Reason: evaluate for LESI, s/p lumbar surgery with continued LBP, right knee pain and left LE numbness History: evaluate for LESI, s/p lumbar surgery with continued LBP, right knee pain and left LE numbness Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact. The patient is status post laminectomy and posterior fusion with instrumentation at the L3-4 level. There is atrophy of the paraspinous musculature in the lower lumbar spine.At L5-S1 there is no significant compromise to spinal canal or neural foramina. There is mild facet hypertrophy at this level right slightly more than left.At L4-5 there is no significant compromise to spinal canal or neural foramina. There is a disk bulge present at this level associated with ligamentum flavum hypertrophy. The fat at the lateral recess these is not effaced. There is fluid present within the facet joints left more than right.At L3-4 there is no significant compromise to spinal canal or neural foramina.At L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
1.Status post lumbar surgery at L3-4. 2.There are degenerative changes present in the lower lumbar spine without significant compromise to spinal canal or neural foramina.
