The impingement syndrome is a clinical entity characterized by shoulder pain due to primary or secondary mechanical irritation of the rotator cuff. The primary factors for the development of impingement are a curved or hook-shaped anterior acromion as well as subacromial osteophytes, which may lead to tearing of the supraspinatus tendon. Secondary impingement is mainly caused by calcific tendinopathy, glenohumeral instability, os acromiale and degenerative changes of the acromioclavicular joint. Conventional radiographs are initially obtained, mainly for evaluation of the bony structures of the shoulder. If available, sonography can be used for detection of lesions and tears of the rotator cuff. Finally, MR-imaging provides detailed information about the relationship of the acromion and the acromioclavicular joint to the rotator cuff itself. In many cases however, no morphologic cause for impingement syndrome can be found. While patients are initially treated conservatively, chronic disease usually requires surgical intervention.
撞击综合征是一种临床病症，其特征为由于肩袖的原发性或继发性机械性刺激而导致肩部疼痛。撞击发生的主要因素是弯曲或钩状的前肩峰以及肩峰下骨赘，这可能导致冈上肌腱撕裂。继发性撞击主要由钙化性肌腱病、盂肱关节不稳定、肩峰骨和肩锁关节的退行性改变引起。最初会进行传统X线摄影，主要用于评估肩部的骨质结构。如有条件，超声检查可用于检测肩袖的病变和撕裂。最后，磁共振成像可提供有关肩峰和肩锁关节与肩袖本身关系的详细信息。然而，在许多情况下，无法找到撞击综合征的形态学病因。虽然患者最初采用保守治疗，但慢性病通常需要手术干预。
