Prevention of malunions in the rotation of complex fractures of the distalfemur treated using the Dynamic Condylar Screw (DCS): An anatomical graphic analysis using computed tomography on cadaveric specimens

The AO ASIF dynamic condylar screw is a popular method for the treatment of severe distal femoral fractures. Two methods of application have been pres ented by the AO group, one In the AO manual and the other in the teaching v ideo tapes. The small difference in the techniques suggested that one of th ese methods might present a risk of rotational malunion in cases of severe comminuted fractures. The question of determining which method was less app ropriate was investigated on human cadaveric specimens using a graphic anal ysis of computed tomograms. We found disadvantages for both methods and propose a third method combinin g the advantages of the two original methods.
