It would mean that through injury or disease, some part of your spinal anatomy had become shortened, or narrowed.
One of them should be correct, normally.
Tethered Spinal Cord is a condition where the spinal cord is attached to the spinal column and that causes the cord to become stretched.
cervical spinal nerves, thoracic spinal nerves, lumbar spinal nerves, sacral spinal nerves
Nerve root effacement refers to nerve root compression. This is an issue where the root of the nerve is compressed into the spine before exiting it, which can cause some painful back symptoms.
You have protrusion of the disc between thoracic six and seventh vertebrae. This protrusion has created indentation on the sac of dura matter on the anterolateral region of the spinal cord. This can compress your spinal cord.
MRI results have effacement ventral cerebrospinal fluid space
Complete effacement of the thecal sac refers to a condition where the space surrounding the spinal cord (thecal sac) is compressed or narrowed to the point where it is no longer visible on imaging studies such as MRI. This can be due to disc herniation, spinal stenosis, or other spinal abnormalities, and may result in symptoms such as pain, numbness, or weakness in the back or extremities. Treatment may involve conservative measures like physical therapy, medications, or in severe cases, surgical intervention.
