A. Brandser, B. T. Ellingson] Background: The term "boxer's fracture” has been used to describe fractures to the fifth metacarpal. In fact, boxers do not fracture their fifth metacarpal but their second or third metacarpals. Methods: We reviewed demographic data for 51 patients with boxer's fractures. Sex, age, hand involved, hand dominance, method of injury, ethanol intoxication, and presence of anger at the time of injury were evaluated. Results: Only 18 % of our cases involved a patient hitting another person. Fifty-one percent of the cases occurred when the patient intentionally struck a hard object. Thirty-one percent of fractures were accidental or due to crush injury. Of those injured from an intentional blow, nearly all of the patients were male. Patients were commonly angry at the time of injury. Conclusions: Based on the characteristics of our patients with these fractures, we believe a more appropriate name for this injury is the MACHO fracture (Men Angrily Cuffing Hard Objects).
