The Role of Critical Shoulder Angle in Predicting the Outcome of Conservative Management of Shoulder Impingement Syndrome.

Introduction: A rounded shoulder with anterior tilting of the scapula is the common reason for shoulder impingement syndrome. The mainstay of treatment will be shoulder rehabilitation. While the anterior tilting of the scapula is a part of posture, the critical shoulder angle (CSA) is another anatomical factor that may influence the outcome of patients with shoulder impingement syndrome.
