The patient was diagnosed with shoulder impingement syndrome after X-ray examination, which confirmed shoulder impingement and abnormal development of the acromion. After treatment with medication, closed injection and ultrashort wave therapy, the patient’s symptoms improved sufficiently and he gradually resumed his basic life. Basic information】Male, 60 years old 【Disease type】Shoulder impingement syndrome 【Hospital]Harbin No.1 Hospital 【Time of consultation】July 2021 【Treatment plan】Oral medication (celecoxib capsule)+Closed injection therapy (lidocaine hydrochloride injection, prednisolone acetate injection)+Physical therapy (ultrashort-wave treatment) 【Treatment cycle】Inpatient treatment for 7 days, outpatient follow-up 【Treatment effects Pain relieved and shoulder joint activity restored I. Initial consultation The patient is a 60-year-old man with a history of shoulder overactivity and shoulder pain as the main clinical symptom. The pain is mainly located in the lateral aspect of the acromion and can be dispersed to the area of the deltoid muscle stopping point. Initially, the pain appeared when the shoulder joint was in motion, and there was no pain when resting. With the development of the disease, the patient came to our hospital because he had pain at night and pain at rest, and he was unable to lie down on the affected side, and he was easily woken up with pain when he turned over in his sleep at night. The patient’s passive activities of the shoulder joint were normal, while active activities were limited. X-ray of the shoulder joint confirmed that the acromion was a type 2 acromion with abnormal development, and there were sclerosis of the humeral tuberosity and acromion, suggesting the existence of shoulder impingement syndrome. Since the onset of the disease was relatively short and the condition of the patient was relatively mild, hospitalization was considered, and conservative treatment was preferred to alleviate the clinical symptoms. After the onset of shoulder impingement syndrome, the patient suffered from significant pain in the shoulder joint, which affected his normal life, and the pain was more pronounced when the shoulder joint was flexed and abducted anteriorly. In order to alleviate the clinical symptoms, comprehensive conservative treatments were used during the 7-day hospitalization, such as the use of triangular scarf suspension brakes in the acute stage, limiting the shoulder joint forward flexion and elevation and abduction movements, and moving the shoulder joint appropriately several times a day to prevent adhesions. During hospitalization, the patient was given oral celecoxib capsules to eliminate inflammation and relieve pain. At the same time, the patient was treated with closed injections in the subacromial space, using lidocaine hydrochloride injection and prednisolone acetate injection; at the same time, ultrashort wave therapy was used to promote the reduction of inflammation. With the later shoulder joint muscle strength training, the shoulder joint function was restored. After 7 days of hospitalized conservative treatment, the patient’s shoulder impingement syndrome was significantly improved, and the clinical symptoms such as shoulder pain, radiating pain, limited shoulder joint movement, and shoulder joint weakness were significantly reduced, and the phenomenon of waking up with pain at night disappeared, and the patient’s basic ability to live was restored, and the patient was relatively satisfied with the treatment effect, and was allowed to be discharged from the hospital and go home. After conservative treatment, the patient was able to improve, for which I was very happy. However, the patient should be advised not to participate in heavy labor and competitive sports such as basketball, badminton and so on. In the case of not doing over-the-shoulder action, the patient can complete the rope skipping exercise and upper limb strength exercise such as dumbbell weight exercise biceps and triceps, but need to strictly limit the shoulder joint forward flexion lifting, abduction and other directional activities, and at the same time, strengthen the shoulder muscle strength training, improve the stability of the shoulder joint to prevent frequent shrugging action and acute trauma of the shoulder joint. In addition, patients should be instructed that if they have severe pain in the shoulder joint, limited shoulder joint activities and weakness in lifting the shoulder after discharge from the hospital, they need to go to the orthopedic clinic in time for follow-up, and take an MRI of the shoulder joint to confirm whether there is a rotator cuff tear. V. Personal perception Most patients with shoulder impingement syndrome are related to abnormal development of the acromion. Generally, if the acromion is type II, it is easy to impinge with the greater tuberosity of the humerus, thus damaging the subacromial bursa, rotator cuff and other tissues. However, since the degree of injury in this patient is not severe, conservative treatment is better for the time being. If the lesion recurs and continues to progress, it will be difficult to obtain a clear outcome with conservative treatment, and the patient will eventually face arthroscopic surgery to remove the acromioclavicular growth and repair the rotator cuff tissue. Enhanced protection of the shoulder joint in general is crucial to preventing the progression of the disease.
