Subacromial impingement syndrome is a common cause of
shoulder pain. The purpose of this article is to review the clinical
presentation, physical examination findings, and differential diagnosis
of impingement syndrome. Using an evidence-based approach, we propose
an algorithm for the management of subacromial impingement syndrome
including indications for nonoperative management, advanced imaging,
and operative management.
