[A classification proposal for compression-flexion articular fractures of the distal extremity of the radius. A radiographic study of 40 cases].

40 articular fractures of the distal radius with palmar displacement, have been analyzed with Roentnograms. An original classification is proposed for a better initial evaluation of detailed articular damages and displacement. 4 main different types of fracture are described considering for elementary fragments constituted with antero-medial margin, radial styloid and dorsal margin; type A: total anterior margin, type B: separated anterior margin, type C: antero-lateral margin, and type D: antero-medial margin. The two types I and II described by Cauchoix, Duparc and Postel concerning the integrity of the dorsal margin have been incorporated. The quantity of radial gene fractured is determined on lateral view: < 1/2, > or = 1/2, and total. Finally the displacement is typed: anterior dislocation, or anterior translation. An original case of volar dislocated fracture with an intact radial styloid is reported. This classification could drive to specific orientations for treatment: even external fixation often associated with pinning, or alternative buttress plating.
