Study of clinical outcome of acromioclavicular joint injury type III-VI treated by EndoButton and threads in adults

Background Acromioclavicular joint dislocations are common in physically active young adults that too most common in persons who are participating in sports activities. Incidence is more in males who are participating in contact sports like rugby, basketball, hockey. It accounts for 9% of all shoulder injuries. Literature says the incidence is 3-4/1,00,000 population. The aim of the present study was to study the functional outcome of acromioclavicular joint after reconstruction of both acromioclavicular and coracoclavicular ligament using endo button system and to provide pain-free, mobile shoulder.

Methods In the present study, 15 patients were selected of age group 20-60 years. Acromioclavicular joint injuries are classified according to Rockwood classification and the findings from the physical examination and anteroposterior and axillary radiographs. All patients were treated as per status of injury level by either conservatively or operatively with open reduction and reconstruction of both ligament by using endo button thread system and its outcomes were assessed clinically and radiologically.

Results Patients were evaluated using American shoulder and elbow score (ASES) score and Constant shoulder score. Average ASES score was 90 (range 68.3-98.3) and constant score was 88 (range 63-96). According to constant score 7 patients had excellent outcome, 6 patients had good outcome, 2 patients had adequate outcome. All patients reported satisfaction with the treatment. The patients were followed upto 6 months.

Conclusions The technique proved to be effective in treating acute. Acromioclavicular joint dislocations (Rockwood type III-VI) with a high degree of patient satisfaction.
