All good.
The prevalence of cervical facet arthrosis increases with age, and occurs more commonly in the upper cervical spine.

Results: In the entire population of
465 specimens, the upper cervical specimens appeared to be affected by facet arthrosis more frequently than the lower levels;
12.37% of the specimens had bony evidence of arthrosis at the C2-C3 level; 13.33% of the specimens had arthrosis occur at the C3-C4 level; 14.62% at the C4-C5 level; 7.85% at the C5-C6 level, and 4.84% at the C6-C7 level. The large majority of all cervical facet arthrosis was found to be Grade 1 at all levels. In the older population, the prevalence of facet arthrosis is as high as 29.87% for the C4-C5 level. C4-C5 level appears to be affected the most frequently, followed by the C3-C4 level, then C2-C3, C5-C6, and C6-C7.
It seems that upper cervical levels are more likely to degenerate and to have more advanced degrees of degeneration than the lower cervical levels. As expected, age correlates with worsening degeneration. The proposed computed tomographic grading system for cervical facet arthrosis seemed to be...

Results:
Facet arthrosis is common with older patients and at C2-C3, C3-C4, and C4-C5. Facet arthrosis was more common on the left side and in males. Greater than grade III facet joint arthrosis was common in patients older than 60 and at C2-C3, C3-C4, and C4-C5. The reliability statistics by intraclass correlation for the grading system was 0.878 for the intraobserver reliability and 0.869 for the interobserver reliability.
The prevalence of cervical facet oedema is 9%. Cervical facet oedema is associated with ipsilateral radiculopathy. Neuroforaminal narrowing, however, is not associated with facet oedema.

One hundred and seventy-three MRI studies with cervical facet oedema were evaluated by each of the two radiologists. In these patients, the grade of bone marrow oedema (BMO) and corresponding neuroforaminal narrowing at the cervical facets was assessed. Correlation with symptoms was performed based on pre-MRI questionnaire.
Results: The prevalence of cervical facet oedema was 9%;
the most commonly affected levels were C3-4, C4-5, and C2-3. A total of 202 cervical facets were evaluated:
