Isolated trapezoid fractures: a case report with compilation of the literature.

Isolated fractures of the trapezoid bone have been rarely reported in the literature, the mechanism of injury being an axial or bending load transmitted through the second metacarpal. We report a case of an isolated, nondisplaced trapezoid fracture that was sustained by direct trauma and subsequently treated successfully in a short-arm cast. Diagnostic and treatment strategies for isolated fractures of the trapezoid bone are reviewed as well as the results of operative and nonoperative treatment.
