Clinical study on the treatment of the Tossy III acromioclavicular Joint dislocation with clavicular hook plate

ObJective To compare and analyze the efficacy of clavicular hook plate (CHP), Kirschner wire (K-wire) and compression screw fixation for the treatment of tossy Ⅲ acromioclavicular Joint dislocation. Methods 54 cases of tossy Ⅲ acromioclavicular Joint dislocation underwent surgery of different fixation including CHP in 18 cases, K-wire in 19 cases and compression screw in 18 cases. The outcome was analyzed retrospectively based on Karlsson’s standard. Results After 12～18 months follow-up, the excellent rate of shoulder function was 94.44% in CHP group, better than 47.37% in K-wire group and 58.82% in compression screw goup(P0.05). Conclusion CHP fixation is better than K-wire and compression screw fixation in treatment of tossy Ⅲ acromioclavicular Joint dislocation.
