Abstract: Objective To determine the functional outcome of high strength wires hang together with autologous tendon to reconstruct coracoclavicular ligment for elderly patients with acromioclavicular joint dislocations. Methods This study is retrospective study, examined elderly patients with acromioclavicular joint dislocations from June, 2014 to January, 2016. Twenty-five elderly patients of Rockwood Ⅲ-Ⅳ acromiocluv, cular joint dislocation were observed, the mean patient age at the time of surgery was 64.3 years (range, 62 to 71 years). All patients were treated with two high strength wires and autologous tendon to reconstruct coracoclavicular ligment. The shoulder joint range of motion before treatment and post treatment were recorded, we compared VAS scores, UCLA scores, ASES scores to determine the function of shoulder joint. Results All were available for follow-up at a mean of 1.5 years. Overall, functional outcome was improved from baseline compared with final follow-up for VAS scores[(4.3±1.2) points vs. (0.8±0.3) points, P<0.01], ASES scores[(64.1±7.4) points vs. (92.3±3.2) points, P<0.01], and UCLA scores[(22.1±3.9) points vs. (34.8±2.4) points, P<0.01]. The shoulder joint range of motion was improved. Conclusion High strength wires hang together with autologous tendon to reconstruct coracoclavicular ligment for elderly patients with acromioclavicular joint dislocations is a good method which has less damage, it can obtain a favorable clinical effect, and have good functional rehabilitation.
