The incidence of boxing-related upper-extremity (UE) injuries in the United States has not been well characterized. Recent rule changes have been made to make participation safer for athletes, although the consequences of such rule changes on injury rates is unclear. Therefore, we sought to determine the incidence, characteristics, and trends of boxing-related UE injuries. ⋯ Injuries to the UE due to participation in boxing accounted for thousands of emergency department visits in the United States annually, with males younger than 20 years of age, most susceptible to injury. Injuries to the hand, wrist and shoulder occurred at the highest rate. Finally, following rule changes made by sanctioning organizations in 2013, a significant decline in boxing-related UE injuries were observed.

The management of concussion in pediatric patients has always been guided by treatment guidelines that have been drawn from consensus statements rather than clinical research projects. Grool and colleagues conducted a clinical research project on an early return to physical activity and its effect on post-concussion symptoms. The study enrolled 3063 pediatric patients, age 5.0 to 17.99 years of age who presented to one of nine Pediatric Emergency Research Centers in Canada. 2413 patients completed the primary outcome for exposure. ⋯ Early return to physical activity was associated with a lower risk of Persistent Post-Concussive Syndrome (PPCS) than in patients reporting no physical activity at 28 days (24.6% vs. 43.5%, Absolute risk difference, (ARD), 18.9% (95% CI 14.7-23.0%). Among the sub-group of patients who were symptomatic at day 28 (n = 803), PPCS was more present in the patients that reported no physical activity, (n = 584: PPCS 52.9%), than those with light aerobic activity (n = 494 [46.4%; ARD, 6.5%; 95% CI 5.7-12.5%], moderate activity [n = 176 (38.6%; ARD, 14.3%; 95% CI 5.9%-22.2%], or full contact activity [n = 133 (36.1%; ARD, 16.8%; 95% CI 7.5%- 25.5%]. Therefore, in patients aged 5 to 18 years with acute concussion, a return to physical activity within 7 days of acute injury was associated with less symptoms at 28 days than in patients who had a period of prolonged rest rather than an early return to physical activity.
