MRI of the cervical spine. C. 2-C3: Small central disc protrusion and bilateral facet arthrosis causing mild central canal stenosis without neuroforaminal narrowing (yellow arrow).C3-C4: Bilateral facet arthrosis and uncovertebral joint osteophytes causing mild to moderate bilateral neuroforaminal narrowing without central canal stenosis. Bilateral foraminal nerve root encroachment (green arrows).C4-C5: Central disc protrusion causing moderate central canal stenosis. There were bilateral uncovertebral joint osteophytes and facet arthritis causing severe right and moderate left neuroforaminal narrowing with right foraminal C5 nerve root impingement and left foraminal C5 nerve root encroachment (blue arrows).C5-C6: Posterior disc osteophyte complex causing moderate to severe central canal stenosis. There are bilateral uncovertebral joint osteophytes and facet arthrosis resulting in severe bilateral neuroforaminal narrowing with bilateral foraminal nerve root impingement (red arrows).C6-C7: No central canal stenosis or neuroforaminal narrowing (orange arrow).
