Unusual combined fracture dislocation of the wrist and metacarpophalangeal joints： a case report and review of the literature

Volar perilunate fracture dislocation is an extremely rare carpal injury, but associated with metacarpophalangeal joint dislocation of both the ipsilateral index and middle finger has never been reported. We report one case of a 28-year-old man following a high-energy trauma. After performing closed reduction of the metacarpophalangeal joint injury, open reduction of the wrist injury through volar approach was done, and a K-wire fixation was used to stabilize the scaphoid fracture and lunotriquetral joint. After a 16 months＇ follow-up period, the wrist regained a full range of motion without symptoms, and the fractured bone was strengthened in a good position.
