Abstract We describe an unusual case of trans-scaphoid perilunate injury where the proximal half of the scaphoid avulsed from all attaching ligaments and extruded into the forearm. Treatment involved anatomic reduction and internal fixation of the fracture, scapholunate (SL) ligament repair, temporary K-wire fixation, and prolonged immobilization. At 19-month follow-up, the fracture healed, SL ligament remained intact, and the patient recovered much of his hand function.
