Subacromial bursa

Underneath the acromion is a bursa, which will get inflamed with shoulder impingement and often becomes the cause of a chronic irritation and decreased range of motion and loss of strength. For shoulder decompression to take care of the shoulder impingement, this abnormally swollen and inflamed bursa has to also be taken out and technically this often means that an open surgical decompression procedure needs to be done.
