The daily educational pearl – triquetrum fracture / dislocation

Triquetrum fracture / dislocation

or carpal ligamentous injury stage III – stage II injury + dislocated triquetrum; can be associated with a volar triquetral fracture

– best seen on lateral views; the avulsion fragment is usually found on the dorsal surface

Isolated fractures are managed in ED with a wrist splint (generally 2 weeks for avulsion fractures, 6 weeks for undisplaced body fractures). They need Orthopaedics follow-up within 1 – 2 weeks.

Displaced body fractures (>1 mm), open fractures or those associated with perilunate dislocation need urgent Orthopaedics referral.
