Understanding the Injury Mechanism in Hamate Hook Fractures by Investigating Fracture Morphologies: A Case Series Study.

Our results question the theory that most hamate hook fractures in athletes are caused by direct force exerted on the palm because the fracture morphology was different from that of patients injured by acute trauma from direct force. Instead, these fractures likely stem from an indirect mechanism involving repetitive force generated by the tendons and muscles acting on the hook.
