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.
