The mean age was 28.6 months (612.6). The left arm was affected 60% of the time.Most of the included patients were over the 75th percentile for weight and more than one quarter wereover the 95th percentile in each gender.Conclusion: 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.
