Current evidence fails to show differences in effectiveness between conservative and surgical treatment of subacromial impingement syndrome.

摘要

Dorrestijn and colleagues identified four studies of low to medium quality, characterized by a high degree of variation in outcomes, treatments, and potential selection bias, to compare the outcomes of operative and nonoperative treatment for subacromial impingement syndrome. All studies showed improvement in outcomes regardless of the approach used (operative compared with nonoperative), and the authors state that no confident conclusions can be made as to which treatment is better.
