Closed Reduction of a Rostroparasphenopalatal Luxation in a Red-crowned Parakeet (Cyanoramphus novaezelandiae).

A 1-year-old red-crowned parakeet (Cyanoramphus novaezelandiae) was presented with an acute onset of hyperprotraction of the upper beak and an inability to return the beak to its normal position. With the abnormal beak position, the bird was unable to eat. Standard radiographic images of the head supported a diagnosis of a rostroparasphenopalatal luxation. The luxation was reduced with a 23-gauge hypodermic needle inserted dorsal to the palatine bone and directed ventrally. After the procedure, the bird regained its normal beak function within 2 hours.
