The distribution of injuries in men's Canada West university football. A 5-year analysis

We conducted a prospective cohort study from 1993 to 1997 to determine the frequency and severity of injury in men's Canada West university football. The Canadian Intercollegiate Sport Injury Registry was used to document baseline preseason data, daily athlete participation, and subsequent injury from five varsity football teams. An injury was defined as "any injury resulting in one or more complete or partial sessions of time loss" or "any concussion or transient neck neurologic injury." The annual proportion of injured athletes ranged from 53.5% to 60.4%, with a 5-year total of 1,811 injuries. Regression analysis indicated that the rate of nonconcussion, nonneck neurologic injuries increased. Concussion (N = 110), hamstring strain (N = 88), and brachial plexus (N = 84) injuries were the most common, specific injury diagnoses. Knee injuries resulted in the highest rate of severe (greater than or equal to 7 sessions of time loss) injury and resulted in the most time loss (3,350.5 sessions). Ligament sprains and muscle strains and spasms accounted for approximately half of all injury diagnoses. A total of 1,173 injuries (65%) were related to contact between players or between players and other obstacles. Future studies should be conducted to identify risk factors for the ultimate purpose of implementing injury prevention strategies.

Skiing and snowboarding injuries in the children and adolescents of Southern Alberta

OBJECTIVE

To identify injuries and profile the characteristics of injured skiers and snowboarders younger than 18 years of age in Southern Alberta, Canada.

DESIGN

Case-series over one year.

PARTICIPANTS

Injured skiers and snowboarders younger than 18 years of age presenting to the ski patrol members at each of seven ski areas in Southern Alberta.

MAIN OUTCOME MEASURES

Information on injured individuals reporting to the ski patrol at the involved areas was documented on a standardized injury reporting form. Anonymous information was then copied and sent to the University of Calgary Sport Medicine Centre, where the data were analyzed. Proportions of injured skiers and snowboarders with specific characteristics or participating in specific environmental conditions are presented.

RESULTS

There were a total of 832 (60.0%) injury reports filed for skiers and 557 (40.1%) for snowboarders, reflecting 1,635 separate injuries. Head injuries were the most frequently reported (19.1% of all regional injuries). The most commonly injured region was the knee among skiers (n = 213; 22.8%) and the wrist among snowboarders (n = 173; 27.8%). Lower extremity injuries in skiers and upper extremity injuries in snowboarders were most common. Younger male skiers and snowboarders reported high proportions of head, neck, and back injuries.

CONCLUSION

The lower extremity in skiers and the upper extremity in snowboarders were most susceptible to injury. A cause for concern is the high proportion of head injuries reported for both male skiers and snowboarders of younger age groups. Further study into protective equipment design and function is required.
