In this prospective study, we have investigated incidence of injuries of different severity, types of injury, and mechanisms of injury during ice hockey games. All twelve Swedish elite hockey teams were observed during the season 1988-1989 when a total number of 664 games were played. There was a total number of 285
Material and methodsBefore the start of the hockey season 1981-1989, the physicians of all teams of the highest Swedish hockey division (elite league) attended an information meeting concerning the background and purpose of this investigation. The physicans were instructed to record all injuries on a special card5 and to send these cards to one of the authors (YT). Thus, clinical examination and registration were always performed by the team physicans. Attendence records for practice sessions and games were, in most teams, kept by the assistant coach.Most Swedish elite players are subsidized amateurs having a half-time appointment in addition to ice hockey.Injury was defined as any injury occurring during ice practices or games and causing the player to stop playing or to miss the next practice session or game5 16. Facial lacerations, which are common in ice hockey, but do not cause absence from practice or games, are also reported.Injuries were classified as traumatic or over-use injuries. In the latter category there was an often insidious and gradually increasing intensity of discomfort, but no obvious trauma. Injuries were also classified into three categories of severity: minor (an absence from practice of less than 7 days), moderate (an absence of 8 to 30 days), and major (an absence of over 30 days). Return to participation in practice or game after an injury was determined by the team physicians.There were 12 teams in the highest Swedish hockey division. These teams played a total of 664 games. For purposes of calculating the incidence of injury during games, six players were assumed to be on the ice at any one time, making a total of 3984 player-game hours.
ResultsThere was a total of 285 injuries. These 285 injuries occurred at 267 occasions; at 18 times one player had two injuries at one and the same time. As for severity, 174 (61.1%) injuries were classified as minor, 66 (22.3%) were moderate, and 25 (8.8%) were major. In 20 cases, the severity of the injury has not been possible to establish. One player was permanently severely disabled and became tetraplegic due to a fracture-dislocation of the cervical spine. Two players had to terminate their career with chronic knee instability and disabling multidirectional shoulder instability respectively.Of the total 285 injuries, 211 (74.0%) occurred during games and 74 (26.0%) during practice. For the individual player, the incidence of injury was 53.0 per Br J Sp Med 1991; 25(2) 87
