Head and neck injuries were most common (33.3% of injuries), followed by upper extremity (31.3%), trunk (18.8%), lower extremity (14.6%), and physiologic injuries (2.1%). The most common type of injury was ligament sprain (25.0%); followed by concussion (14.6%), hematoma\/contusion (12.5%), muscle strain (10.4%), and abrasion (8.3%). Tackling was the most common mechanism of injury (74.5%). Males were injured at a significantly higher rate than females (RR, 7.5, P &lt; .01), but no significant difference was observed based on player position ( P = .08).<\/jats:p>\n

Relevance: Understanding injury patterns in an American rugby union will be important for formulating future injury prevention, assessment, and treatment
