Impingement syndrome is an ill-defined term for a variety of disorders of the shoulder that manifest as anterior shoulder pain, especially during overhead activities. These disorders each have a common pathologic course that includes rotator cuff tendinitis (RCT), and, if untreated, may proceed to cuff rupture. RCT has at least two distinct etiologies. Primary impingement of the supraspinatus tendon on the coracoacromial arch is responsible in the majority of nonathletic cases. Overhead movements in sports are prone to developing secondary mechanical impingement because of an instability pattern that is common in this population. Information from this review and clinical practice permits differentiation of the two distinct etiologies of RCT which is important in treatment planning. Much work still needs to be done in defining the microscopic pathology of RCT.
撞击综合征是一个定义不明确的术语，用于描述多种肩部疾病，这些疾病表现为肩部前方疼痛，尤其是在进行过头活动时。这些疾病都有一个共同的病理过程，包括肩袖肌腱炎（RCT），如果不治疗，可能会发展为肩袖破裂。RCT至少有两种不同的病因。在大多数非运动员病例中，主要是冈上肌腱在喙肩弓上的原发性撞击。由于这种人群中常见的不稳定模式，运动中的过头动作容易发展为继发性机械性撞击。这篇综述和临床实践中的信息有助于区分RCT的两种不同病因，这在治疗计划中很重要。在确定RCT的微观病理学方面仍有许多工作要做。
