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).
What else can I help you with?
What is lumbosacral junction?
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.
Moderate to severe degenerative loss of disc height at the lumbosacral junction with mild degenerative type posterior subluxation and associated broad-based annular disc bulge which is subligamentous?
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)...
What does loss of disc signal at L4-L5 and L5-S1 mean?
No
What is transitional lumbosacral vertebra?
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.
What is subluxation of L4 and L5?
whatis anterior subluxation on L5 on S1 mean?
What does moderate arthropathy L-4-L5 and L-5-S1 mean?
what does moderate facet arthropathy l5-s1 mean
What superior articular process of the sacrum articulate?
The superior articular process of the sacrum articulates with the inferior articular process of the last lumbar vertebra (L5) to form the lumbosacral joint.
What is encroachment of the neutral foramen on the left at L3-4 atrributed to disc bulging and what is transitional lumbosacral segment at L5-S1 associated with mild disc bulging?
Encroachment of the neutral foramen on the left at L3-4 due to disc bulging indicates that the intervertebral disc is protruding and compressing the nerve root exit point, potentially leading to symptoms like pain or numbness in the corresponding lower limb. A transitional lumbosacral segment at L5-S1 suggests an anatomical variation where the L5 vertebra may exhibit characteristics of the sacrum, which can predispose this area to abnormal stress and mild disc bulging. This bulging may further contribute to nerve root irritation or compression at this transitional segment.
What does sacralization of L5 vertebrae with right transverso-iliac neo-articulation mean?
left sided sacralisation of L5 vertebra seen
What joint connects the sarcum with the upper verterbrae?
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 endplate changes at the L5-S1 level mean?
what does slight progression of degenerative marrow in the l5 - s1
Which spinal nerves comprise the brachial plexus and the lumbosacral plexus?
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.
