In our country, the people have? Shoulder pain and activity restrictions on the self-thinking suffering from “frozen shoulder”, and even part of the orthopedic surgeon often use “frozen shoulder” generalized diagnosis of shoulder pain. In fact, shoulder pain is not equal to frozen shoulder at all. Typical misdiagnosis case: Mr. Yuan, 59 years old, complained of pain and weakness in the shoulder joint when moving to a certain angle, and he could not lift his arm up and woke up at night because of the pain and could not lie on his side, and the pain had lasted for more than half a year, and had worsened in February recently, and it was difficult for him to dress and take a bath. She had been to many hospitals, and was treated as “frozen shoulder”, and had taken western medicine, traditional Chinese medicine, physiotherapy, massage, acupuncture, etc. She also followed the doctor’s instructions to exercise, climb the wall, and hang the rings, etc. Although she had been treated with various kinds of conservative treatments, she still didn’t see any improvement, and the situation worsened every time she exercised, and the situation continued to be bad. After careful examination by our shoulder joint specialist outpatient doctor, he got “rotator cuff injury” disease, and the situation has been more serious, and then gave him minimally invasive shoulder arthroscopy surgery, the efficacy of the treatment is very good, has returned to normal. There are a lot of patients like Mr. Yuan in the outpatient clinic with rotator cuff injury mistaken as frozen shoulder, which leads to misdiagnosis and mistreatment, delaying the condition, and in some cases, causing serious consequences. “Frozen shoulder” is an old diagnosis from 140 years ago. With the development of shoulder surgery, especially the clinical application of magnetic resonance and CT, doctors have realized that there are many diseases that cause pain in the shoulder joint, including rotator cuff injury, acromion impingement, rostral impingement, adhesive capsulitis, SLAP, shoulder instability, shoulder pain, frozen shoulder, and so on. injury, shoulder instability, tendinopathy, calcific supraspinatus tendonitis, acromioclavicular arthropathy, shoulder osteoarthritis, thoracic outlet syndrome, and so on. Frozen shoulder” is internationally named as “adhesive capsulitis” because it occurs in middle-aged and old people around 50 years old, which is commonly known as “fifty shoulders” in China. The incidence rate is about 2%~5%, and it is more common in women than in men. Some studies have found that among the elderly people over 60 years of age who consult a doctor for shoulder pain, the incidence of rotator cuff injury and acromioclavicular impingement is the highest, reaching 85%, and its incidence is much higher than that of the so-called “frozen shoulder” (frozen shoulder). Because the differential diagnosis of shoulder pain is inherently difficult, doctors without specialized training in shoulder surgery lack diagnostic certainty. The diagnosis of “frozen shoulder” has been abused for many years, and is like a “garbage can”, where all the shoulder pain that cannot be understood is thrown into the garbage can of “frozen shoulder”. This has led to a lot of under-diagnosis, misdiagnosis and mistreatment. For example, some functional exercises for “impingement of the shoulder” and “frozen shoulder” are opposite to each other, and if you follow the exercises for frozen shoulder like “pulling the sling, climbing up high, and flinging the arm”, it may result in “frozen shoulder”, which may be the cause of “frozen shoulder”, or “frozen shoulder”. If you follow the exercise of “pulling the sling, climbing high, throwing the arm” as in frozen shoulder, it may cause the serious consequence of rotator cuff tearing. The minimally invasive shoulder arthroscopy technology of Ningbo Li Huili Hospital is developing very fast. For the treatment of shoulder joint diseases, shoulder arthroscopy is incomparable with any other therapies and traditional incision surgeries, which can relieve the pain of shoulder joints, repair the torn rotator cuffs, and restore the stability of the joints in a very small incision, with good efficacy, less risk, and fast recovery.
