title: Percutaneous double-button fixation method for treatment of acute type III acromioclavicular joint dislocation.
abstract: OBJECTIVE
  The aim of this study was to evaluate the functional and radiological results of patients treated with the percutaneous double-button technique for acute acromioclavicular (AC) joint dislocation.
  
  
  METHODS
  A retrospective evaluation was performed of 13 patients surgically treated for acute Type III AC joint dislocation with the percutaneous double-button fixation method. The coracoclavicular (CC) distance of the affected side was compared with that of the healthy side on anterior-posterior radiographs obtained at the final follow-up. In the functional evaluation, Disabilities of the Arm, Shoulder and Hand (DASH), Constant, and visual analog scale (VAS) scores were used.
  
  
  RESULTS
  The 13 patients in the study included 12 males and 1 female with a mean age of 43.4 years (range: 22-60 years). The mean follow-up period was 13.61 months (range: 9-24 months). The mean CC distance on the operated side was 9.23 mm (range: 8-15 mm), and when compared with the healthy side, no statistically significant difference was observed. Preoperative Constant scores of a mean of 30.3 (range: 18-42) increased to 84.4 (range: 70-90) at the final follow-up. Preoperative DASH scores had a mean of 14.1 (range: 11-28) and decreased to 0.4 (range: 0-3) at the final follow-up (p<0.001). Mean preoperative VAS score was 6.0 (range: 5-8), which decreased to 0.6 (range: 0-3) at the final follow-up (p<0.001).
  
  
  CONCLUSIONS
  The percutaneous double-button fixation technique is a safe, practical, and effective fixation method that can be used as an alternative to arthroscopic and open methods for acute Type III AC joint dislocations.
