Dorsal Root Entry Zone (DREZ) Lesion

  • Amgad S. Hanna


This chapter describes dorsal root entry zone (DREZ ) lesion in relation to brachial plexus avulsion . Deafferentation pain is difficult to treat and can sometimes be intractable to medical management. DREZ lesion has an 85 % success rate at 2 years in treating neuropathic pain following brachial plexus avulsion.
