Background: Neck lacerations sustained while playing ice hockey are rare but potentially fatal. Neck laceration protectors (NLPs) have been around for decades but only lately are becoming required by leagues given recent fatalities. Purpose: To outline the relevant neck anatomy at risk, describe rink-side evaluation and management techniques, review historical and contemporary NLP mandates, and conclude with evidence-based recommendations. Study Design: Narrative review; Level of evidence, 5. Methods: A review of the literature regarding neck lacerations in ice hockey was utilized for content collection. Google Scholar and PubMed were queried for peer-reviewed articles relevant to the topic. Keywords including “ice hockey,” “neck lacerations,” “neck laceration protector,” and combinations thereof were used to identify relevant literature. Results: Neck lacerations are rare but can be fatal given that they often damage zone II neurovascular structures. While numerous international leagues require mandates for NLPs, notable holdouts include the National Hockey League and the National Collegiate Athletic Association. Numerous materials and builds for NLPs are capable of withstanding penetration from a skate slash, although they possess differences in comfort and neck range of motion. Conclusion: NLPs have the capacity to prevent significant and potentially fatal laceration injuries in ice hockey. Based on the available data, implementing NLP mandates appears to be in the interest of player safety.

ImportanceNational Hockey League (NHL) players are exposed to frequent head trauma. The long-term consequences of repetitive brain injury, especially for players who frequently engage in fighting, remains unknown.ObjectiveTo investigate the mortality rates and causes of death among NHL enforcers with more career fights and penalty minutes as compared with matched controls.Design, Setting, and ParticipantsThis matched cohort study examined 6039 NHL players who participated in at least 1 game in the seasons between October 11, 1967, and April 29, 2022, using official NHL data. Cohorts designated as enforcer-fighter (E-F) and enforcer-penalties (E-P) were selected. The E-F cohort consisted of players who participated in 50 or more career fights (n = 331). The E-P cohort included players with 3 or more penalty minutes per game (n = 183). Control-matched NHL players were identified for each E-F player (control-fighter [C-F]) (n = 331) and each E-P player (control-penalties [C-P]) (n = 183).ExposuresFighting and penalty minutes were both used as proxies for head trauma exposure. Players with significantly increased exposure to fighting and penalties (E-F and E-P cohorts) were compared with NHL players with less frequent exposure to head trauma (C-F and C-P cohorts).Main Outcomes and MeasuresMortality rates and age at death of the enforcer and control cohorts, and their causes of death using data obtained from publicly available sources such as online and national news sources, including NHL.com.ResultsAmong the 6039 NHL players identified (mean [SD] age, 47.1 [15.2] years), the mean (SD) number of fights was 9.7 (24.5). The mortality rates of E-F and C-F players (13 [3.9%] vs 14 [4.2%], respectively; P = .84) or E-P and C-P players (13 [7.1.%] vs 10 [5.5%]; P = .34) were not significantly different. The mean (SD) age at death was 10 years younger for E-F players (47.5 [13.8] years) and E-P players (45.2 [10.5] years) compared with C-F players (57.5 [7.1] years) and C-P players (55.2 [8.4] years). There was a difference in causes of death between the control and enforcer players (2 neurodegenerative disorders, 2 drug overdoses, 3 suicides, and 4 vehicular crashes among enforcers vs 1 motor vehicle crash among controls; P = .03), with enforcers dying at higher rates of overdose (2 of 21 [9.5%] vs 0 of 24) and suicide (3 of 21 [14.3%] vs 0 of 24) (P = .02).Conclusions and RelevanceThe findings of this matched cohort study indicate that there is no difference in overall mortality rates between NHL enforcers and controls. However, being an enforcer was associated with dying approximately 10 years earlier and more frequently of suicide and drug overdose.
