Abstract

<br/><strong><span style="font-size: xx-small;">Background: </span></strong><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">Surgical treatments for acromioclavicular (AC) joint dislocation present with some complications. The </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">present study was designed to evaluate the double-button fixation system in the management of acute acromioclavicular </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">joint dislocation. </span></span><br/><span style="font-size: xx-small;"><br/><strong>Methods: </strong></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">This cross sectional study, done between February 2011 to June 2014, consisted of 28 patients who underwent </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">surgical management by the double-button fixation system for acute AC joint dislocation. Age, sex, injury mechanism, </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">dominant hand, side with injury, length of follow up, time before surgery, shoulder and hand (DASH), constant and visual analogue scale (VAS) scores, and all complications of the cases during the follow up were recorded. </span></span><br/><span style="font-size: xx-small;"><br/><strong>Results: </strong></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">The mean age of patients was 33.23±6.7 years. Twenty four patients (85.71%) were male and four (14.28%) </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">were female. The significant differences were observed between pre-operation VAS, constant shoulder scores and post-</span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">operation measurements (</span></span><em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">P</span></span></em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">=0.001, </span></span><em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">P</span></span></em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">=0.0001, </span></span><em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">P</span></span></em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">=0.0001, respectively). There were not any significant differences between </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">right and left coracoclavicular (</span></span><em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">P</span></span></em><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">=0.238), but two cases of heterotrophic ossifications were recorded. The mean follow-up </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">time was 16.17±4.38 months. </span></span><br/><span style="font-size: xx-small;"><br/><strong>Conclusion: </strong></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">According to the results, the double-button fixation system for management of acute acromioclavicular joint </span></span><span style="font-family: Arial,Arial; font-size: xx-small;"><span style="font-family: Arial,Arial; font-size: xx-small;">dislocation has suitable results and minimal damage to the soft tissues surrounding the coracoclavicular ligaments. </span></span>
