2 days ago, I helped the wife of a former NC plastic surgeon who suffered with severe back and leg pain.  She had a previous laminectomy at L45 that gave her only limited and temporary relief, but now her pain and trouble walking and standing grew consistently worse.
Her X-Rays showed a Grade 1 anterolisthesis at L45, with severe lateral recess and foraminal stenosis at L45 with severe facet hypertrophy.
On Tuesday, I performed an L45 revision decompression and fusion with instrumentation.  On mechanical testing of her L45 level, there was significant instability.  Therefore, a TLIF interbody spacer was used to help add additional stability with interbody support to enhance fusion healing, and to jack open disc space slightly for the neural foramen.
She is now doing well, recovering in hospital, and would like to go to a rehab most likely, but is considering also going home with home services.
