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.
我们报告一例同时发生的同侧关节内第二掌骨头、关节内第四掌骨基底和尺骨茎突骨折。这些骨折是由冰球比赛中拳头受到打击的特殊情况引起的；手在握住球杆时受到撞击。这些骨折的特定组合此前在文献中尚未有报道。在该事件中，轴向压缩力从第二和第四掌骨头传递，跳过第三掌骨头，通过腕掌关节和腕骨传至腕部尺侧。由于每个骨折仅表现出轻微移位，我们采用保守治疗，效果良好。
