Your spinal cord is made up of 5 different areas, based on how many vertebrae (pieces of spine) make it up.
You have:
7 CERVICAL
12 THORACIC
5 LUMBAR
5 SACRAL
5 COCCYGEAL
Therefore the lumbosacral junction (where lumbar meets sacral) is assumed to be at L5 (the 5th and last lumbar vertebrae) and S1 (the 1st sacral vertebrae).
The lumbosacral junction is located in the lower center of the back and between the hips. It consists of the L5 vertebral and the first sacral vertebral body.
Fairly rare MRI term associated with spondylolisthesis at the L5/S1 level... The disk is dragged forward by the spinal slippage and on MRI appears to be herniated (which it isn't)...
Transitional lumbosacral vertebra is a condition where the last lumbar vertebra (L5) is partially fused with the first sacral vertebra (S1). This can lead to variations in the anatomy and function of the lower back and pelvis, potentially causing pain or discomfort. It is a common anatomical variant that may be seen in some individuals.
No
whatis anterior subluxation on L5 on S1 mean?
what does moderate facet arthropathy l5-s1 mean
The superior articular process of the sacrum articulates with the inferior articular process of the last lumbar vertebra (L5) to form the lumbosacral joint.
The sacrum is connected to the upper vertebrae by the sacroiliac joint. This joint provides stability and allows for a small amount of movement in the pelvis. It is a strong joint that is supported by ligaments and muscles.

what does slight progression of degenerative marrow in the l5 - s1
The brachial plexus is formed by the spinal nerves C5-T1, while the lumbosacral plexus is formed by the spinal nerves L1-S4. These plexuses are networks of nerves that supply motor and sensory innervation to the upper and lower limbs, respectively.
It means you have a slight herniation/slight bulging of the disc at the L5-S1 level of your spine.
