Salvage of distal radius nonunion with a dorsal spanning distraction plate.

Treatment of nonunion after previous instrumentation of distal radius fractures represents a reconstructive challenge. Resultant osteopenia provides a poor substrate for fixation, often necessitating wrist fusion for salvage. A spanning dorsal distraction plate (bridge plate) can be a useful adjunct to neutralize forces across the wrist, alone or in combination with nonspanning plates to achieve union, salvage wrist function, and avoid wrist arthrodesis in distal radius nonunion.
