Truly anatomic coracoclavicular ligament reconstruction with 2 Endobutton devices for acute Rockwood type V acromioclavicular joint dislocations

Background: Truly anatomic coracoclavicular ligament reconstruction (TACCR) according to the original insertions is a creative new method for the treatment of severe acromioclavicular separation. This research analyzed the clinical and radiologic results of TACCR in 25 patients with at least 2-year follow-up. Methods: The study enrolled 25 patients with Rockwood type V acromioclavicular joint dislocations who underwent TACCR using 2 Endobutton (Smith & Nephew Inc., Andover, MA, USA) devices from May 2013 to October 2015. Patients were assessed with clinical and radiologic follow-up at 3, 6, 12, 18, and 24 months postoperatively. The clinical assessments consisted of the visual analog scale and the Constant score. The radiographic evaluations were performed by measurements of the coracoclavicular distance. Results: The mean follow-up was 34 +/- 6.8 months (range, 24-48 months). The visual analog scale and Constant scores revealed significant advancements from 5 +/- 0.9 (range, 4-7) and 45 +/- 5.6 (range, 30-54) scores preoperatively to 0 +/- 0.5 (range, 0-2) and 95 +/- 2.9 (range, 91-98) scores at 24 months postoperatively, respectively. The coracoclavicular distance significantly decreased from 23 +/- 5.4 mm (range, 16-34 mm) preoperatively to 8 +/- 0.9 mm (range, 7-10 mm) at the final follow-up. Conclusions: TACCR represents a safe, reliable and creative surgical technique that yields good to excellent clinical and radiologic outcomes in the treatment of severe acromioclavicular separation.
