Reconstruction of coracoclavicular ligaments with allogeneic tendon graft combined with anchor fixation for acromiodavicular dislocation / 中华创伤骨科杂志

ABSTRACT

Objective To report treatment of acromiodavicular dislocation by reconstruction of coracoclavicular ligaments with allogeneic tendon graft and anchor internal fixation.Methods From January 2013 through January 2016,24 patients with acromiodavicular dislocation were treated at our department.They were 19 men and 5 women,21 to 46 years of age (average,31.4 years).Fourteen left and 10 right sides were involved.By Rockwood classification,6 cases were type Ⅲ,8 type Ⅳ and 10 type Ⅴ.All of them were treated with reconstruction of coracoclavicular ligaments with a11ogeneic tendon graft and anchor internal fixation.Maintenance of the reduced acromioclavicular joint was followed up postoperatively.Disabilities of the Arm,Shoulder and Hand (DASH) scores and Constant-Murley shoulder scores were used to evaluate the shoulder functions before and after operation.Results All the patients were followed up for 6 to 15 months (average,11.4 months).The shoulder joints were well reduced after removal of anchor internal fixation.21 cases were rated as excellent and 3 as good,giving a good to excellent rate of 100％.The fractures healed after 10 to 12 months (average,10.4 months).Compared with the preoperative value (10.7 ± 3.0),the DASH score at final follow-up was significantly improved (6.4 ± 2.6) (P ＜ 0.05);compared with the preoperative value (67.2 ± 2.6),the Constant-Murley score at final follow-up was also significantly improved (92.2 ±4.7) (P ＜ 0.05).The patients' satisfaction was 83.3 ％ (20 / 24).No adverse reaction occurred.Conclusion Reconstruction of coracoclavicular ligaments with allogeneic tendon graft combined with anchor fixation is a reliable technique for acromiodavicular dislocation.
