“…The pectoralis major, the coracobrachialis and the short head of the biceps femoris were amputated from the edge of the coracoid. The RI was exposed after all fatty tissues underneath the coracoacromial ligament and the subacromial bursa were dislodged, and the RI and its adjacent structures were observed [6]. The ending point of the coracoid below the CHL was revealed after the coracoacromial ligament was dislodged, the free edge of the CHL was dissected along the ending point of the coracoid until the ending point of the humerus was reached and the undersurface was cut from the articular capsule along the edge [26].…”

“…Daly et al suggested that an additional RI closure improves the biomechanical strength of the repaired subscapularis tendon. 37 Furthermore, Mologne et al put forward the idea that anterior shoulder stability increases with the same closure. 38 A study by Tsai et al showed good clinical results with arthroscopic release of the RI in adhesive capsulitis patients.…”

Rotator cable and rotator interval: anatomy, biomechanics and clinical importance

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.

The deltopectoral exposure has earned the reputation as the "workhorse" approach to the shoulder. Due to the reproducible anatomy and its extensile nature, there is little debate when considering exposure in total shoulder arthroplasty (TSA). Despite this consensus, there is still significant variability in management of the subscapularis. Several repair techniques including a subscapularis tenotomy, peel, and lesser tuberosity osteotomy (LTO) have been developed to ensure healing and optimize function. This article focuses on performing a LTO in anatomic TSA. We will review the surgical technique and advantages in exposure in addition to biomechanical and clinical outcomes.
