Occurrence and treatment of pain after brachial plexus injury.

The occurrence of pain was investigated in 118 patients with posttraumatic brachial plexus injuries (BPI). Ninety-five patients were operated upon by the same surgeon. Three to 14 years after BPI and reconstructive surgery, 91% of the patients experienced permanent pain that was severe in 40% and mild in 51% of cases. When early reconstructive surgery was successful, a significant decrease in pain occurred more frequently. For 57% of patients with pain, a plurimodal medical treatment with tricyclic antidepressants, antiepileptic drugs, and behavioral therapy efficiently reduced pain. For the patients with unbearable paroxystic pain, when medical treatment failed, the destruction of deafferented dorsal horns at the level of avulsion (Nashold procedure) could produce pain relief. In all cases psychosocial management produced early rehabilitation.
