Impingement of the shoulder was previously thought to be precipitated by shoulder abduction and surgical intervention focused on lateral or total acromionectomy. [4] [25] In 1972, Charles Neer proposed that impingement was due to the anterior third of the acromion and the coracoacromial ligament and suggested surgery should be focused on these ...
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

Examiner will passively abduct the patient's shoulder (humerus) to 90 degrees. The patient is then asked to slowly lower or adduct the shoulder to their side. If the patient is unable to perform this motion, the examiner can hold the humerus at 90 degrees of abduction and apply slight pressure to the distal forearm.
Adhesive capsulitis (AC), also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. [1] It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. [3] There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple ...
The Hawkins-Kennedy test [11] [12] has a sensitivity of approximately 80% to 90% for detecting impingement. The infraspinatus and supraspinatus [13] tests have a specificity of 80% to 90%. [10] A common cause of shoulder pain in rotator cuff impingement syndrome is tendinosis, which is an age-related and most often self-limiting condition. [14]
Localized pain on the anterior shoulder suggests subacromial impingement, whereas posterior shoulder pain suggests internal impingement. [45] For the diagnosis of full-thickness rotator cuff tear, the best combination appears to include once more the painful arc and weakness in external rotation, and in addition, the drop arm sign .
