The effect of endobutton in the treatment of acromioclavicular joint dislocation

Objective: To investigate the effects of endobutton in the treatment of acromioclavicular joint dislocation.Methods: Thirty-one patients with Rockwood Ⅲ,Ⅳ and Ⅴ type cromioclavicular joint dislocation were treated with the modified button plate internal fixation.The shoulder joint function was evaluated according to Constant-Murley score.Results: All patients were followed up for 5 to 26 months.The average Constant scores before operation,at 1 week,and 1,3 and 6 month after operation were(30.2±6.3),(86.3±6.3),(93.2±3.5),(95.2±3.1) and(95.4±3.7),respectively.The difference of Constant-Murley score between before and after operation was statistically significant(P<0.01).Conclusions: The effect of endobutton in the treatment of acromioclavicular joint dislocation is good,which is an ideal treatment for acromioclavicular joint dislocation.
