Difficulty identifying Triquetrum fracture on plain radiograph
Difficulty identifying Triquetrum fracture on plain radiograph
The difficulty of identifying a fracture of the triquetrum using standard anterior-posterior radiographs of the wrist is apparent in this image, in which the superimposed shadow of the pisiform obscures the fracture. Note the small density (arrow) near the ulnar styloid which could represent a fracture fragment or a possible concomitant lunate fracture.
