K-wire Migration Following Acromioclavicular Joint Fixation: A Case Report.

Kirschner wire (K-wire) is commonly used for temporary fixation of bone fractures, particularly in pediatric patients, but it poses risks such as breakage and migration. We present the case of a 67-year-old patient who underwent acromioclavicular joint fixation with K-wires after an injury. Nine months post-surgery, a wire fragment was found to have broken and migrated to the neck area. The migration led to the development of a pseudoaneurysm, which required surgical intervention for removal. The wire fragment was successfully removed, and the aneurysm was repaired after rupture. This case highlights the risks associated with wire migration and underscores the importance of strict adherence to the Tension Band Wiring (TBW) technique. Timely removal of fixation devices and regular radiographic monitoring during follow-up are essential to prevent potentially life-threatening complications.
