Pronated Grip View With Wrist Deviation: A Pilot Study on the Effect on Ulnocarpal Relationships

We hypothesize that different positions of the wrist in the coronal plane makes the carpus susceptible to ulnar impaction.We prospectively enrolled 10 adult volunteers and obtained fluoroscopic images of each wrist in 12 different positions using a standardized protocol. Distances from the ulna to the lunate (UL) and ulna to the triquetrum (UT) were digitally measured as was the portion of the lunate surface area that was uncovered (LUR) with...
