Abstract
A 20-year-old man had a dorsally displaced fracture of the proximal pole of the scaphoid and an ipsilateral palmar lunate dislocation--a rare combination of injuries that has not been previously reported. The most likely pathomechanics of this injury is a sheer fracture of the proximal pole of the scaphoid by the dorsal lip of the distal radius as the injury shifts from a dorsal perilunate to a palmar lunate pattern.
摘要
一名20岁男性患有舟骨近端极背侧移位骨折及同侧掌侧月骨脱位，这是一种罕见的损伤组合，此前未见报道。该损伤最可能的发病机制是，随着损伤从背侧月骨周围型转变为掌侧月骨型，桡骨远端背侧唇缘导致舟骨近端极发生剪切骨折。
