Generally
What do we call shoulder tendonitis?
Shoulder tendonitis is a condition caused by the inflammation of the tendons and is one of the most common causes of shoulder pain.
The tendons play a dominant role in the movement of the upper limb, since thanks to them the muscles are attached to the bones and thus the hand acquires the ability to move freely.
Shoulder tendonitis is characterized by acute pain as a primary symptom and significantly restricts shoulder movement.
How is tendonitis created?
The most important tendons in the shoulder are 4, the subscapularis, the supraspinatus, the infraspinatus and the teres minor. All of these form a group of tendons, called the rotator cuff. Another tendon that is vulnerable to stress is the biceps tendon.
These tendons are responsible for all the movements of the shoulder and when their strain exceeds a certain level, inflammation is created. Some of the factors that contribute to its appearance are:
- Intense muscle activity: When the muscles are constantly working to perform a movement, so does the corresponding tendon. So the chances of tendon inflammation are higher.
- Prolonged strain: The continuous strain on the shoulder muscles is related with the increasing accumulation of load on the rotator cuff of the shoulder, resulting in the development of tendonitis.
- Shoulder anatomy: If one of the two bony structures (the acromion), around which the shoulder tendons move, protrudes a lot, then it is easier to develop tendonitis due to the friction of the tendon on the lower surface of the acromion.
