Abstract:Objective To introduce and evaluate a method for reconstruction of coracoclavicular and acromioclavieular ligaments using allogeneic tendon graft united with hook plate in the management acromioclavicular joint dislocation. Methods Between March 2011 and June 2014, 14 cases of acromioclavicular joint dislocation were treated with allogeneic tendon graft united with hook plate to reconstruct the coracoclavicular and acromioclavicular ligaments, which included 3 cases of Rockwood type Ⅲ, 5 cases of type Ⅳ and 6 cases of type Ⅴ. After the removal of the hook plates in 6-12 months postoperatively, maintenance of the reduced acromioclavicular joint, patients' satisfaction, DASH and Constant-Murley shoulder scores were documented during follow-up evaluation. Results All the patients were followed up for 10-18 months (mean 13 months). After the removal of the hook plates, none of the reduced acromioclavicular joints had redislocation on X-ray evaluation. The overall satisfaction rate was 81.3%. There was no significant difference in the mean Constant-Murley score [preoperative (91.6 ± 3.8) vs postoperative (93.5 ± 4.2)] or mean DASH score [preoperative (6.6 ± 2.9) vs postoperative (6.9 ± 2.4)] before and after the removal of the hook plates (P > 0.05). Conclusions Allogeneic tendon graft united with hook plate is a reliable technique for reconstruction of coracoclavicular and acromioclavicular ligaments for the treatment of Rockwood type Ⅲ-Ⅴ acromiodavicular dislocation. It can maintain good reduction of acromioclavicular joint, ensure the reconstructive effect of the ligaments and restore the stability and function of acromioclavicular joint.
