2.4 mm Volar Locking Compression Plate for Treatment of Unstable Distal Radius Fractures

Purpose: To evaluate outcomes 2.4 mm volar locking compression plate for treatment of unstable distal radius fractures.\nMaterials and Methods: We retrospectively analyzed the results in 22 cases, which were treated by 2.4 mm volar locking compression\nplate. We evaluated the clinical results according to the Mayo wrist performance scoring system and radiographic results.\nResults: All cases had bony union. The mean Mayo wrist performance score was 85.23. Between preoperative and immediate\npostoperative radiographic measurements, the mean radial length was improved from 6.04 mm to 9.68 mm, radial inclination\nfrom 15.61o to 19.61o, volar tilt from −13.73o to 7.66o and intraarticular step-off from 0.79 mm to 0.33 mm (p＜0.05). Between\nimmediate postoperative and latest follow-up radiographic measurements, the mean loss of radial length measured 0.86 mm,\nradial inclination 0.41o, volar tilt 0.54o and intraarticular step-off 0.02 mm (p＞0.05). Postoperative complication included that\nflexor pollicis longus and 2nd flexor digitorum profundus were ruptured in 1 case.\nConclusion: Treatment of unstable distal radius fractures using a 2.4 mm volar locking compression plate showed satisfactory\noutcomes. It is a good option to obtain stable fixation without significant loss of reduction.\nKey Words: Distal radius, Unstable fracture, 2.4 mm locking compression plate, Volar approach
