title: An extraordinary mechanism causing intraoperative migration of the Kirschner-wire.
abstract: Migration of Kirschner wires (K-wires) postoperatively and with use of cannulated implants intraoperatively is a well-known complication. In this article, we present an extraordinary mechanism causing intraoperative migration of a K-wire. A K-wire which was used for temporary fixation of fracture fragments migrated forwardly due to its contact with the drill bit while drilling a hole for a screw. The interaction between the K-wire and the drill bit simulated a gear wheel effect and thus the rotating K-wire advanced. Although no complications occurred in this case, we believe that the mentioned mechanism may be of importance particularly in osteoporotic patients and may cause damage to vital structures.
