3, L3-4, L4-5, and L5-S1, respectively.


Age at presentation correlated weakly with degeneration variables and spinal canal morphometries in LSS segments. Age correlated with upper lumbar section (L1-4) degeneration bigger than with lower section (L4-S1) degeneration. The proper chronological age of the sufferers did not vastly correlate with the extent of degenerative pathology of the lumbar stenosis segments. These watch outcomes lend enhance for a developmental contribution to LSS.

Key phrases:

LID = lumbar intervertebral disc; LSS = lumbar spinal stenosis; TDSS = total degenerative scale procure; age; degenerative lumbar stenosis; developmental lumbar spinal stenosis.

What is spinal stenosis?

The spinal stenosis is a narrowing of the spinal canal in the lower part of the spine. This narrowing puts pressure on the spinal cord and/or nerves.

What is the non-surgical treatment of spinal stenosis?

Most cases of spinal stenosis are successfully treated with non-surgical techniques, such as pain relievers and anti-inflammatories. Severe pain can also be treated with corticosteroids that are injected into the lower back (that is, epidural steroid injections). Physical therapy exercises are also prescribed.

What is the surgical treatment of spinal stenosis?

The most common surgery for spinal stenosis is known as a decompressive laminectomy, and it involves removing the lamina (roof) of the vertebra, which increases the space for nerves in the spinal canal. If only part of the lamina needs to be removed, it is known as a laminectomy. If there are herniated discs or bulging discs, they may also be removed (called a discectomy) to increase the space. Sometimes it is also necessary to enlarge the foramen (the area where the nerve roots exit the spinal canal).
