Patient description: 44-year-old female had previously underwent a laminectomy for a disc herniation. Patient presented with new onset of bilateral radicular leg pain without an antecedent history of trauma. Initial radiographic imaging showed laminectomy defect with degeneration at L4-5 and L5-S1. She initially underwent non-operative care, including PT/OT, steroid dose pack, and home stretching exercises. Pain continued and an MRI was ordered which showed significant foraminal stenosis at L5-S1 with facet arthropathy and significant disc degeneration. At the L3-4 and L4-5 levels, she was found to have facet arthropathy with disc height and foraminal collapse and further lateral recess/foraminal stenosis.
