Shoulder pain is very common in daily life, and the diagnosis of frozen shoulder is well known to women and children. When people have shoulder pain, they think of frozen shoulder first, and even some orthopedic surgeons often use the term “frozen shoulder” to diagnose shoulder pain in a general way. At present, frozen shoulder seems to be a synonym for shoulder pain, and when people have shoulder pain, they are often labeled as having frozen shoulder, so they perform a wide range of shoulder movements. As a result of inappropriate shoulder motion, this causes shoulder pain to linger and suffer from long-term pain. The incidence of “true frozen shoulder” is not high. The diagnosis of “frozen shoulder” is like a “garbage can” and many shoulder pains are diagnosed as frozen shoulder. “Rotator cuff injuries are the most prevalent shoulder disorder, followed by subacromial impingement and shoulder instability. These three disorders together account for almost 70% or more of shoulder disorders. Other disorders include subacromial impingement, intra-articular free bodies, osteoarthritis, biceps tendonitis, and many other shoulder disorders. In addition, diseases outside the shoulder joint, such as cervical spondylosis and some tumor diseases, can also have shoulder pain and require attention. The main symptom of frozen shoulder is that the movement of the shoulder joint is limited and the upper limb cannot be lifted even with the help of others, especially the hand cannot touch the back of the head, which affects the combing action. In addition, it can be accompanied by pain, especially when moving to the maximum angle is obvious, and the pain is obvious at night and can wake up in pain. However, frozen shoulder is a self-limiting disease. Without treatment, after a few months or a year or more, most patients’ pain can disappear and joint function can be restored. The main causes of shoulder pain are rotator cuff injury and subacromial impingement syndrome. The shoulder joint is the most complex and flexible joint in the human body, and it is also the joint with the widest range of motion, which allows the hand to touch any part of the body itself due to shoulder movement. It is because of its complexity and flexibility that there is a diversity of conditions that are subject to injury. The anatomical structure of the shoulder joint is large at the head and small at the bottom, and the bony structure is very unstable. To maintain the stability of the shoulder joint, it needs the support and protection of the surrounding soft tissues such as ligaments, tendons, and joint capsule, etc. Among these tissue structures, the acromion can block the shoulder joint from shifting upward, and the rotator cuff can effectively stabilize the shoulder joint, so these parts are vulnerable to injury. When the shoulder joint is abducted, especially when the shoulder joint is abducted and flattened, the humeral head collides with the acromion, which affects the bursa in the shoulder joint area, resulting in an inflammatory response and pain at the shoulder joint. The pain is mainly chronic and dull, and it worsens during shoulder joint supination or abduction activities. The pain is mainly chronic and dull and worsens during supination or abduction of the shoulder joint. This condition is more likely to occur in the elderly, in people who often have to work with their upper extremities and in sports enthusiasts. It can lead to subacromial impingement during normal sports, such as badminton, aerobics, and swimming, if done incorrectly. Between the acromion and the humeral head, there is a rotator cuff consisting of four tendons that encircle the humeral head, which plays an important role in the movement and stability of the shoulder joint. During repeated impingement of the acromion and humeral head, the rotator cuff gradually degenerates, and in severe cases, rotator cuff tissue rupture occurs, worsening pain and severely affecting the patient’s quality of life. The incidence of rotator cuff injury increases with age. It is a very common degenerative disease of the shoulder joint in older people over the age of 60, with a prevalence rate of 60%, much higher than the so-called “frozen shoulder”. In addition, athletes, people with a history of shoulder trauma and those who often lift heavy objects are also prone to rotator cuff injuries. The main symptoms of rotator cuff injury are pain in the shoulder joint, waking up in the middle of the night or not being able to sleep due to pain, pain in the upper limb lifting, especially in the process of lifting and then lowering the pain, the pain is mainly in the front and outside of the shoulder joint, and the pain can radiate to the upper arm. Another symptom is that the upper extremity is weak when lifting, but can rely on the other upper extremity to help lift. Subacromial impingement and rotator cuff injury is a gradual process. If shoulder pain occurs, it is likely to be just subacromial impingement in the early stages, which can heal with conservative treatment and proper functional exercise. expansion. Myth 1: Shoulder joint pain does not affect your daily life, so you do not need to treat it and it will pass. This is a misconception. Pain in the shoulder joint is a signal from the body that the shoulder joint has a problem and needs to be treated. Myth 2: Shoulder joint pain can be improved through exercises such as “pulling the ring” and “wheeling the arm”. Exercise is very important for the recovery of shoulder joint disease, but “pulling the ring”, “wheeling the arm”, pulling the upper limb violently and carrying heavy objects by hand can cause more serious damage to the rotator cuff injury. Inappropriate exercise can aggravate the condition, so exercise must be done under the guidance of a professional doctor. Myth 3: It is enough to apply some pain medication or creams to treat shoulder pain. This situation is likely to cover up the condition and further aggravate the injury. Self-treatment is not recommended until your specialist gives you a clear diagnosis. Myth #4: Stop treatment as soon as it gets better. Patients with shoulder pain are treated for a longer period of time. Do not stop treatment immediately after getting better, you need to treat for a longer period of time to reduce the chance of recurrence. Myth #5: Think that shoulder pain is only a minor problem and does not require surgical treatment. If it is a rotator cuff injury, surgical suturing of the rotator cuff is required. It will not heal without suturing and will further aggravate. At present, the use of arthroscopic minimally invasive treatment, trauma has been very small, recovery is also fast, and there are few complications. For shoulder joint pain, you should first go to a hospital specialist for a clear diagnosis and effective treatment according to the diagnosis, and the results are generally good. For example, frozen shoulder will generally heal after rehabilitation and medication, while subacromial impingement is generally treated conservatively and will generally improve after physiotherapy, rehabilitation, medication and closure therapy, but rotator cuff injury will require surgical suturing of the rotator cuff to prevent further rotator cuff tears. At present, most of the shoulder joint diseases can be treated by shoulder arthroscopy, which improves the accuracy of the surgery from technology, not only reduces the patient’s pain and trauma, but also greatly improves the prognosis of recovery. At the same time, with the postoperative exercises, the patient’s recovery effect is remarkable.
