The aim of this study was to compare the efficiency of dorsal tangential fluoroscopy and ultrasonography in detecting dorsal screw penetration in distal radius volar locking plate applications. Ten cadaveric forearms were operated. The distal four screws were protruded 0, 1 and 2?mm into each of the second, third and fourth dorsal compartments of distal radius. Dorsal horizon views were taken using fluoroscopy. Each radiographic image was evaluated by two orthopedic surgeons who are blinded to procedure. Sonographic evaluations were performed by an orthopedic surgeon blinded to the procedure. Both dorsal horizon view and ultrasonography assessments were noted by the evaluators whether the tip of the screw penetrated or not the dorsal cortex for each compartment. No significant difference was observed on correct detection of 0?mm, 1?mm and 2?mm screw penetrations at second and third compartments. In the fourth compartment, there was no difference with 0?mm and 2?mm penetrations but correct detection accuracy of 1?mm screw penetration was 87% in ultrasonography group and 71% in dorsal horizon view group. The accuracy of ultrasonography on 1?mm penetration at the fourth compartment is better than dorsal horizon view. However, dorsal horizon view and ultrasonography accuracy is similar for the other compartments and penetration levels. Ultrasonography is a reliable and effective procedure for detection of dorsal screw penetrations. Level III, Diagnostic study.
