Many middle-aged and elderly people are troubled by “senior shoulder”, but do you know what kind of disease is senior shoulder? Elderly shoulder is also known as periarthritis of the shoulder joint (hereinafter referred to as periarthritis), which is commonly known as frozen shoulder and fifty shoulders. It is a chronic specific inflammation of the shoulder joint capsule and its surrounding ligaments, tendons, and bursa, which is characterized by gradual onset of pain in the shoulder, which is more severe at night and worsens gradually, limitation of shoulder joint movement, and gradual relief after reaching a certain level, until complete recovery in the end. Frozen shoulder is a common condition characterized by pain and immobility of the shoulder joint. Possible Effects of Frozen Shoulder Many people in their middle age will experience symptoms of limited shoulder movement, but most people do not have a deep understanding of this condition and do not pay attention to it. In fact, if frozen shoulder is not effectively treated, it may seriously affect the functional activities of the shoulder joint. The shoulder joint may have extensive pressure and pain, and radiate to the neck and elbow, and there may also be different degrees of atrophy of the deltoid muscle. Causes of frozen shoulder 1, shoulder causes (1) most of the disease occurs in the middle-aged and old people over 40 years old, soft tissue degeneration, the ability to withstand all kinds of external forces is weakened; (2) long-term over-activity, poor posture, etc. produced by chronic traumatizing force; (3) upper extremity trauma shoulder fixed for too long, periapical tissues secondary atrophy, adhesion; (4) acute contusion of the shoulder, traction injuries, due to improper treatment, and so on. 2.Factors outside the shoulder Cervical spondylosis, heart, lung, biliary tract diseases occurring in the shoulder involved in pain, because of the primary disease for a long time does not heal the shoulder muscle persistent spasm, ischemia and the formation of inflammatory foci, transformed into a real frozen shoulder. Clinical manifestations of frozen shoulder (1) shoulder pain: most of the chronic episodes of shoulder paroxysmal pain, and then the pain gradually worsened or dull pain, cutting pain, and was persistent, climate change or exertion often make the pain worse, when the shoulder accidentally by the collision or pulling, often can cause tear-like pain, shoulder pain day light and night heavy for this disease is a major feature, if the pain caused by cold, it is particularly sensitive to climate change. (2) Restriction of shoulder joint activities: Shoulder joint activities in all directions can be restricted, abduction, supination, internal and external rotation are more obvious, with the progression of the disease, due to the adhesion of the joint capsule and the soft tissues around the shoulder caused by the long-term disuse, the muscle strength gradually decreases, and the active and passive activities of the shoulder joint in all directions are restricted, and the function of elbow joint can be affected in serious cases, and the hand can not feel the same side of the shoulder when flexing the elbow, especially when the arm is extended back. Especially when the arm is extended back, the elbow flexion movement cannot be completed. (3) Fear of cold: the patient is afraid of cold in the shoulder. (4) Pressure pain: Most patients can feel obvious pressure points around the shoulder joint. (5) Muscle spasm and atrophy: Early spasm of the deltoid and supraspinatus muscles and other peripheral muscles of the shoulder may occur, and in the late stage, wasting muscle atrophy may occur, resulting in typical symptoms such as shoulder peak protrusion, inconvenience in lifting, and inability to extend the shoulder backward, and then the symptoms of pain will be reduced. What examination should be done? X-ray examination and MRI examination of shoulder joint are mainly used for this disease. Treatment At present, the main treatment for frozen shoulder is conservative treatment. Oral anti-inflammatory and analgesic drugs, physical therapy, local closure of pain points, massage and massage, self-massage and other comprehensive therapy. At the same time, joint function exercises are carried out, including active and passive abduction, rotation, extension and flexion, and circular rotation movements. When the shoulder pain is significantly reduced and the joint is still stiff, the joint can be released under general anesthesia to restore the range of motion of the joint.
