[Unusual complication of osteosynthesis].

Intrathoracic and intravascular migratory foreign bodies are a small but distinctive subgroup of injuries. The intravascular embolus can be treated like arterial or venous emboli of any other sort and removed as indicated. Wandering foreign bodies in the body cavities should be removed when they need to be, just like bodies imbedded in the body in a fixed position. Authors report an unusual case of migratory foreign body as a complication of osteosynthesis.
