Lunotriquetral coalition

Discussion:

Carpal coalitions are rareThe luno-triquetral coalition is the most common followed by capito-hamate. It is generally asymptomatic especially when the coalition is osseous, as is it in this case.

Positive ulnar variance describes where the distal articular surface of the ulna is more distal as compared to the articular surface of the radius. It is associated with ulnar impaction syndrome and triangular fibrocartilage tears.
