title: Bilateral symptomatic supernumerary muscle belly syndrome.
abstract: A 32-year-old woman with a longstanding history of bilateral forearm pain had been unable to open her fingers and use her left arm (treated as reflex sympathetic dystrophy) since the age of 14. On physical examination there was fullness and tenderness of the distal volar forearms bilaterally; the quadriga test (when the patient was asked to make a tight fist quickly, with one finger fully extended passively) elicited burning pain. Operation confirmed that she had anomalous reversed forearm muscles bilaterally, and these were successfully resected.
