80-year-old female patient with weakness. Evaluate for cervical stenosis. Mild to moderate multilevel degenerative changes affect the cervical spine, particularly at C2-C3 and C7-T1. There is is moderate to severe multilevel facet joint osteoarthritis and mild to moderate neuroforaminal narrowing, please refer to recent MRI exam for further details. There is exaggerated cervical lordosis. The anterior atlantodental interval increases to 4-5 mm on flexion view, indicating atlantoaxial instability. There is 2 to 3 mm of retrolisthesis of C2 on C3 that corrects on flexion. There is approximately 1 mm of retrolisthesis of C3 on C4 that corrects on flexion. There is 2 to 3 mm of anterolisthesis of C4 on C5 that is elicited on flexion. There is 3 mm of anterolisthesis of C5 on C6 and 3 mm of anterolisthesis of C6 on C7, both of which are stable between neutral, flexion, and extension views.
Multilevel degenerative disc disease, facet joint osteoarthritis, and multilevel spondylolistheses as described above, including widening of the anterior atlantoaxial interval indicating instability.
