[Intra-abdominal migration of a Kirschner wire from the femoral neck]

A epiphysiolysis capitis femoris in a child was treated bei Kirschner-wire fixation. Postoperatively one of these wires broke and presumably migrated through the acetabulum intraperitoneally into the true pelvis. The Kirschner-wire fragment was removed by laparotomy. We discuss the technique of application of Kirschner-wires and complications of the procedure, in particular migration and dislocation.
