Abstract:
The rotator cable and rotator interval are among the most recent topics of interest in current shoulder literature. Most of the research has been published in the last two decades and our understanding about the importance of these anatomical structures has improved with biomechanical studies, which changed the pre- and intra-operative approaches of shoulder surgeons to rotator cuff tears in symptomatic patients.The rotator cable is a thick fibrous bundle that carries the applied forces to the rotator cuff like a \'suspension bridge\'. Tears including this weight-bearing bridge result in more symptoms. On the other hand, the rotator interval is more like a protective cover consisting of multiple layers of ligaments and the capsule rather than a single anatomical formation like the rotator cable.Advances in our knowledge about the rotator interval demonstrate that even basic anatomical structures often have greater importance than we may have understood. Misdiagnosis of these two important structures may lead to persistent symptoms.Furthermore, some distinct rotator cuff tear patterns can be associated with concomitant rotator interval injuries because of the anatomical proximity of these two anatomical regions. We summarize these two important structures from the aspect of anatomy, biomechanics, radiology and clinical importance in a review of the literature. Cite this article: EFORT Open Rev 2019;4:56-62.

摘要:
旋转器电缆和旋转器间隔是当前肩部文献中感兴趣的最新主题之一。大多数的研究已经发表在过去的二十年,我们对这些解剖结构的重要性的理解已经提高了生物力学研究,这改变了有症状患者肩袖撕裂的肩关节外科医生的术前和术中方法。旋转电缆是一根厚的纤维束,将施加的力承载到肩袖上,就像“吊桥”一样。包括这个承重桥在内的眼泪会导致更多的症状。另一方面,旋转器间隔更像是由多层韧带和胶囊组成的保护盖,而不是像旋转器电缆那样的单个解剖结构。我们对旋转器间隔的知识的进步表明,即使是基本的解剖结构也往往比我们所理解的更重要。这两个重要结构的误诊可能导致持续症状。此外,一些不同的肩袖撕裂模式可能与伴随的旋转间期损伤相关,因为这两个解剖区域在解剖学上很接近。我们从解剖学的角度总结了这两个重要的结构,生物力学,在文献综述中的放射学和临床重要性。引用这篇文章:EFORTOpenRev2019;4:56-62。DOI:10.1302/2058-5241.4.170071。
