• Normal segmentation and alignment with grade 1 retrolisthesis at L4/L5 and grade 1 anterolisthesis at L5-S1. Interbody fusion surgery has been performed at L5/S1, with bilateral pedicle screws, interconnecting rods and an interbody cage. Metalwork positioning appears satisfactory, allowing for the artefact.
• The bilateral L5 neuroforamen are elongated and narrowed, with potential for mild neural compression. This is of uncertain clinical significance given the fusion at L5/S1.
• There is mild oedema within the superior articular facet of the left L4/L5 facet joint, most suggestive of a stress response, but without the discrete fracture present. A trace of fluid is present in the left L3/L4 facet joint.
