摘要
dorsal plate for the distal radius was designed to provide rigid fixation and thus allow early motion. It functions as a blade plate, lessening the role of metaphyseal screws, and providing internal neutralization rather than compression. The rigidity and strength of the plate were compared to the existing T-plate in an unstable, extra-articular fracture model in paired, fresh-cadaver, axially loaded radii. The dorsal plate construct was significantly stronger and more rigid than the T-plate construct. The failure mode was similar for both plate types; 8 of 10 constructs failed with plate bending and screw loosening, while the oldest specimen pair showed primary bone failure. Compared to the T-plate, the dorsal plate transmitted a greater single axial load from the articular surface to the shaft.
