Purpose: The purpose of this study was to evaluate the radiological and clinical results of plate fixation and external fixation with additional devices for treating distal radius fracture in AO type C subtypes, and propose a treatment method according to the subtypes.
Materials and Methods: Two hundred and one AO type C distal radius fracture patients were retrospectively reviewed. Eighty-five patients in group 1 were treated with volar or dorsal plate, and 116 patients in group 2, were treated with external fixation with additional fixation devices. Clinical (range of mtion, Green and O'Brien's score) and radiological outcomes were evaluated.
Results: At the 12-month follow-up, group 1 showed flexion of 64.4°, extension of 68.3°, ulnar deviation of 30.6°, radial deviation of 20.8°, supination of 76.1°, and pronation of 79.4° in average; group 2 showed flexion of 60.5°, extension of 66.9°, ulnar deviation of 25.5°, radial deviation of 18.6°, supination of 73.5°, and pronation of 75.0° in average. The mean Green and O'Brien score was 92.2 in group 1 and 88.6 in group 2. The radial height of group 1 and group 2 was 11.6/11.4 mm; radial inclination was 23.2°/22.5°; volar tilt was 11.6°/8.7°; and the ulnar displacement was 1.27/0.93 mm.
Conclusion: Judicious surgical techniques during device application and tips for postoperative management during external fixation can produce similar clinical results compared with internal fixation patients.
