Percutaneous antegrade screwing for anterior column fracture of acetabulum with fluoroscopic-based computerized navigation.

Introduction Open reduction and internal Wxation has been the gold standard for displaced fracture involving weightbearing dome and fractures with intra-articular fragments. However, extensile exposure can lead to complications. Fracture with minimal displacement can be Wxed by a minimally invasive method. Percutaneous screwing for an anterior column fracture of acetabulum under conventional 2D Xuoroscopy is a demanding technique. With Xuoroscopic-based computerized navigation, we can determine the position of a screw real time intra-operatively with less exposure to radiation. We proposed that a Xuoroscopybased computerized navigational system would simplify operation procedures. The purpose of this study is to test the application of the Xuoroscopy-based computerized navigational system for anterior column fracture of acetabulum.
