The craniocervical junction is intact.
Normal spinal alignment preserved. Straightening of the cervical lordosis.
No vertebral body fractures or facet joint dislocations. Previous ACDF involving C6, C7, and T1.
There is loosening of the T1 screws and residual instability (without static subluxation) at C7-T1.
Anterior plate well applied.
No regions of high-grade cervical canal or neural foramen stenosis.
This case shows loosening of the T1 ACDF screws characterised by a rim of lucency around the screw, which exceeds 2 mm.
