[Wrist X ray for analysis of the articular surface of distal radius].

Abstract

In the distal radius fracture requires radiographic views that allow you to see the articular surface without interposition. The objective was to determine whether lateral radiographic projections 7 and 22° improve the analysis of this surface. METHOD Case series study with radiographs of healthy and operated patients, in order to identify the lunate and scaphoid facets in lateral and anteroposterior projections. Qualitative analysis was made on the radiographs of the distal radius with wedges of 7 and 22° in the lateral views and 11° in the anteroposterior view. RESULTS There were evaluated 14 radiographs of the distal radius of healthy volunteers and 10 patients with distal radius fractures who recieved surgery with internal fixation, and also two anatomical models. In 14 healthy and 10 patients, it was found that the views at 7 and 22° can be better appreciated radio lunate and radio scaphoid surface respectively, observing images with less overlapping in the radiograph of 22° in both groups. DISCUSSION Radiographic views are important to determine the immediate results of fixation on a distal radius fracture. We observe that the lateral view at 7° is better to show the screws on the lunate facet of the radius. The lateral view at 22° is better to show the facet of the radius with the scaphoid. Finally, the anteroposterior projection at 11° allows us to see the radio carpal joint with lower image overlay.
