Question: What is the outlook for Erb-Duchenne and Dejerine-Klumpke Palsies ?
Answer: The site and type of brachial plexus injury determines the prognosis. For avulsion and rupture injuries, there is no potential for recovery unless surgical reconnection is made in a timely manner. The potential for recovery varies for neuroma and neuropraxia injuries. Most individuals with neuropraxia injuries recover spontaneously with a 90-100 percent return of function.
