Migration of a Kirschner wire from the clavicle into the intrathoracic trachea.

We report a 70-year-old man who had a rare complication related to the insertion of Kirschner wires for fixation of a right clavicle fracture. Eight months after the placement of the Kirschner wires, he presented with cough and hemosputum. Chest roentgenograms, chest computed tomographic scans, and bronchoscopy revealed that one of the Kirschner wires had migrated through the lung and into the intrathoracic trachea. Immediate thoracotomy was performed to remove the wire. His postoperative course was uneventful.
