Locked volar plating for unstable distal radial fractures: clinical and radiological outcomes.

We studied 40 patients treated with locked volar plates for unstable distal radial fractures. Outcome was assessed at a mean of 59 weeks, both radiologically and functionally using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire, range of motion and grip strength. The complication rate in our series was 48%. In 11 cases, screw penetration into the radiocarpal joint occurred as a consequence of postoperative collapse. Of these, 25% had malunited and 12.5% ruptured their extensor pollicus longus (EPL) tendon. Functionally, when compared with the contralateral side, 74% of extension, 67% of flexion, 91% of pronation and supination and 81% of grip strength were regained. The mean DASH score was 23. Although locked volar plates can achieve good results in the management of unstable distal radial fractures, there remains a high major complication rate. They should be used with caution particularly in fractures with significant metaphyseal comminution.
