Purpose: To evaluate clinical and radiological results of AO type C distal radius fractures treated with a volar locking plating system.
Materials and Methods: We retrospectively reviewed 31 patients with AO type C distal radius fracture treated with a volar locking plating system. We evaluated the clinical results according to the Mayo wrist performance scoring system and disabilities of the arm, shoulder and hand (DASH) score and evaluated the radiographic results.
Results: All cases had bony union. The mean Mayo wrist performance score was 81.9. The mean DASH score was 11.2. Between preoperative and immediate postoperative radiographic measurements, the mean radial length was improved from 8.8 mm to 13mm, radial inclination from 14.7° to 22.5°, volar tilt from -11.3° to 9.4° and intra-articular step-off from 2.2 mm to 0.3 mm (p<0.05). Between immediate postoperative and latest follow-up radiographic measurements, the mean loss of radial length measured under 1 mm, radial inclination under 1°, volar tilt under 1° and intra-articular step-off under 1 mm (p>0.05). Internal fixation using volar locking compression plate could allow early postoperative exercise and could result in low incidence of postoperative complication. All cases showed bone union showing no evidence of malunion, nounion, nor metal failure.
Conclusion: Treatment of AO type C fractures using a volar locking plate showed satisfactory outcomes. It is a good option to obtain stable fixation without significant loss of reduction.
