”Frozen shoulder” is the abbreviation of “periarthritis of the shoulder joint”, also known as “adhesive capsulitis”, commonly known as “fifty shoulder It is also known as “frozen shoulder”, “frozen shoulder”, “frozen shoulder”. From the name of the disease, we can understand the basic situation of the disease: it is called “periarthritis” and “adhesive capsulitis” because the disease is not a problem with the bones of the shoulder joint itself, but with the soft tissues around the shoulder joint (the joint capsule, bursa, and muscles). It is because the soft tissues around the shoulder joint (joint capsule, bursa, tendons, muscles, etc.) have become adherent inside and outside the joint due to age-related degeneration and aseptic inflammation, resulting in restricted movement of the shoulder joint, and the shoulder, which normally moves freely, seems to be frozen, so it is imaginatively called “frozen shoulder” or “frozen shoulder”. It is also known as “frozen shoulder” and “frozen shoulder”, because it occurs in middle-aged and elderly people around 50 years old. The main manifestation of this disease is pain and limited movement of the shoulder joint. The pain is usually light at the beginning, but gradually worsens. In severe cases, the pain is unbearable when touched slightly, and it is often difficult to sleep or wake up at night with pain. The diagnosis of this disease is not difficult, and it is mainly distinguished from shoulder pain caused by cervical spondylosis. Although the disease may not heal on its own, the natural course of the disease can take weeks to months, and the patient has difficulty tolerating the pain. There are many treatment methods, such as oral analgesics, physiotherapy, massage, acupuncture, local closure, small acupuncture, functional exercises, etc. However, the most effective method is to release the adhesions by manipulation under brachial plexus nerve block. This method is less painful (completely painless during release) and quicker (you can move freely after a manual release), and most patients can be cured at once.
