Entrapment: Complex Regional Nerve Pain After Trauma

Animation: Sciatic nerve hyperintensity associated with adhesion to a site of pelvic fracture.
(A) Sciatic nerve hyperintensity associated with adhesion to a site of pelvic fracture in a patient with new onset reflex sympathetic dystrophy (RSD). The RSD symptoms resolved after nerve release surgery.
(B) Deformation in the shape of the sciatic nerve at a site of prior trauma and failed surgical exploration.
(B1) This reconstruction in the sagittal plane shows a flattened sciatic nerve with an irregular course instead of the expected straight smooth course.
(B2) In the coronal view the sciatic nerve is broad and flat. The two images together show the severe mechanical distortion of the nerve at this site of adhesion. After four years of failed intensive pain management, the symptoms were relieved by nerve release surgery.
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.
