Treatment of double loop double button plate fixation on patients with complete acromioclavicular joint dislocation

Abstract

Objective To investigate the application of the double loop double button plate fixation on treatment of patients with complete acromioclavicular joint dislocation.Methods Twenty-six cases with Rockwood type Ⅲ complete acromioclavicular joint dislocation were selected as our subjects who hospitalized from Jan.2011 to Jul.2013 and underwent using dual loop button plate technology of double fixation and reconstruction of coracoclavicular ligament fixation.There were 19 males and 7 females.Their age ranged from 18 to 62 years old and average was 30.2 years old.Adopt Lazzcano standard score was used to evaluate the shoulder joint function.Results X-ray examination showed the acromioclavicular joint of all patients were fixed in right place.Shoulder function was back to normal after 1 to 2 months and no pain or mild pain were showed in some patients.Twenty-four cases were followed up for 6-24 months,and the average followed up periods was 18.2 months.According to Lazzcano standard score to assess the function of shoulder join.Twenty cases were excellent and 4 cases were in good.The excellent and good rate was 100％.Conclusion Dual loop button plate technique is proved to be a good approach in the treatment of complete acromioclavicular joint dislocation with small trauma,stable fixation.Meanwhile patients can perform early functional exercise and no recurrent dislocation without the need of internal re-fixation.
