MICROANATOMY

Detailed explanation-1: -One of the easiest methods to determine a torn rotator cuff is certainly the Drop Arm Test. This can be especially useful to assess for full thickness rotator cuff tears of the supraspinatus and infraspinatus, and also to diagnose sub-acromial pain syndrome which is shoulder impingement.

Detailed explanation-2: -Neer sign: With the scapula fixed into a depressed position, this test is performed by the examiner maximally forward flexing the patient’s arm (passive range of motion testing). Localized pain on the anterior shoulder suggests subacromial impingement, whereas posterior shoulder pain suggests internal impingement.
