Frozen shoulder is usually a sterile inflammatory reaction, usually caused by soft tissue degeneration, too long immobilization of the shoulder joint after trauma, muscle spasm, chronic injury, etc.; it often leads to pain around the shoulder joint, and with the progression of the disease, the shoulder joint will also have limited activities, unable to lift the arm and other manifestations, and may lead to the patient’s muscle atrophy. X-rays, MRI (magnetic resonance imaging) and shoulder arthrography are usually required to confirm the diagnosis, and based on the results of these tests, the severity of the patient’s condition can be determined, and a more individualized treatment plan can be formulated.
