Charlie Chaplin in Shoulder Arms (1918)

Shoulder impingement occurs when the top outer edge of your shoulder blade, called the acromion, rubs against (“impinges on”) or pinches your rotator cuff beneath it, causing pain and irritation. Surgery is considered if nonsurgical treatments don’t relieve your pain. One surgery called a subacromial decompression or arthroscopic shoulder decompression removes part of the acromion to create more space for the rotator cuff. #shoulderimpingement #shoulderinjury #shoulderinstability #shouldermobili
