Triquetrolunate Dissociation
- Discussion:
- triquetrium is the 3rd most commonly fractured carpal bone;
- ular side of the wrist is supported by
TFC, which articulates w/ both
lunate and the triquetrum;
- Exam:
- lies just distal to
ulnar styloid process, in proximal carpal row;
- to facilitate its palpation, hand must be radially deviated so that
triquetrium moves out from under the
ulnar styloid process;
- triquetrum may be difficult to find, since it also lies under
pisiform;
- Radiographs: 15 deg Reversed Oblique View:
