Objective To explore the method and evaluate the effect of locking compression plate (LCP)fixation of intraarticular unstable distal radial fractures.Methods Thirty patients with intraarficular unstable distal radial fractures were treated with LCP.According to AO/ASIF classification,there were 6 cases of type B2 fractures,7 cases of type B3,7 cases of type C1,8 cases of type C2,2 cases of type C3.Results After 6 to 24 months(average 12 months)following up,there were 15 cases graded as excellent,10 eases as good,3 cases as fair,and 2 cases as poor,according to X ray and wrist function assessment.The overall satisfaction rate was 83.3％.Conclusion Volar LCP fixation is a safe and effective treatment for intraarticular unstable distal radial fractures.It could effectively prevent loss of reduction,avoid tendon irritation and other complications if selecting implant angle for locking screw according to the specific intraoperative circumstances.
