Vertebral height and overall alignment are unremarkable, with minor anterolisthesis of C4 and C5 (2 mm). Fracture of the left C5 the facet is noted, better demonstrated on CT. Despite aforementioned anterolisthesis, the cord is not compressed and appears unremarkable at all levels, without evidence of oedema or haemorrhage. No neural exit foraminal stenosis.
Extensive oedema is seen in the paraspinal musculature on the left side particularly the site of fracture. No significant oedema, however, is demonstrated within the interspinous ligament which appears intact. The ligamentum flava appear unremarkable. Posterior and anterior longitudinal ligaments do not appear disrupted, although small high T2 intensity clefts are seen within the anterior and posterior left-sided annular fibres of the C4/C5 disc raising the possibility of partial tears. No significant oedema is demonstrated on the right side. T
Conclusion: Fracture of left C5 articular pillar, with the C4/C5 left-sided anterolisthesis. No convincing disruption of the main ligamentous structures and no evidence of cord compression or trauma.
