title: Epidemiology of nursemaid's elbow.
abstract: BACKGROUND
  To provide an epidemiological description of radial head subluxation, also known as nursemaid's elbow, from a database of emergency department visits.
  
  
  METHODS
  We conducted a retrospective medical record review of patients 6 years of age and younger, who presented to the ED between January 1, 2005, and December 31, 2012, and were diagnosed with nursemaid's elbow. Inclusion criteria consisted of chart information, including date, unique account number, medical record number, weight, age, sex, and arm affected. Exclusion criteria included any charts with missing or incomplete data.
  
  
  RESULTS
  There were 1,228 charts that met inclusion criteria. The majority of patients were female (60%). The mean age was 28.6 months (±12.6). The left arm was affected 60% of the time. Most of the included patients were over the 75(th) percentile for weight and more than one quarter were over the 95(th) percentile in each gender.
  
  
  CONCLUSIONS
  The average age of children presenting with nursemaid's elbow was 28.6 months. Females were affected more than males, and the left arm was predominately affected. Most patients were above the 75(th) percentile for weight and more than one quarter were over the 95(th) percentile for weight.
