To evaluate outcomes 2.4 mm volar locking compression plate for treatment of unstable distal radius fractures.

We retrospectively analyzed the results in 22 cases, which were treated by 2.4 mm volar locking compression plate. We evaluated the clinical results according to the Mayo wrist performance scoring system and radiographic results.

All cases had bony union. The mean Mayo wrist performance score was 85.23. Between preoperative and immediate postoperative radiographic measurements, the mean radial length was improved from 6.04 mm to 9.68 mm, radial inclination from 15.61° to 19.61°, volar tilt from -13.73° to 7.66° and intraarticular step-off from 0.79 mm to 0.33 mm (p<0.05). Between immediate postoperative and latest follow-up radiographic measurements, the mean loss of radial length measured 0.86 mm, radial inclination 0.41°, volar tilt 0.54° and intraarticular step-off 0.02 mm (p>0.05). Postoperative complication included that flexor pollicis longus and 2nd flexor digitorum profundus were ruptured in 1 case.

Treatment of unstable distal radius fractures using a 2.4 mm volar locking compression plate showed satisfactory outcomes. It is a good option to obtain stable fixation without significant loss of reduction.
