Status post L3-L5 fusion, planning to extend the sacrum Five lumbar type vertebral bodies are presumed to be present. Grade 1 anterolisthesis of L5 on S1 is better seen on prior upright radiograph. Vertebral body heights and alignment are otherwise maintained. Bone marrow signal is benign. The conus medullaris is normal in position. Postoperative changes of spinal fusion from L3 to L5 are again seen with hardware better assessed on recent CT. Left L5 pedicle fracture also better seen on same-day CT.Susceptibility artifact related to the hardware slightly limits assessment. Degenerative changes as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. Interbody fusion. No spinal canal or neural foraminal stenosis.L4-L5: Interbody fusion. Mild disc bulge eccentric to the right with mild right neural foraminal narrowing. No spinal canal or left neural foraminal stenosis. Small extradural fluid collection, likely postoperative, in the left laminectomy bed.L5-S1: Disc bulge and moderate bilateral facet arthropathy. There is mild to moderate bilateral neural foraminal stenosis with susceptibility artifact limiting evaluation.
1. Postoperative changes of L3-L5 fusion. No significant spinal canal stenosis at any level. There is mild to moderate bilateral L5-S1 and mild right L4-L5 neural foraminal stenosis.2. Left L5 pedicle fracture better seen on same-day CT. There is moderate bilateral L5-S1 facet arthropathy. Grade 1 anterolisthesis at this level is appreciated on upright radiographs.3. Please see same day CT report for additional findings.
