title: Triple Fracture of the Intra-Articular Second Metacarpal Head, Intra-Articular Fourth Metacarpal Base, and Ulnar Styloid of An Ice Hockey Player: A Case Report.
abstract: We present a case of simultaneous ipsilateral fractures at the intra-articular second metacarpal head, intra-articular fourth metacarpal base, and ulnar styloid. These fractures were caused by the peculiar condition of a blow to the fist during an ice hockey game; the hand was struck while it was gripping a stick. The specific combination of these fractures has not been previously reported in the literature. In this incident, axial compression force was transmitted from the second and fourth metacarpal heads while skipping the third metacarpal head to the ulnar side of the wrist via the carpometacarpal joints and carpal bones. Because each fracture exhibited only slight displacement, we used conservative treatment with good outcomes.
