Acromioclavicular joint dislocation: How to achieve anatomical reduction, sustained stability and micro-motion / 中国组织工程研究

ABSTRACT

BACKGROUND: There are many ways to treat acromioclavicular joint dislocation, but there is no uniform standard. The therapeutic efficacy is affected by the damage mechanism, the type of dislocation, the choice of treatment mode and postoperative exercise. OBJECTIVE: To summarize the research progress in acromioclavicular joint dislocation. METHODS: The first author searched literature from PubMed (2010-2019) and WanFang (2010-2019) databases. The key words were “acromioclavicular; dislocation; diagnosis; therapy; anatomical reconstruction; endobutton; internal fixators” in English and Chinese, respectively. After repeated studies were excluded, totally 2 187 articles were retrieved, and 55 eligible articles were included for result analysis. RESULTS AND CONCLUSION: At present, Rockwood types I and II are usually treated nonoperatlvely, while Injures of Rockwood types IV-VI are treated surgically. The treatment of Rockwood type III Is still controversial. In order to maximize the shoulder function, It Is recommended to take active surgery for young and functionally demanding patients. Non-surglcal treatment Is mainly based on strap fixation. Surgical treatment Is Increasingly oriented to minimally Invasive anatomical reconstruction of the coracoclavlcular ligament, for example, Endobutton technique assisted by arthroscopy. Although good short-term results can be obtained, long-term follow-up studies with large samples are still needed to confirm its value in clinical application. Further investigations on the treatment of acromioclavicular joint dislocation are warranted. It has been sought for a surgical method that can achieve anatomical reduction and durable stability and ensure micro-motion of the acromioclavicular joint.
