Neck pain or failed cervical fusion?

Patient: I had ACDF back in September of 2014. Since then I’ve experienced worsening pain. I recently had a CT Scan and flexion/extension x-ray done to see if the fusion was fusing correctly or if there are any new issues. I was hoping someone could take a look at the films to see if there was anything noticable.

Symptoms: Neck pain, sharp pains radiating to side of face

Doctor:
