Abstract
Carpal injuries are frequently underdiagnosed and underreported injuries of the hand. Scapholunate perilunate dissociation is the most common perilunate instability pattern seen in clinical practice. Transscaphoid, transtriquetral, transcapitate dislocation with a volar intercalated segment instability pattern is a very rare pattern of carpal injury. We describe a case with this unique pattern of injury, explaining its mechanism and treatment. Good outcome can be achieved in these injuries following open reduction and internal fixation with ligamentous repair.
