Trampoline Park and Home Trampoline Injuries

Abstract

BACKGROUND AND OBJECTIVE: Trampoline parks, indoor recreational facilities with wall-to-wall trampolines, are increasing in number and popularity. The objective was to identify trends in emergency department visits for trampoline park injuries (TPIs) and compare TPI characteristics with home trampoline injuries (HTIs). METHODS: Data on trampoline injuries from the National Electronic Injury Surveillance System from 2010 to 2014 were analyzed. Sample weights were applied to estimate yearly national injury trends; unweighted cases were used for comparison of injury patterns. RESULTS: Estimated US emergency department visits for TPI increased significantly, from 581 in 2010 to 6932 in 2014 (P = .045), whereas HTIs did not increase (P = .13). Patients with TPI (n = 330) were older than patients with HTI (n = 7933) (mean 13.3 vs 9.5 years, respectively, P < .001) and predominantly male. Sprains and fractures were the most common injuries at trampoline parks and homes. Compared with HTIs, TPIs were less likely to involve head injury (odds ratio [OR] 0.64; 95% confidence interval [CI], 0.46–0.89), more likely to involve lower extremity injury (OR 2.39; 95% CI, 1.91–2.98), more likely to be a dislocation (OR 2.12; 95% CI, 1.10–4.09), and more likely to warrant admission (OR 1.76; 95% CI, 1.19–2.61). TPIs necessitating hospital admission included open fractures and spinal cord injuries. TPI mechanisms included falls, contact with other jumpers, and flips. CONCLUSIONS: TPI patterns differed significantly from HTIs. TPIs are an emerging concern; additional investigation and strategies are needed to prevent injury at trampoline parks.
