Sex- and Sport-Specific Epidemiology of Cervical Spine Injuries Sustained During Sporting Activities.

Background: Although several investigations have examined the epidemiology of cervical spine injuries in sports, few studies have analyzed the nationwide incidence and sex-specific epidemiology of cervical spine injuries.

Method: The National Electronic Injury Surveillance System database, which collects information on patients presenting to the emergency department at 100 hospitals across the United States, was queried for neck sprains and cervical fractures associated with sporting activities from 2000-2015.

Result: A total of 26,380 neck sprains and 1166 fractures were identified. Compared with females, the incidence for injuries in males was 1.7 times greater for neck sprains and 3.6 times greater for fractures (P < 0.0001). Football was the most common cause of cervical sprains in males, followed by cycling and weightlifting/aerobics. Females sustained most neck sprains in weightlifting/aerobics, trampoline, and cheerleading. From 2000 to 2015, the incidence of neck sprains from aerobics increased from 15.5 to 25.3 per million person-years (P < 0.0001). Similarly, the incidence of cervical fractures from cycling increased from 0.67 to 2.7 per million (P < 0.0001). For males, cycling was the most common cause of fracture, followed by diving/swimming and football. For females, horseback riding was most common, followed by cycling and diving/swimming.

Conclusions: Football is the leading cause of cervical sprains in the United States. The most common cause of cervical fracture in men is cycling, while in women it is horseback riding. The incidence of sport-related cervical fractures has increased by 35% from 2000 to 2015, which has been driven by an increase in cycling-related injuries.
