Leg pain/lumbar radiculopathy. There are postoperative findings related to L4-5 posterior spinal fusion and intervertebral disc spacer insertion. Susceptibility artifact somewhat limits evaluation of these levels. There is approximately 10 mm of anterolisthesis of L4 on L5, which is unchanged. There is moderate right and mild left neural foraminal narrowing, as well as mild right spinal canal stenosis at this level. There is also a disc bulge and hypertrophy of the ligamentum flavum at L3-4, which results in mild bilateral neural foraminal narrowing, as well as slight impingement on the lateral recesses bilaterally. The vertebral body heights are preserved.
1. Postoperative findings related to L4-5 fusion with persistent grade 1 anterolisthesis of L4 on L5 and moderate right and mild left neural foraminal narrowing, as well as mild right spinal canal stenosis at this level. 2. A disc bulge and hypertrophy of the ligamentum flavum at L3-4 results in mild bilateral neural foraminal narrowing, as well as slight impingement on the lateral recesses bilaterally.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
