Clinical question: Status post cervical fusion. Signs and symptoms: Same Nonenhanced CT of cervical spine:Routine non-infused axial 3-mm CT images of the entire cervical spine were obtained. Sagittal and coronal 2-D reformatted images were also obtained.Examination demonstrates very advanced degenerative disk disease at C3 -- C4 through C6 and C7 levels.Antral listhesis of C3 in respect to C4 is again identified with no appreciable change since prior MRI exam.There is evidence of posterior fusion with placement of bilateral trans-facet fixating screws at C3 level. There is also wide bilateral laminectomy at this level.Evidence of bilateral trans-facet screws placement at C4. No evidence of laminectomy. Fixating metallic rods bilaterally at C3 there C4 levels are also present.There is no evidence of any fracture of the instruments. The appropriateness of the position of the screws should be decided by referring clinical physician.Expected postoperative changes of air in the surgical site. No evidence of intracanalicular air.
