Concussions in the NHL: A narrative review of the literature.

Izraelski, J. , 2014

Ice hockey has been identified as a sport with a high risk for concussions. Given the health sequelae associated with the injury, a great deal of attention has been placed on its diagnosis, management and return-to-play protocols. The highest level of ice hockey in North America is played in the National Hockey League (NHL), and concussions pose a serious threat to the health of the players and the game itself. Unfortunately, the scientific literature on concussions in ice hockey is derived mostly from research conducted on youth and amateur levels of play, leaving a gap in our knowledge at the professional level. This narrative review attempts to summarize what is known about concussion incidence, mechanisms of injury and risk factors in the NHL.

Economic burden of time lost due to injury in NHL hockey players.

Economic burden of time lost due to injury in NHL hockey players.

Donaldson, L., et al , 2014

Players in the National Hockey League (NHL) are often sidelined by injuries, including concussion. The acute, intermediate and long-term effects of repetitive head trauma remain a concern of many. In 1997, the NHL and NHL Players Association established the NHL-NHL Players Association Concussion Program to diagnose, assess and treat concussion via a standardized and scientific approach. Documenting and analyzing the trends, incidence and underlying mechanisms of concussion may help in devising future prevention and treatment plans for concussion in hockey in general and the NHL in particular. The purpose of this study, therefore, was to systematically review and summarize the existing published literature on the trends, incidence rates and underlying mechanisms of concussion in the NHL.

The epidemiology of professional ice hockey injuries: A prospective report of six NHL seasons.

McKay, C. D., et al, 2012

BACKGROUND:

There is a paucity of literature examining injury and illness rates in men's professional ice hockey. This study aimed to determine injury and illness rates in the NHL over six seasons, and identify predictors of injury-related time loss in this population.

METHODS:

This study involved an inclusive cohort of hockey players from all NHL teams competing in the 2006-2007 through 2011-2012 seasons. A standardised electronic injury surveillance system was used to report injury and illness events. The primary outcome was regular season and postseason time-loss injury/illness. The secondary outcome was man-games lost from the competition.

RESULTS:

On the basis of the estimated athlete exposures (AEs), the overall regular season incidence density was 15.6 injuries/1000 AEs and 0.7 illnesses/1000 AEs. Based on recorded time on ice, the injury rates were roughly threefold higher at 49.4 injuries/1000 player game-hours and 2.4 illnesses/1000 player game-hours. There was a reduction in injury rates over the 6-year period, with the greatest reduction between the 2007-2008 and 2008-2009 seasons. Multivariate predictors of time loss greater than 10 days were being a goalie (OR=1.68, 95% CI 1.18 to 2.38), being injured in a road game (OR=1.43, 95% CI 1.25 to 1.63) and the mechanism of injury being a body check (OR=2.21, 95% CI 1.86 to 2.62).

CONCLUSIONS:

There was an overall reduction in the time-loss injury and illness rates over six seasons. Being a goaltender, being injured on the road and being injured by a body check were therisk factors for time loss greater than five 'man games'.

In-game fatigue influences concussions in national hockey league players.

In-game fatigue influences concussions in national hockey league players.

Stevens, S. T.,et al , 2008

The number of concussions and other head injuries are increasing in the National Hockey League (NHL). The factors that may influence concussion risk in hockey remain largely unknown. In the current study, data on 787 NHL players from the 2001-2002 season were examined. It was found that a player's average ice time per game was a significant predictor of concussion. A player's total ice time for the season was not a significant predictor, however, and there was no significant difference found in the number of games played in the season between those who suffered a concussion and those who did not. These data suggest that in-game fatigue is an important factor when considering concussions.

Sports hernia in national hockey league players: Does surgery affect performance?

Sports hernia in national hockey league players: Does surgery affect performance?

Jakoi, A., et al, 2008

Background: 

Athletic pubalgia is a complex injury that results in loss of play in competitive athletes, especially hockey players. The number of reported sports hernias has been increasing, and the importance of their management is vital. There are no studies reporting whether athletes can return to play at preinjury levels.

Purpose: 

The focus of this study was to evaluate the productivity of professional hockey players before an established athletic pubalgia diagnosis contrasted with the productivity after sports hernia repair.

Study Design: 

Cohort study; Level of evidence, 3.

Methods: 

Professional National Hockey League (NHL) players who were reported to have a sports hernia and who underwent surgery from 2001 to 2008 were identified. Statistics were gathered on the players’ previous 2 full seasons and compared with the statistics 2 full seasons after surgery. Data concerning games played, goals, average time on ice, time of productivity, and assists were gathered. Players were divided into 3 groups: group A incorporated all players, group B were players with 6 or fewer seasons of play, and group C consisted of players with 7 or more seasons of play. A control group was chosen to compare player deterioration or improvement over a career; each player selected for the study had a corresponding control player with the same tenure in his career and position during the same years.

Results: 

Forty-three hockey players were identified to have had sports hernia repairs from 2001 to 2008; ultimately, 80% would return to play 2 or more full seasons. Group A had statistically significant decreases in games played, goals scored, and assists. Versus the control group, the decreases in games played and assists were supported. Statistical analysis showed significant decreases in games played, goals scored, assists, and average time on ice the following 2 seasons in group C, which was also seen in comparison with the control group. Group B (16 players) showed only statistical significance in games played versus the control group.

Conclusion: 

Players who undergo sports hernia surgeries return to play and often perform similar to their presurgery level. Players with over 7 full seasons return but with significant decreases in their overall performance levels. Less veteran players were able to return to play without any statistical decrease in performance and are likely the best candidates for repair once incurring injury.

NHL trainers search for answers to solve problem of groin injuries.

NHL trainers search for answers to solve problem of groin injuries.

Carlson, M., 2006

Hearing news of John Collins’ departure as NHL chief operating officer may not raise the eyebrow of every casual fan prepping a backyard rink. But it should. Especially since Collins, the league’s third in command, is the brain behind the Winter Classic.

Collins, who turns 54 this week, has been with the NHL since 2006. He took over as COO in 2008. He was the driving force for only the Winter Classic, but also the wildly successful HBO 24/7 series, which he shepherded along with producer Ross Greenburg. Collins is largely responsible for the Stadium Series and the league’s national television deals in Canada and the U.S. The league has grown significantly in popularity under his’ guidance.

“John leaves a lasting mark,” commissioner Gary Bettman told NHL.com. “His energy, creativity and skill at building strategic partnerships helped drive significant revenue growth for our league. We are grateful for his many contributions and wish him the best in his new endeavors.”

Added Collins to NHL.com: “I’m grateful to commissioner Bettman for his leadership and friendship over the past nine years. He had a vision for extending the reach of the NHL and supported us completely as we set out to make the game as big as it deserves to be. The NHL’s future is filled with promise and potential and I will admire and cheer the League’s successes to come on the global stage.”

Collins, who worked in the NFL before the NHL, is leaving to pursue another business opportunity. His departure is effective Dec. 4, per Sportsnet’s John Shannon.
