Answer
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.
