I have the same thing. It means a bone spur that sticks out into the opening (channel) that the nerve passes through. The bone spur can put pressure on the nerve, causing muscle weakness (loss of function) and/or pain. If aggravated by motion, tis pressure can cause muscle spasm and increased pain. If the bone spur breaks off in there I guess things can get even worse, although nobody has told me there's huge risk of this.
I do have loss of function in a couple of left leg muscles, but this may be from L4 disk herniation, for which I'm working on physical therapy steps (gentle and specific stretching -- particularly gentle "sagged" push-up, i.e., legs to belly-botton stay on floor, hamstring and quad and groin stretching; and specific strengthening of weak muscles.
My physical therapist advises that it may take a year to build back function, but that if no severe pain, injections or surgery are likely not going to get me there any quicker.
The pedicles, laminae and the intervertebral foramina form the vertebral arch.
Transverse foramina are small openings within the transverse processes of the cervical vertebrae. These foramina allow the passage of the vertebral artery and vertebral veins, which supply blood to the spinal cord and brain.
Cervical vertebra - typical The cervical vertebrae contain foramina in the transverse processes, called foramina transversarium.
The vertebral foramina is where the spinal cord passes through the vertebrae (bone).
Vertebral foramen are the spaces between adjacent vertebrae where the spinal nerves exit the spinal canal.
vertebrae Inter means "between", vertebral obviously means vertebrae as mentioned above, and foramina is plural for foramen, which is a hole. Intervertebral foramina are formed in the space between two vertebrae. When two or more vertebral bones are stacked, the intervertebral foramina would be inferior to the pedicles of the superior vertebrae and superior to the pedicles of the inferior vertebrae. It will create a hole that goes between the two vertebrae horizontally. The spinal cord goes through the vertebral foramen vertically, and the nerve roots slip out horizontally through the intervertebral foramina.
No veins pass through the the transverse foraminae. The vertebral arteries, however, pass through these spaces on their way to the brain.
What are the symptoms and treatments for degenerative changes lumbar spine with multilevel foramina encroachment
Spinal nerves exit the vertebral column through small openings called intervertebral foramina located between adjacent vertebrae.
Foraminal encroachment refers to that degeneration in the spinal column which causes the obstruction of the foramina.
intervertebral foramina
Transverse foramina are found in the cervical vertebrae of the spine. They are openings on the sides of these vertebrae that allow passage of the vertebral arteries and veins which supply blood to the brain.
