The analysis on the therapeutical effectiveness of coraco-clavicular screw and tension-band wire fixation in acromioclavicular dislocation

Objective To research the different results of old and middle-young patients after the operation of coraco-clavicular screw and tension-hand wire fixation in Tossy Grade Ⅲ acromioclavicular dislocation. Methods In this study, there were forty three patients with acromioclavicular dislocation, Tossy grade Ⅲ. All patients were adopted the therapies of coraco-clavicular screw and tension-band wire fixation in the acromioclavicular dislocation. There were twenty-eight men and fifteen women with an average age of 42 years. They were divided into two groups:the middle and young age(less than sixty) ,24 cases;and senile group(over sixty) , 19 cases. The results were compared with the statistical result of Phillips and Bragin. All the patients had been followed up on an average of 2.7 years. Results In the aspect of pain and myodemia, there was no significant difference between the results of young and middle group and that of Phillips;in the developmental rate of deformity, the pain:96% of the younger and 95% of the old were no or little pain. The range of movement: 92% of the younger and 69% of the old were normal or near normal. The power:96% of the young and 84% of the old were normal or near normal. The complications:Residual deformity of loss of reduction was present in 10% of the old and there is no deformity of loss of reduction was present in the young group. There were 4% unsatisfactory in younger and 26% unsatisfactory in the old. The movement and satisfaction of the old were worse,compared with that of Phillips' in younger(P0.05). The young's incidence of deformity was lower,compared with the result of Bragin(P0.05). Conclusion This kind of surgical operation is suitable for younger patients,but not suitable for the old patients with the same disease.
