Long time lifting and pulling heavy objects - the Shoulder joint that has been strained may be "frozen"! Lack of emphasis on functional exercise after shoulder injury - long-term lack of activity can lead to "frozen shoulders"! Grasping the horizontal bar and swinging the rings - unscientific exercise methods can actually make "frozen shoulders" come to you! Don't pay attention to keeping warm in the air-conditioned room - be careful that Shoulder joint will be "frozen"! In addition to the "frozen shoulder" with limited activity, there is another characteristic of "frozen shoulder", namely, periarthritis of shoulder, also known as periarthritis of Shoulder joint joint, commonly known as "fifty shoulders". Periarthritis of shoulder is a common disease characterized by pain of Shoulder joint and inconvenient movement. The disease tends to occur at about 50 years old. It is the most common disease of Shoulder joint in middle-aged and elderly people. The incidence rate of women is slightly higher than that of men, and it is mostly seen in manual workers. Without effective treatment, the functional activities of Shoulder joint may be seriously affected. The patient's Shoulder joint may have extensive tenderness and radiate to the neck and elbow, and muscle atrophy may occur to varying degrees. Our Shoulder joint is composed of the glenoid of the Scapula and the humeral head. The Shoulder joint is filled with joint fluid for lubrication, and its periphery wraps around the Joint capsule for fixation and protection of the joint. Inflammation is the main reason for the adhesion of Shoulder joint surface tissue and the reduction of joint fluid. There are many causes of inflammation, such as trauma, surgery, long-term inactivity of Shoulder joint, etc. In addition, "frozen shoulder" may also be one of the manifestations of systemic diseases, such as diabetes, rheumatism, etc. To judge whether Shoulder joint pain is "frozen shoulder" or not, doctors mainly diagnose it according to physical examination, with decreased range of motion and typical tenderness points around the Shoulder joint, which can basically be diagnosed. In order to clarify the degree of disease development, it is also necessary to improve imaging examinations such as X-ray and magnetic resonance imaging, and if necessary, to conduct blood tests to exclude other systemic diseases. Most "frozen shoulder" Conservative management can "unfreeze" the Shoulder joint. The magnetic resonance or ultrasonic examination is a safe and effective inspection method, which can not only help us judge the specific location and degree of Shoulder joint injury, but also guide us to take more reasonable treatment measures. In fact, most "frozen shoulders" can be successfully "thawed" by Conservative management as long as they are found in time and paid enough attention. The overall principle is to reduce pain and maintain joint range of motion as much as possible. For example, oral NSAIDs, hot or cold compress on Shoulder joint, massage and other means can effectively eliminate inflammation of Shoulder joint and relieve pain. Reasonable functional exercise is an important means to maintain the range of motion of Shoulder joint joint. On the premise of not aggravating the injury, Shoulder joint should be moved as far as possible to accelerate the functional recovery of Shoulder joint. Remember to adopt a weightless active exercise method to be safe enough. If the Shoulder joint's range of motion is severely limited, or the pain is beyond control, which seriously affects the quality of life, further treatment measures should be taken. If the examination shows that there is no ligament tear, the injection treatment of Shoulder joint can usually be selected to quickly relieve the pain and improve the range of motion of the joint. Because "frozen shoulder" is caused by inflammation, if chronic inflammation can be eliminated, then the related symptoms of Shoulder joint can be quickly relieved. Injection therapy is a widely recognized approach to
