Diagnosis: Unspecified abnormalities of gait and mobilityClinical question: altered gaitSigns and Symptoms: altered gait MRI thoracic spine:The thoracic vertebral bodies are appropriate in the overall alignment and height. The thoracic spinal cord has normal signal characteristics and overall morphology. There is no compromise of thoracic spinal canal or exiting nerve roots. Lumbar spine: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 left-sided hemilaminectomy at the L4-5 level.At L5-S1 there is no significant compromise to spinal canal or neural foramina.At L4-5 there is no significant compromise to spinal canal or neural foramina. There is loss of disc space height, disc desiccation and a broad-based left lateral disc protrusion at this level. The fat at the lateral recess on the left side is mildly effaced.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.There are some degenerative changes present lumbar spine worse at L4-5 without significant compromise to spinal canal or exiting nerve roots. There is mild displacement of the nerve roots at the left lateral recess at L4-5 due to a small left lateral recess disc protrusion.2.No spinal cord lesions or compromise to the spinal cord is appreciated in the thoracic spine.
