INTRODUCTION: Open reduction and internal fixation 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 fixed by a minimally invasive method. Percutaneous screwing for an anterior column fracture of acetabulum under conventional 2D fluoroscopy is a demanding technique. With fluoroscopic-based computerized navigation, we can determine the position of a screw real time intra-operatively with less exposure to radiation. We proposed that a fluoroscopy-based computerized navigational system would simplify operation procedures. The purpose of this study is to test the application of the fluoroscopy-based computerized navigational system for anterior column fracture of acetabulum.
MATERIALS AND METHODS: A prospective cohort study was conducted. Three patients with mildly displaced or non-displaced anterior column fracture of acetabulum were treated with a retrograde lag screw under a fluoroscopy-based computer navigation system. There were two males and one female with a mean age of 39 years and all patients were followed up for more than 1 year. Patients were allowed to perform joint movement exercises and to walk with partial weightbearing on the first day post-operatively.
RESULTS: The mean operation time was 40 min (range 30-45 min) from the use of fluoroscopy to wound closure and the mean total fluoroscopy time was 38 s (range 35-45 s). Total blood loss was less than 10 ml. The patients were pain free 1 week after the operation and had good functional recovery thereafter. No complication was noted postoperatively.
CONCLUSION: Though the indication for this procedure is limited, we think that there should be potential to apply the screw with less radiation by fluoroscopic-based computerized navigation. Once anatomic reduction can be achieved by the close method in the anterior column fracture of the acetabulum, percutaneous screw fixation under fluoroscopic-based computerized navigation could be a reliable method; however; validating the position of the guide pin and screw by fluoroscopy is suggested.
