Triquetrum fracture

The commonly missed ulnar wrist injury

2nd most common carpal bone fracture (15-18 % of all fractures)

Tender just distal to the ulna

X-ray findings are subtle and frequently missed

In one series, only 20% were visualized on plain film!

When seen, most often on the lateral view

Seen as a chip fracture of unclear donor site

Also, one of my favorite named radiologic findings!

Nonsurgical management is indicated for most triquetral fractures.

Volar splint and follow up with hand surgery.
