Foreign bodies may enter the body by various ways, yet migration in the body seldom occurs. A case is described where a Kirschner wire, which had been inserted in the shoulder joint, migrated through the pleural cavity and the diaphragm, apparently by force of gravity. It was subsequently easily removed by laparotomy.
异物可通过多种途径进入人体，但在体内迁移的情况很少见。本文描述了一例病例，一根曾插入肩关节的克氏针显然在重力作用下穿过胸腔和膈肌发生了迁移。随后通过剖腹手术很容易地将其取出。
