Rotator Cuff Injury
Rotator cuff syndrome [7], also known as shoulder impingement syndrome [8], occurs when there is an injury to the structures that help stabilize this region.
The rotator cuff is formed by a set of four muscles responsible for moving and providing stability to the shoulder, which are the infraspinatus, the supraspinatus, the teres minor and the subscapularis, together with its tendons and ligaments. Injuries in this region usually occur due to inflammation caused by wear, irritation or an impact due to excessive use of the joint, which is more common in athletes or people who work carrying weight with their arms.
How it feels: It causes symptoms such as shoulder pain, in addition to difficulty or weakness in raising the arm, and can be caused both due to tendonitis and partial or total rupture of tendons in the region
How to treat: To treat this syndrome, rest, ice and physiotherapy are indicated, and the orthopedist may also indicate the use of anti-inflammatory drugs, such as ketoprofen, to relieve pain or, in cases where there is no improvement, it can surgical treatment is necessary.
