Which intervertebral disc is the largest?
The largest intervertebral disc is typically found between the fourth and fifth lumbar vertebrae in the lower back. This disc is known as the L4-L5 disc and tends to be larger due to the increased weight-bearing and range of motion demands placed on the lower back.
The left transpediclar screw at the L5 level demonstrates subtle superior encroachment into the anterior inferior aspect of the intervertebral disc space at L4-L5?
The screw on the left in the fifth vertera in the lower back is sticking up a tiny bit into the space above it.
What is marginal osteophytes at L4 and L5 with reduced disc space?
MR imagemorphology is in favour of early marginal osteophytes at few levels. mildbroad disc bulge at l4-l5 causing minimal thecal sac indentation
What is intervertebral Disc Displacement Lumbar?
An intervertebral disk in which the nucleus pulposus has protruded through surrounding fibrocartilage. This occurs most frequently in the lower lumbar region. Alternative terms: Intervertebral Disk Displacement; Disk Displacement, Intervertebral; Disk Displacements, Intervertebral; Displacement, Intervertebral Disk; Displacements, Intervertebral Disk; Intervertebral Disk Displacements; Intervertebral Disc Displacement; Disc Displacement, Intervertebral; Disc Displacements, Intervertebral; Displacement, Intervertebral Disc; Displacements, Intervertebral Disc; Intervertebral Disc Displacements; Disk, Herniated; Disks, Herniated; Herniated Disk; Herniated Disks; Slipped Disk; Disk, Slipped; Disks, Slipped; Slipped Disks; Disk Prolapse; Disk Prolapses; Prolapse, Disk; Prolapses, Disk; Prolapsed Disk; Disk, Prolapsed; Disks, Prolapsed; Prolapsed Disks; Herniated Disc; Disc, Herniated; Discs, Herniated; Herniated Discs; Lumbar is referring to the lower back L1-L5
Are there vertebral discs in the sacrum?
No. There are no intervertebral discs in the Sacrum. The Sacrum is a fusion between 5 vertebrae and this the same with the Coccyx (fusion of 3). The final intervertebral disc is between L5 and the superior surface of the Sacrum.
L4 - L5 considerable disc space narrowing and desiccation with broad-based posterior and posterolateral extension of inteervertebral disc with midline annular tear?
broadbased narrowing at the l5/s1
Can the L5 disc slip forward by a fall?
can your L5 disc slip foward by a fall on your back
Is there any disc between S1 and S2 vertebrae?
No. The L5-S1 Intervertebral disc is the last disc in the spine because the 5 segments of the sacrum and the 4 segments of the coccyx are fused (though they are seperated from each other by a ligament).
Degeneration of L5-S1 disc with vacuum phenomenon?
Degeneration of the L5-S1 disc refers to the breakdown or wear-and-tear of the disc located between the fifth lumbar vertebra and the first sacral vertebra in the spine. The vacuum phenomenon is a radiographic finding where gas accumulates within the intervertebral disc space, typically seen in degenerated discs. This phenomenon is a result of the degenerative changes in the disc causing a decrease in pressure within the disc space, allowing gas to enter and form a vacuum. This condition can be associated with back pain, radiculopathy, and other symptoms related to spinal degeneration.
What is loss of intevertebral disc signal?
Loss of disc signal is something commonly seen on an MRI report. It means that there has been some degeneration of the disc.
What does loss of disc signal at L4-L5 and L5-S1 mean?
No
What does this mean from an MRI L5 S1 disc space is mildly narrowed and the disc is desiccated reactive signal changes in the adjacent vertebral bone marrow?
If you had an MRI and have a mildly narrowed disc space between L5 S1, it sounds like you have a slightly herniated disc. Whenever your doctor gives you a diagnosis, it is best to ask as many questions as possible such as treatment options, pain management, etc.
