However, they only have a vague understanding of its causes. It is difficult to pinpoint exact reasons for the development of periarthritis of the shoulder. But once symptoms appear, it is necessary to seek medical attention promptly. The condition usually arises from long-term injuries, and stroke can also be one of the causes of periarthritis. Any condition that restricts the movement of the shoulder joint could potentially be a cause of periarthritis.
Since there are various reasons for the formation of periarthritis, we can classify these causes into primary and secondary ones based on their symptoms.
The shoulder joint has the largest range of motion among all joints in the human body. Its joint capsule is relatively loose, and the stability of the joint mainly relies on the strength of muscles, tendons, and ligaments around the joint to maintain. Due to the poor blood supply of the tendons themselves, as well as the degenerative changes that occur with age, plus the frequent activity of the shoulder joint in daily life which often subjects surrounding soft tissues to friction and compression, chronic fatigue damage easily occurs, gradually promoting the formation of primary periarthritis of the shoulder.
Secondary periarthritis forms as a result of other diseases leading to periarthritis around the shoulder joint. The most common type is periarthritis that follows acute trauma to the shoulder or upper limb. Shoulder traumas include fractures such as clavicle fractures, scapula fractures, proximal humerus fractures, etc., as well as rotator cuff tears and ligament ruptures, all of which require the shoulder joint to be immobilized for a longer period. Upper limb traumas, especially humeral fractures, also necessitate prolonged immobilization of the shoulder joint. Long-term fixation of the shoulder joint can lead to adhesion and contracture of the shoulder joint capsule, resulting in periarthritis. Additionally, cervical spondylosis and lower back diseases can affect shoulder joint movement, thus causing secondary periarthritis.
This is the classification of the causes of periarthritis of the shoulder, hoping to provide people who are less familiar with the causes of periarthritis with a basic understanding of its formation.
