Animation: Adiculopathy exacerbated by lumbar spine instrumented fusion.
(A) 59-year-old woman with persistent severe left S1 radiculopathy exacerbated by lumbar spine instrumented fusion and not relieved by subsequent removal of the instrumentation. The image demonstrates perforation of the left S1 root by the course of the pedicle screw (ps). No further surgical treatment was recommended.
(B) Persistent sciatica after a fall with no improvement after discectomy. The image demonstrates inflammation around the nerve (S1) consistent with a sacral fracture (fx) abutting the foramen.
(C) The MR Neurography imaging protocol results in an MR myelogram as well as Neurographic images of the exiting nerve roots.
Dr. Aaron Filler is the world’s leading expert in treatment of nerve pain. He has revolutionized nerve-pain treatment by inventing several new technologies. One such technology, MR Neurography, enables doctors to use an MRI scanner to examine nerves — previously a difficult-to-impossible tissue to see through MR imaging. Dr. Filler's research in axonal transport is leading to a whole new generation of advanced pain medications. He has developed many new “minimal access” surgery methods that allow him to treat complex nerve problems with small outpatient surgeries. He has also pioneered the use of the Open MRI scanner to do surgeries and other therapies with the ultra-high precision and safety of the magnetic resonance imaging. 
Do You Really Need Back Surgery? by Dr. Aaron G. Filler, MD PhD, is a best-selling paperback every sufferer of spine and nerve pain should read. Written in everyday language, the book is a must-read.
