* Two methods of reduction can be used: supination and flexion or hyper-pronation.
* New studies are looking like the hyper-pronation may be more effective than the old standard of supination and flexion.. (Bek D et al. Pronation versus supination maneuvers for the reduction of 'pulled elbow': a randomized clinical trial European Journal of Emergency Medicine. 2009, 16(3), 135-8)
Children typically present with a history of having their arm pulled upward and (imagine your child running into the street while you are still standing on the sidewalk) and subsequently refusing to use the arm.
