Intrathoracic migration of Steinmann pins

Kirschner wire migration from subcapital humeral fracture site, causing hydropneumothorax

Migration of wires or pins around the shoulder is a known complication, though their migration within the chest is uncommon. We report an unusual case of hydropneumothorax due to migration of a bent Kirschner wire from the right proximal humerus in a 63 year-old man. We reviewed his clinical history, physical examination, imaging findings, surgical method and outcome. We also reviewed the literature on orthopaedic wire migration and latest technique in removal of the wires. Chest radiographs and chest computerized tomography are useful in detection and diagnosis of this disorder. Regular radiographic follow-up is needed for patients with internal fixation devices; any fractured or migrated pins or wires must be removed immediately to prevent dangerous complications. It is always important to remove the wires at the end of the treatment. Early removal of fixation wires and regular follow-up if wires are retained are essential to prevent serious complications.

Endopelvic migration of a sternoclavicular K-wire. Case report and review of literature

We report a unique case, never before published, of sternoclavicular joint fixation K-wire migration to the pelvic region, in a 56 year-old man. Two years previously, sternoclavicular dislocation had been fixed by three wires. A transitory episode of precordial thoracic pain followed by iterative abdominal pain accompanied the migration. Extraction was performed five years later. Scapular K-wire migration is frequent. The proximity of cardiovascular structures may have fatal consequences. This type of internal fixation raises questions, and migration prevention needs to be taken into account. Medical complications and the legal context are major factors leading us to abandon this type of osteosynthesis. Once migration has been diagnosed, the wire should be removed without delay.

Migration of a Kirschner wire used in the fixation of a subcapital humeral fracture, causing cardiac tamponade: case report and review of literature

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.

Metallic foreign body in the lung: a case report

We present the case of an 11-year-old girl with a history of needle ingestion. Radiological investigations revealed that the foreign body had migrated into the lung parenchyma. We report the use of fluoroscopy and thoracoscopy to aid localization and facilitate removal of a metallic foreign body in the thorax.
