The levels were again confirmed under C-arm and the picture was saved.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The microscope was brought in. The laminotomy of L4 was performed under a microscope using an electric matchstick burr. The ligamentum flavum was raised. The flavum was excised and foraminotomy was performed. The dural sac and the nerve root were retracted medially.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Bipolar cautery was used to achieve hemostasis.
