Also representatives of certain professions who work, raising their hands high, experience very severe pain in the shoulder joint. This is due to the fact that the tendons of the rotational cuff rub against the acromion - this is the process of the scapula.

Osteoarthritis of this type of joint is a chronic progressive disease of the joints of the shoulder. With it, the bone tissue adjacent to the cartilage and the cartilage itself, undergo dystrophic changes.

Some time later, the cartilaginous surfaces of the joint begin to degrade, they become rough, and certain areas are formed on which the salt - osteophytes - is deposited.

Clinical manifestations, as well as pathological changes, develop rather slowly. I must say that the course of the disease is chronic. Sometimes, when you feel better, it can become worse. Pain is the most important symptom of the disease, it increases with exercise, and joint mobility is limited.

In the joints of the waist and the shoulder itself, the ratio of movements during the execution of complex movements of the upper limb is called the humerus rhythm. Violation of it is typical for the disease is the shoulder joint.

Near the joint is the brachial plexus, capable of responding to the pathological process in it. If there are intra-articular osteophytes, with some specific gestures, a painful click may occur, which will entail a restriction of movements in the joint.
