Fractures to the wrist are the most common in children under age 16; snowboarding causes the most fractures per hour of exposure
ROSEMONT, Ill., April 8, 2013 /PRNewswire-USNewswire/ -- While broken bones are not uncommon in children, a new study appearing in the April 2013 Journal of Bone and Joint Surgery (JBJS) looks at which fractures are most common in children, and which activities are most likely to cause fractures.
Approximately one-third of pediatric fractures occur during sport or recreational activity. In this Norwegian study, researchers sought to determine the incidence and causes of pediatric fractures in children under age 16 by evaluating 1,403 fracture cases over a 12 month period. Exposure time to the most common childhood activities was measured through random interviews with parents in the study population.There was an overall annual incidence rate of 180.1 fractures per 10,000 children. The distal radius, or wrist, was most often fractured (436 fractures, or 31.1 percent of all injuries), followed by fingers (436 or 31.1 percent) and toes (247 or 17.6 percent). Snowboarding was associated with the highest activity-specific fracture rate (out of 15 activity categories), estimated to be 1.9 fractures per 10,000 hours of exposure, which is four times higher than the fracture rates for soccer, and five times higher than trampoline use. "In our study we discovered that snowboarding caused four times more fractures per exposure time compared to other common childhood activities," said orthopaedic surgeon and lead study author Per-Henrik Randsborg, MD, Ph.D. "Furthermore, trampoline use did not seem to cause more fractures per hours of exposure than other popular childhood activities. In fact, handball and soccer had a higher risk of fractures than did trampoline use."
