While overall fractures in children have declined by 60% during the pandemic, a new study reveals that there’s been an uptick of fractures specifically related to injuries from biking and jumping on trampolines. The Children’s Hospital of Philadelphia found that since COVID-19 forced the closure of playgrounds and parks and schools put an end to organized sports, there’s been a shift in lifestyle that’s resulted in more fractures from alternative forms of home-based recreational activities.

Forbes reported that the researchers found an increase of more than 25% in fractures occurring at home, along with a 12% increase in fractures caused by high-energy falls, like those caused by trampoline and bicycle injuries.

The study, titled "Where Have All the Fractures Gone? The Epidemiology of Pediatric Fractures during the COVID-19 Pandemic," was published in the Journal of Pediatric Orthopaedics in May.

“It is important to remind parents about the importance of basic safety precautions with bicycles and trampolines, as many children are substituting these activities in place of organized sports and school activities,” said Dr. Apurva Shah, senior author of the study and an orthopedic surgeon at CHOP.

“Kids are endlessly inventive in figuring out ways to break bones on trampolines,” said William J. Shaughnessy M.D., a pediatric orthopedic surgeon at Mayo Clinic’s campus in Rochester, Minnesota. “Safety nets are pretty effective at preventing children from falling off, but in the absence of those, they inevitably do fall.”

Shaughnessy told the Mayo Clinic that even with netting, when a couple of kids are jumping at the same time, one can land on top of the other. He recalled one case of a 14-year-old boy who jumped over the net and broke both of his arms.
