56 years Male (DOB:9/21/1960)Reason: L5-S1 anterolisthesis History: leg painTech Comments: pt complains of lower back pain with radiating pain on rt buttocksPROVIDER/ATTENDING NAME: MICHAEL J LEE MICHAEL J LEE 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.At L5-S1 there is spondylolysis associated with spondylolisthesis. There is elongation the AP dimension of the spinal canal at this level and approximately 10 mm anterior subluxation of L5 on S1. There is narrowing of the neural foramina bilaterally at this level with encroachment of the nerve roots within the neural foramina. There is loss of disc space height this desiccation and uncovering of the disc. There are bilateral pars interarticularis defects at this level.At L4-5 there is no significant compromise to spinal canal or neural foramina. There is loss of disc space height this desiccation and a disc bulge associated with endplate reactive changeAt 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.Spondylolysis with spondylolisthesis at L5-S1 is associated with encroachment of the exiting nerve roots neural foramina bilaterally.2.Mild degenerative changes at L4-5.
