Injuries to the Upper Extremity in Ice Hockey

BACKGROUND: Injuries to the upper extremity are common in ice hockey. PURPOSE: To investigate the mechanisms, types, and severity of upper extremity ice hockey injuries in patients in different age categories. STUDY DESIGN: Retrospective cohort study. METHODS: We analyzed 760 consecutive upper extremity injuries in Finnish ice hockey players reported to an insurance company during 1996. RESULTS: The overall injury rate of upper extremity injuries was 14.8 per 1000 player-years; 70% occurred during games. Of the 861 injury types, 32% were contusions, 28% sprains or strains, and 27% fractures. Checking or other collisions with players caused 76% of the injuries to the shoulder (170 of 223), 55% of the injuries to the elbow (35 of 64), and 45% of the injuries to the distal extremity (213 of 473). Of the 561 injuries with known severity, 38% were major. The injury risk increased significantly with age, from players younger than 12 years to players 25 to 29 years of age. The injury profile among 15- to 19-year-old players was similar to that of adult players. CONCLUSIONS: Injuries to the upper extremity are relatively serious because of the high number of shoulder injuries and fractures. The frequency of injuries increased with age. A considerable proportion of upper extremity injuries was caused by body checking.
