Isolated Carpal Dislocation Of The Trapezium

Abstract

Trapezium fractures and dislocations of the trapezium are both extremely rare injuries whether they occured with or without fractures of the surrounding bones. Specific radiological images can be difficult to help for the diagnosis. CT scan may be necessary for the diagnosis and adequate treatment. We are presenting an unusual case of volar and radial isolated trapezium dislocation concomitant second metacarpal basis fracture in which is treated by using open reduction and Kirschner wire fixation. In our case, isolated dislocation of trapezium was a result of violent and direct trauma. Different techniques have been proposed to achieve a stable fixation and the treatment outcomes. In our case, open reduction, Kirschner wire fixation and intercarpal ligament repair through dorsal approach are recommended for satisfactory outcomes in similiar cases.
