RESUMO
OBJECTIVE@#To explore the clinical effect of the modified double Endobutton technique combined with Nice node in the treatment of Rockwood Ⅲ-Ⅴ acromioclavicular joint dislocation.@*METHODS@#From March 2016 to January 2019, 23 patients with Rockwood Ⅲ-Ⅴ acromioclavicular joint dislocation were treated with modified double Endobutton technique to reconstruct coracoclavicular ligament and Nice node to repair acromioclavicular ligament, including 18 males and 5 females, aged 31 to 53 (43.2±5.4) years, 9 on the left and 14 on the right, and the time from injury to operation was 1 to 10 days. Before operation, X-ray films and CT three-dimensional reconstruction of bilateral shoulder joint were performed. Postoperative complications were observed. Six months after operation, DASHand Constant-Murley scores were used to evaluate the treatment effect.@*RESULTS@#The incision healed in one stage after operation, and no complications such as vascular and nerve injury and stress fracture occurred. All patients were followed up for 6 to 24 (12.0±4.9) months. At 6 months follow-up, the DASH score was 0.40±0.10 lower than that of 19.80±4.50 before operation, and the Constant-Murley score was 94.20±4.20 higher than that of 38.60±3.90 before operation.@*CONCLUSION@#The treatment of Rockwood Ⅲ-Ⅴ dislocation of acromioclavicular joint with double Endobutton technique and nice knot is satisfactory in the early stage. The long-term effect and complications need further follow-up.
