K-wire migration to unexpected site

We reported a migration of forgotten wire to contra lateral region presented as corpus alienum of the lung in a 34-year-old woman after distal clavicular fracture surgery three years previously. We also reported a migrating wire fragment after a fall accident in sport activity of a 28-year-old male; which travelled from clavicular region to cervical 6-7 region in 4 days. Both cases were successfully managed without extravagant surgery or serious damage, helped by meticulous history taking, physical examination, precise imaging, and prompt management. These cases render lessons and discussion for further understanding of the wire migration and the exact protocol in handling K-wire patient.
