Lao Zhou is 46 years old, working in an institution, people in middle age, he gradually often feel that the physical condition is not as good as before. This is not, the last year or two, the right shoulder joint and inexplicably pain up, such as sitting properly there is nothing, but as long as the right arm up a lift, it is simply sore and painful it! Later, dressing and undressing, changing a light bulb would hurt and make my body sweat. Later, when washing my hair, I felt an itchy feeling on the back of my neck, and when taking objects from high places, I felt a sharp pain from lifting my arm. “What’s wrong? It must be frozen shoulder, others always say this is office syndrome? It seems to strengthen the exercise.” The old week is a basketball fan, has been the unit basketball team’s main guard it. The reason for this is the suspicion that you have got “frozen shoulder” from sitting in the office, the old week is determined to strengthen their physical exercise, not only playing basketball, but also often swimming, playing badminton and so on. I thought this could reduce the symptoms, I did not think, the pain and itching more serious, the old week only to the hospital to seek medical help, a year, Chinese medicine, Western medicine to see a lot, soup, ointment also used a lot, but also follow the doctor’s instructions every day at home to practice “climbing the wall”, and ultimately? Still no effect, the condition has not improved at all. This period of time will even wake up in the middle of the night in pain. Long-term suffering from the pain of the old week feel overwhelming anxiety, recently he made an MRI examination, after the diagnosis of the old week is the shoulder peak impingement syndrome. Shoulder impingement syndrome? Why would the shoulder joint impingement? Do shoulder joints still fight with each other? It depends on the structure of the human shoulder joint. The shoulder joint is made up of the humeral head at the upper end of the upper arm bone and the scapular glenoid at the upper end of the outer scapula. When the shoulder joint is active, the scapular glenoid is relatively fixed while the humeral head rotates continuously within the scapular glenoid. Between the humeral head and the scapular glenoid is an arched joint capsule that extends slightly beyond the circumference of the shoulder joint, and the upper part of the overlying humeral head is called the acromion. There is also a gap between the acromion and the humeral head, and there are tendons in the gap that play an extremely important role in the movement of the shoulder joint. When the shoulder joint is used for abduction activities (various activities that often involve lifting), repeated friction and impact between the structures in the subacromial space and the rostral arch can cause inflammation and degeneration of the subacromial tissues and even rotator cuff tears, resulting in shoulder pain and dysfunction, which is the origin of acromion. Depending on the affected tissues, it can be manifested as subacromial bursitis, supraspinatus, supraspinatus calcification, rotator cuff injury and biceps tendonitis. The main pathological changes are the narrowing of the subacromial space or the repetitive limitation of the shoulder joint mobility, which leads to fatigue and micro-injury of the rotator cuff and scapular band muscles. Impingement syndrome is more common in young athletes and middle-aged adults. Frequent overhead lifters, swimmers, baseball and tennis players, as well as construction workers and painters are particularly susceptible. And the beginning symptoms may be mild, and early patients do not seek medical attention. Initially, pain may occur with activity, and the pain may radiate from the shoulder to the forearm and be exacerbated by lifting or holding objects. As the pain progresses, nocturnal pain may develop. The pain may also reduce the strength or range of motion of the upper extremity and prevent the athlete from putting his or her hands behind the back to “buckle and unbuckle”. What should I do if I have impingement syndrome? In the early stage, patients can be treated conservatively by rest, ice, local closure and muscle strengthening exercises. Non-surgical treatment is very effective in the early stages of the disease. However, if conservative treatment is ineffective or the symptoms are more severe, surgical treatment can be used to remove the cause of impingement, such as arthroscopic acromioplasty. Of course, if the rotator cuff is torn, then rotator cuff repair can only be performed. It is important to note that patients suffering from impingement syndrome must strive for early diagnosis and treatment, and should not follow the treatment method of “frozen shoulder” as a matter of course, so as not to delay the condition and lose the best time for treatment, or even cause lifelong regret.
