displaced intra-articular fractures of the distal radius: open reduction with internal fixation versus bridging external fixation

background distal radius fracture is common in all ages. mobility and wrist function is important. the choice of treatment should aim for optimal function with minimal complications. objectives in this study we compared two surgical approaches, open reduction and internal fixation (orif) and closed reduction with external fixation (cr + ef), for treatment of intra-articular distal radius fractures. patients and methods ninety-four patients with distal radius fracture (type 3, 4 and 5 fernandez classification) were treated with two surgical methods (orif and cr + ef); 55 were treated with cr + ef and 39 were treated with orif by different surgeons. all patients were assessed at the end of the first, third and sixth week; and then after the third, sixth and 12th month. at the end of the follow-up, all patients completed the michigan hand outcome questionnaire (mhoq). we compared radiological parameters of distal radius, range of motion (rom) of the wrist, duration of rehabilitation, complication and patient satisfaction of the methods. results in our study, radiological findings for the orif group were radial inclination (ri): 19.35, radial length (rl): 10.35, radial tilt (rt): 8.92, and ulnar variance (uv): 1.64, while for the cr + ef group these were ri: 15.13, rl: 8, rt: 4.78, and uv: 0.27. the rom for orif were flexion/extension (f/e): 137, radial/ulnar deviation (r/u): 52, and supination/pronation (s/p): 141, while for the cr + ef group these were f/e: 117, r/u: 40 and s/p: 116. michigan hand outcome score for orif was 75% and for ext. fix was 60%. the rate of complication with the orif method was 58% and in ext. fix this was 69%. the patients in cr + ef had more than the orif course of physiotherapy and rehabilitation. conclusions in comparison of orif and cr + ef, all results including functional score, clinical and radiologic criteria were in favor of the orif method while there were less complications with this method. we believe that orif is a better method for treatment of these types of fractures.
