He came to the orthopedic department recently to find out that his shoulder pain was not a frozen shoulder, but a rotator cuff tear, which required surgery. After the surgery, Wang’s shoulder pain improved rapidly and he was recently discharged from the hospital through the functional training of the rehabilitation department. It is often seen in the clinic that about 30% of patients over 60 years old have rotator cuff injury, mainly due to acute tearing injury and chronic strain. These patients often show pain and stiffness in the shoulder joint when moving, and the pain is obviously the same as the performance of frozen shoulder when resting or at night, and many patients and even doctors treat it as a problem of frozen shoulder, which results in poor efficacy and patients The more you treat it, the more it hurts. Dr. Li Yonggang, the chief physician, analyzed that although the symptoms of rotator cuff injury and frozen shoulder are very similar, the treatment methods are completely different. Frozen shoulder is generally self-limiting and requires shoulder joint activities under the guidance of a doctor to accelerate blood supply and improve inflammatory symptoms. Rotator cuff injuries, on the other hand, tear tendon fibers and even rupture them, requiring surgical repair with sutures. In the case of rotator cuff injury, it is necessary to keep the shoulder at absolute rest, not to move it, and to take care of it to restore the degree of muscle damage. If a patient with a rotator cuff tear is mistaken for “frozen shoulder” and allowed to continue to exercise such as “climbing the wall” or artificially and forcibly loosening the shoulder joint, the rotator cuff tear may continue to expand and eventually form a huge or irreparable rotator cuff tear and lose the opportunity for surgery. The opportunity for surgery is lost. Minimally invasive arthroscopic treatment is now available to suture the torn rotator cuff tissue, resulting in significant improvement in patient symptoms and function. The chief physician emphasized that many patients treat shoulder pain as frozen shoulder whenever it occurs, but in fact, the treatment for each part of the shoulder varies, with some requiring functional exercises to prevent adhesions and others requiring surgery. In addition, tuberculosis, shoulder tumors and malignant tumors in the upper and lower mediastinum can also cause shoulder pain, so a specialist needs to identify them through hand posture and imaging data to avoid delaying the best treatment time. It is recommended not to use the shoulder joint excessively, especially the bladder shaking exercise should be carefully measured, and it is best not to overdo the shoulder exercise to avoid causing damage to the shoulder.
