Metallic pins and wires are frequently used for fixation of fractures and dislocations. Migration is one of the potential complications of such fixation methods. Usually, migration of the pins causes only minor complications, but if the device migrates to a vital cavity, serious damage and even death may ensue. The shoulder girdle is one of the areas in which pins and wires are mostly used, the humeral neck fractures being one of them. We report a case in which a Kirschner wire migrated from a subcapital humeral fracture site into the aorta and pericardium, causing sudden cardiac tamponade and death.
金属针和金属丝常用于骨折和脱位的固定。移位是此类固定方法的潜在并发症之一。通常，针的移位仅引起轻微并发症，但如果器械移位至重要腔隙，则可能导致严重损伤甚至死亡。肩胛带是最常使用针和金属丝的部位之一，肱骨头下骨折就是其中之一。我们报告一例克氏针从肱骨头下骨折部位移位至主动脉和心包，导致心脏骤停和死亡的病例。
