Frozen shoulder, also known as periarthritis, is a chronic inflammatory reaction of the shoulder joint and surrounding soft tissues. If there are adhesions in the shoulder joint and the surrounding muscles, joint capsule, ligaments and other structures, it will lead to limited shoulder joint movement and inability to lift the arm. Frozen shoulder should seek medical treatment in time, and physiotherapy, medication and surgery can be carried out according to the specific situation. 1. Physiotherapy: clinically, ultra-short wave and intermediate frequency electricity are used to increase local blood flow, promote inflammation to subside and relieve pain. At the same time, the shoulder joint can be protected with a sling and rest can be paid attention to, so as to promote the inflammation to subside and the repair of shoulder joint tissues. 2. Medication: For the treatment of frozen shoulder, oral non-steroidal anti-inflammatory drugs such as ibuprofen and meloxicam can be taken to reduce inflammation; in severe cases, oral muscle relaxants can be taken to improve the stiffness of the shoulder joint; closure therapy can also be carried out, and glucocorticosteroids or local anesthetics can be injected locally to alleviate the inflammation and release the muscle spasm. 3. Surgical treatment: For patients who are ineffective in conservative treatment, arthroscopic adhesion release surgery is recommended to loosen the adhesive fibers under arthroscope to improve the function of shoulder joint. If you have frozen shoulder and can’t lift your arm, it is recommended that you seek medical advice in time, and under the guidance of your doctor, you can have appropriate treatment and rehabilitation according to your condition.
