Insights
Childhood fractures are common, increasing with age. Fractures, especially leg fractures, significantly restrict children's activities, with arm fractures being most frequent.
Area of Science:
- Pediatric orthopedics
- Epidemiology of childhood injuries
Background:
- Fractures are a common pediatric injury.
- Understanding fracture incidence and functional impact is crucial for child health.
Purpose of the Study:
- To determine the incidence of fractures in children aged 0-12 years.
- To assess the activity restrictions associated with different fracture types in this age group.
Main Methods:
- Prospective injury recording over four years (1992-1995) in a large cohort.
- Parental questionnaires collected data on activity restriction for a subsample of children with fractures.
Main Results:
- 2477 fractures occurred, with an incidence of 128 per 10,000 children annually.
- Fracture incidence increased linearly with age.
- Leg fractures resulted in the longest activity restrictions (mean 26 days), followed by arm fractures (mean 14 days).
Conclusions:
- Fracture incidence rises throughout childhood.
- The type of fracture significantly influences the duration of activity restriction in children.
Objectives:
The study's objective was to examine incidence of fractures and associated activity restriction among children aged 0-12 years.
Design:
Injuries were prospectively recorded over the four year period from 1992-95 in a cohort of children aged 0-12 years, representing 193,540 children years. Information about length and extent of activity restriction was collected from parents by a mailed questionnaire for a subsample of 192 children with a fracture.
Results:
A total of 2477 fractures occurred in the study population (128 per 10,000 children annually). The incidence increased linearly with age, by 14 cases per 10,000 children year for each year of age. Boys and girls showed similar patterns of fracture occurrence. There was a significant difference in length of activity restrictions for different types of fractures. The mean and 95% confidence interval (CI) of activity restricted days for leg fractures were 26 (95% CI 7 to 45) days, for arm fractures, 14 (95% CI 8 to 20) days, and for other fractures, 5 (95% CI 1 to 8) days. Arm fractures represented 66% of the cases and 62% of the activity restricted days; leg fractures 19% of cases and 33% of all activity restricted days; and other fractures 16% of the cases but only 5% of the activity restricted days in this population.
Conclusion:
The incidence of fractures increases in childhood. Different types of fractures among children cause different amounts of activity restriction.
