Animation: Marked hyperintensity of the recurrent branch.
This animation depicts severe impingement syndrome affecting the recurrent branch of the median nerve in the wrist.
A 62-year-old woman suffered severe denervation of thenar muscles with no other symptoms of carpal tunnel syndrome after casting for a wrist fracture.
The image demonstrates marked hyperintensity of the recurrent branch as it separates from the median nerve.



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.
