Article source：本站原创 Shoulder joint periarthritis, also known as frozen shoulder, fifty shoulder, mostly seen in middle-aged and elderly people. It manifests itself as pain in the shoulder joint (mostly in the front of the shoulder) in the pain treatment center of Xuanwu Hospital of Capital Medical University, Ni Jiachao, and often radiates to the neck, back, upper arm or forearm, and hand, affecting the shoulder joint activities, and inconveniencing daily life actions such as putting on and taking off clothes and combing hair. It is often triggered by trauma, cold, strain, or a certain disease such as prolonged recumbency or shoulder inactivity. Sometimes the attack is acute, but most of the attacks are slow and last for weeks, months or even years. The pain is worse at night and can affect sleep. There is no redness or swelling in the shoulder joint, and there is limited or widespread pressure pain in the joint and its vicinity, and the surrounding muscles are atrophied. There are no abnormal changes in blood tests or X-rays. Although this disease is very common, it is not life-threatening and many patients experience pain and suffering for a period of time and then get better naturally, or even heal, and all symptoms disappear. Therefore, this disease is also known as “frozen shoulder” or “frozen shoulder”, which means that it will recover naturally in time, just like the spring thaw. The cause of the disease has not been studied deeply enough, and because of other factors, the result has not been really clear yet. With the rapid development of medical science and technology, research into the etiology of frozen shoulder has made great strides, and the concept of frozen shoulder, which used to be vague, has become increasingly clear. It is now believed that frozen shoulder includes at least the following diseases: (1) Frozen shoulder in the narrow sense, i.e. adhesive capsulitis. (2) Instability of the shoulder joint. (3) Acromioclavicular impingement. (4) Subacromial bursitis. (5) Calcific supraspinatus tendonitis. (6) Rotator cuff injury. (7) Glenohumeral arthritis (rheumatic, rheumatoid, osteoarthritis, etc.). (8) Intra-articular free body. (9) Vertigo-biceps long head tendonitis, etc. Therefore, it can be said that periarthritis is a big family. If we compare periarthritis in a broad sense to a fruit basket, then the fruit basket contains the above-mentioned “apples”, “pears”, “grapes”, etc. The fruit basket contains the above-mentioned “apples”, “pears”, “grapes” and other specific fruits with different shapes and tastes. Based on this new understanding, patients with shoulder joint pain who are not treated with functional exercises, medication, plasters, physiotherapy, acupuncture, cupping, etc. should not just observe and wait, but should undergo a comprehensive and detailed examination in order to make a clear diagnosis and treat the cause as soon as possible to prevent stiffness of the joint and lifelong disability. For example, the shoulder impingement syndrome, which mostly occurs in middle-aged and elderly people, is caused by local osteophytes, combined with trauma and inflammation, and soft tissue hypertrophy under the shoulder peak, resulting in impingement, which used to be classified as frozen shoulder and had poor results with general treatment. The latest clinical introduction of shoulder arthroscopy, which allows for both examination and minimally invasive surgery, is welcomed by doctors and patients alike. It is important to note that no matter how advanced the examination and treatment techniques are, prevention is more important. Middle-aged and elderly people should live a normal life, pay attention to balanced nutrition, strengthen exercise, and move their joints appropriately. Avoid trauma to the shoulder and pay attention to keeping warm. Avoid direct blowing of electric fans or air conditioners on the shoulder in summer. When sleeping in spring, autumn and winter, the shoulder should not be exposed outside the quilt.
