History of previous cervical fusion with neck and left arm pain. Again seen is an anterior plate with screws directed into the C5 and C6 vertebral bodies. A spacer device is again noted between the C5 and C6 vertebra. The C4-C5 and C5-C6 disc spaces are indistinct suggesting some osseous fusion, overall increased from prior. Also again noted is lucency surrounding the C5 screws and anterior tilting of the superior aspect of the plate again concerning for loosening appearing similar to prior. Mild loss of height of the C4, C5, and C6 vertebral bodies better characterized on prior MRI appears similar to prior.There is loss of the normal cervical lordosis. There is no evidence of instability on flexion and extension views. The upper cervical neuroforamina appear grossly patent. The lower cervical neural foramina are obscured by overlying anatomy.
Postoperative changes of ACDF as described above without evidence of instability.
