Frozen shoulder, also known as frozen shoulder, is a chronic, specific inflammation of the ligaments, tendons, bursa and other soft tissues surrounding the shoulder joint, resulting in shoulder pain and limited movement. The symptoms are usually slow in progression and self-limiting, and some patients may gradually disappear on their own and recover joint function. However, with the development of medical diagnostic techniques and improved understanding, the diagnostic term “frozen shoulder” is becoming less and less used, and many cases of frozen shoulder can be found to have a definite cause and a separate and accurate diagnosis. Therefore, there is no such thing as the fastest treatment for frozen shoulder, but the first step is to clarify the corresponding diagnosis. 1.Early treatment: For patients in the acute stage, they should go to a hospital specialist for examination, including physical examination, X-ray or even MRI and laboratory tests to clarify the cause of the so-called frozen shoulder. Depending on the specific situation, health education, braking, avoiding strain causes such as domestic activities, non-steroidal anti-inflammatory and blood-stasis activating drugs, etc. can be used for treatment; physical therapy requires the selection of reasonable methods to avoid aggravation of pain due to self-heating. In addition, according to the development of the disease at the follow-up examination, appropriate activities should be directed to avoid adhesions, etc. For frozen shoulder with no structural damage and a clear diagnosis, functional exercise and rehabilitation training can be performed under the guidance of a doctor. 2.Surgical treatment: In the advanced state of pure and true frozen shoulder, surgical treatment is rarely performed in general. Now, with the development of disease awareness and imaging, and the advancement of minimally invasive arthroscopic technology, surgical treatment is feasible for patients with so-called “frozen shoulder” (shoulder impingement syndrome, rotator cuff injury, etc.) whose non-surgical treatment is ineffective and whose indications are clear, in order to relieve shoulder pain and restore joint mobility with better efficacy.
