Shoulder pain has always been a big misunderstanding, with the development of shoulder surgery in China in the past 20 years, joint surgeons gradually recognize the complexity of shoulder diseases, in fact, a large part of the causative factors of shoulder pain is rotator cuff injury, rather than the familiar periarthritis, of course, if the mention of periarthritis, I believe that the following life scenarios you must have experienced, when a slightly older people touch their shoulders and say their shoulder pain, and even the neighborhood aunt can give her diagnosis: I think you must have “frozen shoulder”, you have to shake your arm. When a slightly older person touches his shoulder and says that his shoulder hurts, even the neighboring women can give her diagnosis: I think you must have “frozen shoulder”, you have to shake your arm. Frozen shoulder is actually a very generalized concept, born in the era of shoulder joint disease without full understanding, by the limitations of medical technology, doctors can not figure out the cause of shoulder pain buckle a big hat — shoulder pain is frozen shoulder, but the impact of this big hat is very far-reaching, so as to cause the misunderstanding: shoulder joint pain = frozen shoulder. In fact, the concept of “frozen shoulder” in the common people’s mouth in the classification of the cause of shoulder pain should be shoulder adhesive capsulitis, contracture capsulitis, also known as frozen shoulder, frozen shoulder, condensed shoulder, fifty shoulders. Its incidence only accounts for about 10-20% of shoulder pain, and it is a self-limiting disease, most of which can be cured in 1-3 years, but there are still a small number of cases that cannot be cured by themselves, and they will have residual joint pain and functional limitation. With the deepening of modern medical research and the continuous understanding of shoulder joint diseases, we have found that more than half of the pain in the shoulder joint (60-70%) is caused by the rotator cuff injury, which we are going to introduce to you today. The occurrence of rotator cuff injury and is closely related to age, according to statistics, in the shoulder lesions in the rotator cuff lesions accounted for about 60% Lehman’s cadaver study found that in the age of 60 years of age, the incidence of rotator cuff full tear about 6%, 60 years of age and above the population can be as high as 30% of the incidence of partial tear is twice as much as the incidence of full tear. Rotator cuff injury is a very high incidence of a disease in the middle-aged and elderly population, most of the large tertiary hospitals joint specialists to rotator cuff injury to understand more fully, but many of the grassroots hospitals to rotator cuff injury disease awareness of the rotator cuff injury, rotator cuff injury diagnosis and treatment and even there are a lot of misunderstandings and even errors, such as frozen shoulder shoulder shoulder shoulder shoulder main treatment, which includes shoulder stretching exercise, commonly known as shaking the shoulder, and if this is a If this is a patient with rotator cuff injury of acromioclavicular impingement disease, taking this kind of shoulder shaking treatment will aggravate the condition and even cause the rotator cuff tear range to increase! A large number of rotator cuff injury patients are not correctly and timely diagnosis and treatment, to carry out the treatment of rotator cuff injury diagnosis and treatment and publicize the work of science and technology has become urgent.
