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.
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
Foraminal encroachment refers to that degeneration in the spinal column which causes the obstruction of the foramina.
The Transverse foramina and the vertebral foramen All cervical vertebrae have 3 foramina (holes) -- 1 vertebral foramen and 2 transverse foramina. All other vertebrae have only 1 foramen, the vertebral.
Cervical vertebrae possess transverse foramina to allow for the vertebral arteries to pass through on their way to the foramen magnum to end in thecircle of Willis.
The spinal nerves exit from the vertebral column through openings between adjacent vertebrae. These openings, called intervertebral foramina, are located just in front of the facet joints. They exit from what are called intervertebral foramina (foramen means opening).
