BACKGROUND: During scaphoid fixation, a pin guide is first inserted along the axis of the scaphoid, and then a cannulated screw is inserted around the pin guide. At least, the pinguide is removed. To verify the position of the pin guide, fluoroscopy is typically used, with the disadvantage of irradiation. Thus, it is impossible to visualize the pin guide in more than one view simultaneously. The goal of this study was to compare two pin guide placement techniques in scaphoid fixation: conventional (CF) vs. fluoroscopic navigation (FN). METHODS: Eleven upper limbs of cadavers were divided into two groups. The CF group included four scaphoids which were to be fixed with pin guide. The FN group included seven scaphoids which were to be fixed with the same technique under FN. RESULTS: The accuracy of screw insertion in both groups does not differ. In the CF group, the X-ray exposure time is four times higher. The total duration of the surgical procedure is slightly higher in the FN group. CONCLUSIONS: We are of the opinion that FN could be applied in clinical practice and could offer significant benefits in the treatment of fixation of the scaphoid. (c) 2008 John Wiley & Sons, Ltd.
