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.

Trapezoid fracture is a rare condition and especially, isolated trapezoid fracture is most rare condition of carpal bone fracture. And principle of treatment has not yet been established. Most of trapezoid fractures can be treated using cast but displaced fracture or fracture combined with other carpal bone fractures may require operative treatment. There have been reports about case of conservative treatment in trapezoid stress fracture but no report about case of operative management. We treated a trapezoid stress fracture in a weight lifting athlete by operative treatment and report the results with literature review.
