Abstract:
Isolated dorsal dislocation of the trapezoid is an unusual injury. In 1990 Ostroski found only 15 cases of dorsal dislocation of the trapezoid in the world literature. The trapezoid is a wedge-shaped bone with the larger dorsal and smaller volar surface area, and stabilized by strong palmar ligaments. Therefore the dislocation of the trapezoid is produced hy a violent force against the dorsum of the hand on a rigid object and often associated with other injuries of the hand. The diagnosis is often missed or delayed perhaps secondary to the difficulty in interpreting the X-ray if you have not kept in mind. Several therapeutic modalities are performed from the collected experience of the authors reporting this injury. A rare example of an isolated dorsal dislocation of the trapezoid bone is described.
