Purpose: The object of this study is to evaluate the clinical and radiographic outcomes of two different kinds of dorsal plating for dorsally displaced distal radius fractures.
Methods: Forty-three patients with dorsal plate fixation for distal radius fracture were retrospectively reviewed. Twenty-four patients were treated with nonlocking dorsal plate (group I) and nineteen patients with locking dorsal plate (group II). Range of motion and Green and O¡¯Brien score were evaluated as clinical results, and radial inclination, radial length, volar tilt at postoperative and last follow up were evaluated as radiographic results.
Results: According to AO classification system, there were 18 type A fractures, 4 type B fractures, 21 type C fractures. In group I, the mean flexion and extension were 65.0¡Æ and 65.3¡Æ, respectively; ulnar and radial deviation were 25.5¡Æ and 20.8¡Æ; pronation and supination were 80.0¡Æ and 80.4¡Æ. In group II, the mean flexion and extension were 64.5¡Æ and 67.3¡Æ, respectively; ulnar and radial deviation were 30.6¡Æ and 20.6¡Æ; pronation and supination were 81.4¡Æ and 78.6¡Æ. The mean Green and O¡¯Brien score was 94.4 in group I and 92.2 in group II, and 41 patients had satisfactory result. There was no statistical significant difference in clinical results between the groups. Results of postoperative and last follow-up radiographic analyses for mean radial inclination were 23.9¡Æ and 24.1¡Æ in group I, respectively, and 24.2¡Æ and 24.9¡Æ in group II; radial length were 9.9 mm and 9.7 mm in group I, and 10.1 mm and 9.2 mm in group II; mean volar tilt were 12.2¡Æ and 13.1¡Æ in group I, and 14.8¡Æ and 13.7¡Æ in group II . There were no statistical significant changes within radiographic parameters. No extensor tendon rupture was reported.
Conclusion: Dorsal plate fixation for dorsally displaced distal radius fracture showed satisfactory clinical and radiographic outcomes with low complication rate, regardless of the type of plate.
