Fixation of comminuted, articular fracture fragments is frequently difficult. This can be accomplished with Kirschner wires (K-wires), but the risk of migration of smooth K-wires is well known. A case of migration of such a wire from the acetabulum, through the great vessels, and into the heart is presented. The Herbert screw is designed to be "buried" and, thus, allows firm fixation and congruent reduction of overlying fragments. The variation in thread pitch between the two ends of the Herbert screw should prevent migration once the screw is seated. A use of the Herbert screw in the fixation of articular fracture fragments in acetabular reconstruction is presented.
