Reason: Pathology to explain low back pain with radicular symptoms down R leg History: Back Pain R thigh pain 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.Patient is status post pedicle screw placement at L4 and L5 for posterior fusion and laminectomies at L4 and L5.At L5-S1 there is no significant compromise to spinal canal. There is loss of disk space height disk desiccation, diffuse disk bulge there is bilateral facet hypertrophy at this level a mild to moderate degree. The exiting nerve roots within the neural foramina are surrounded by fat at this level.At L4-5 there is no significant compromise to spinal canal or neural foramina. There is loss of disk space height disk desiccation, diffuse disk bulge there is bilateral facet hypertrophy at this level a mild to moderate degree. There is mild intra-subluxation of L4 on L5.At L3-4 there is loss of disk space height comment this desiccation, diffuse disk bulge and moderate bilateral facet and ligamentum flavum hypertrophy with triangulation of the thecal sac and overall mild to moderate degree of spinal stenosis. There is narrowing of the neural foramina bilaterally with some mild encroachment of the exiting nerve roots within the neural foramina .At L2-3 there is no significant compromise to spinal canal or neural foramina. There is disk desiccation and a mild disk bulge at this level.At L1-2 there is no significant compromise to spinal canal or neural foramina.
1.The patient is status post posterior fusion and laminectomies at L4 and L5.2.There is redemonstration of degenerative changes in the lumbar spine with mild to moderate spinal stenosis at L3-4 associated with encroachment on exiting nerve roots within the neural foramina. This is stable compared to the previous exam
