Treatment of old acromioclavicular dislocation by reconstruction of acromioclavicular and coracoclavicular ligaments / 中华创伤杂志

ABSTRACT

Objective To explore new treatment methods for old acromioclavicular dislocation. Methods Twenty-nine cases of old acromioclavicular dislocation were treated with augmenting reconstruction of acromioclavicular ligament by coracoacromial ligament and augmenting reconstruction of coracoclavicular ligament by conjoining tendon with biceps brachii muscle and coracobrachialis muscle in coracoid. Twenty-five cases were followed up with follow-up period of 3-36 months. There were 10 cases in grade Ⅱ and 15 in grade Ⅲ according to classification of Allman. Results Of 25 cases with follow-up, 16 were excellent and 9 satisfactory according to the Lazzcano standard. There were no other complications or dislocations. Conclusions Reconstruction of acromioclavicular and coracoclavicular ligaments for treatment of old acromioclavicular dislocation is an efficient method with advantage of rigid fixation and accords with micro-motion physiological function of acromioclavicular joint.
