Lower back pain post fail...

A 48-year-old female with failed back surgery syndrome (FBSS), presented to the pain clinic with a 29-year history of low back pain, and a 7-year history of sensory and motor dysfunction of her left lower extremity, ever since a left hemilaminectomy. At the time of presentation, she was wheelchair-bound with intense pain, 4/5 strength in her left lower extremity proximally, and 3/5 strength distally. During percutaneous transforaminal endoscopic decompression, her transiting left L5 nerve root was found to be encased in thick scar tissue.
