[Successful cardiac surgical removal of migrated Kirschner wires used for fixation of the surgical neck of the humerus].

Dislocation and migration of two Kirschner wires were found 13 days after fixation of the surgical neck of the humerus. One of the wires was located between the lateral thoracic muscles, while the other one has perforated the apex of the heart, showing a synchronous motion with heart contractions. An anterolateral thoracotomy was performed and the wires were removed successfully.
