Conditions affecting the L5-S1 spinal motion segment are usually treated with nonsurgical methods. If the lower back and/or leg symptoms worsen or do not improve despite these treatments, or in case of certain medical emergencies, such as tumors or cauda equina syndrome, surgery may be recommended. Treatment of L5-S1 usually begins with:

The L5-S1 spinal motion segment, also called the lumbosacral joint, is the transition region between the lumbar spine and sacral spine in the lower back. In this region, the curvature of the spine changes from lumbar lordosis (forward curve) to sacral kyphosis (backward curve). L5-S1 helps transfer loads from the spine into the pelvis and legs.

Dec 3, 2020 · The sixth lumbar vertebra is typically located just below the L5 vertebra, making it the lowest vertebra and positioning it next to your tailbone. The extra bone is essentially just a harmless anomaly; sometimes it's because one vertebra failed to fuse with another, but in other cases it's unclear why the bone appeared.

A significant difference in the anterior lumbosacral transitional angle was observed between patients with type-IIIb LSTV and S6 LSTV. The angle in type-IIIb LSTV was lordotic, and its transitional anatomy resembled normal L5-S1, whereas the angle in S6 LSTV ranged from hypolordotic to kyphotic, and its transitional anatomy resembled normal S1-S2.

Feb 14, 2023 · Low back pain affects most adults in their lifetime. The good news is, there are a few L5-S1 exercises you can do to relieve compression and discomfort.

On sagittal CT images, the lumbosacral transitional anatomy of Castellvi LSTVs resembled that of normal L5-S1, and the lumbosacral transitional anatomy of S6 LSTV resembled that of normal S1-S2.

Jan 21, 2018 · Five (or in some cases, six) vertebrae make up the lumbar spine, which provides support for much of the upper body and is rather flexible. Lumbar vertebrae are larger than the thoracic or cervical...

Jul 14, 2021 · On sagittal CT images, the lumbosacral transitional anatomy of Castellvi LSTVs resembled that of normal L5-S1, and the lumbosacral transitional anatomy of S6 LSTV resembled that of normal S1-S2. When comparing the S1 upper segments on axial CT images, most Castellvi LSTVs exhibited S2-like appearances and most S6 LSTVs exhibited L5-like ...

Tubular decompression at the L5-S1 level has its own challenges because of the different anatomy of the L5 lamina compared to that of the L4 lamina. The wide interlaminar angle of L5 as compared to L4 dictates more oblique tube docking (tube angle) and more extensive table tilting to reach the contralateral lateral recess, thus making it ...

The presence of 6 lumbar vertebrae has been reported many years ago [8], with 3% having 6 lumbar, 10% 4 lumbar, 7% 13 thoracic and 3% 11 thoracic vertebrae [7]. There is a great deal of variation in the lumbar plexus. Persons with 6 lumbar vertebrae and a lesion between L5 and L6 can have radicular symptoms at L5, S1, or a combination [4].
