Assess for right L5 radiculopathy. Pain in the right lower extremity Five lumbar type vertebral bodies are presumed to be present. Again seen are postsurgical changes of posterior spinal fusion with hardware extending from the L2 to the S1 levels bilaterally. Paraspinous rods and pedicle screws as well as interconnecting rod at the L3 level are better assessed on prior CT and plain films. Right sacroiliac fusion hardware is also partially visualized.Vertebral body heights are within normal limits. Anterolisthesis of L4 on L5 is again seen as well as minimal anterolisthesis of L3 on L4. Bone marrow signal is benign. The conus medullaris is normal in position.Susceptibility artifact limits evaluation however no high-grade spinal canal or neural foraminal stenosis is appreciated at any level. Nerve roots of the cauda equina appear grossly unremarkable without imaging findings to suggest arachnoiditis.Atrophy of the right psoas muscles again noted.
Postoperative changes of L2-S1 posterior spinal fusion as well as right sacroiliac fusion. Associated susceptibility artifact limits evaluation, however, no high-grade spinal canal or neural foraminal stenosis is appreciated at any level in the lumbar spine. Specifically, no appreciable neural foraminal narrowing at the right L5-S1 level is appreciated. Hardware integrity and position can be better assessed with CT or radiographs.
