"AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...

(b) Initial "scaphoid" view was negative. (c) Followup anteroposterior radiographs, 12 days later, shows obvious scaphoid fracture (arrows). [1] Triquetral fracture usually occurs on the dorsal aspect by impingement from the ulnar styloid or avulsion of strong ligamentous attachment.
