52-year-old male status post cervical spine fusion, with neck pain The alignment of the cervical spine is preserved. Again noted are post surgery change statu post C1/2 fusion and stabilization change. Stabilization screws and plates runs between the occipital bone and C2 laminar are stable in position when compared to previous MRI study. The ends of both occipital screws seem crossing through the inner table of the calvarium. The cross-axial screws at C2 seems crossing through the inner table of the right lamina. No radio lucency is observed surrounding all the hardwares.Coronal images again demonstrate tilting of the dens. The joint space between the left occipital condyle and C1 arch and between the C1 and C2 have been fused by dense material. The degree of the tilting of the dens has been stable when compared to previous study dated 9/9/2011. The hardware obscures full emaculation of the cervical spine at this level, however, no apparent bony canal or neural foramina compromise is observed.Stable mild degenerative change at other level of cervical spine with no evidence of bony canal or neural foramina compromise.
1. Post C1/2 fusion and stabilization change. Stabilization screws and plates runs between the occipital bone and C2 laminar are stable in position when compared to previous MRI study. The ends of both occipital screws seem crossing through the inner table of the calvarium. The cross-axial screws at C2 seems crossing through the inner table of the right lamina. No radio lucency is observed surrounding all the hardwares.2. Stable C1/2 position. No evidence of bony canal or neural foramina compromise at any level.
