Résumé
Objective To compare recent curative effect between double Endobutton technique and clavicular hook plate (CHP) in patients with Tossy grade Ⅲ acromioclavicular separation.Methods One hundred and forty-nine patients with Tossy grade Ⅲ acromioclavicular dislocation were divided into control group (78 cases,treated with CHP) and observation group (71 cases,treated with double Endobutton technique) according to treatment method.The postoperative injured shoulder visual analogue score (VAS),abduction-rise activity and flexion-rise activity,Constant-Murley score and Karlsson grade were compared between 2 groups.Results All the patients successfully completed the operation,and the postoperative follow-up time was 9-40 (15.8 ± 5.2) months.The injured shoulder abduction-rise activity and flexion-rise activity postoperative 9 months in observation group were (100.9 ± 13.3)° and (131.6 ± 13.4)°,in control group were (81.4 ± 8.4)° and (96.7 ± 10.9)°; the injured shoulder VAS in observation group and control group were (2.2-± 0.8) and (3.0 ± 0.9) scores,and there were statistical differences between 2 groups (P ＜ 0.01).The Constant-Murley score in observation group and control group were (85.4 ± 6.4) and (82.5 ± 6.2) scores,the excellent and good rate of Karlsson grade in observation group and control group were 84.5％(60/71),91.0％ (71/78),and there were no statistical differences (P ＞ 0.05).Conclusions The recent curative effect of double Endobutton technique and CHP in patients with Tossy grade Ⅲ acromioclavicular separation is similar.
