Abstract: 【Abstract】〓Subacromial impingement syndrome is a common shoulder joint disease. Though there are different causes of diseases like scapulohumeral periarthritis, the clinical symptoms, treatment and prognosis of Subacromial impingement syndrome are quite different. As a result, these diseases are often mixed up in clinical practice. Through cadaver studies, Neer first put forward the concept of subacromial impingement syndrome and divided into three phases according to pathology. In phase I and phase II, conservative treatment is commonly applied, for example, taking non-steroid anti-inflammatory drug and partial closure could achieve good results. However, for phase III patients or patients to whom phase I and phase II treatment are ineffective. Surgery is required. With the development of science and technology, acromioplasty raised by Neer as a surgical method has been replaced by arthroscopic subacromial decompression.
