Nursemaid's elbow (subluxation of the radial head) is a common pediatric upper 
extremity injury encountered in the emergency and urgent care settings. 
Subluxation of the radial head accounts for more than 20% of upper extremity 
injuries in the pediatric population. A clinical case of a three-year old girl 
who presented to the emergency department with a nursemaids elbow requiring 
reduction is presented in this article. The purpose of this article is to 
discuss the identification and treatment of this injury and delineate the two 
methods of supination and pronation for reduction of the annular ligament.
