“…In the present study, the author detected that mCHL tears were concomitant with LHB subluxation or dislocation; However, the LHBs were stable in patients with an intact LHB pulley or SGHL lesions. Cadaveric et al have shown the mCHL to be the key ligament responsible for keeping the LHBT aligned within the tubercular groove [4,22]. Given the function of the SGHL and mCHL and pulley classi cation de ned by Habermeyer P [14], the author divided the LHB pulley lesions into three styles: intact, pulley fraying or SGHL lesions, and tear in the mCHL.…”

“…The rotator cuff interval is composed of the superior glenohumeral ligament (SGHL), the two coracohumeral ligaments (CHLs) and the glenohumeral joint capsule [1][2][3][4][5]. Jost [1] et al identi ed three layers of the interval: the deep layer, composed of the SGHL; the intermediate layer, composed of the two bundles of the CHL; and the super cial layer, formed by the SSP bers posteriorly and the SSC bers anteriorly[6-8].…”

Nakata [4] et al believed that the insertion of the mCHL and the superior CHL(sCHL) into the lesser tuberosity, together with the superior bers from the SSC tendon, act as a pulley for the LHB to stabilize the biceps tendon in the bicipital groove. Ryuzo Arai et al [9] and Andreas Werner et al [2] argued that the LHB pulley is the main structure that stabilizes the biceps tendon, while the transverse humeral ligament does not play a major role.…”

Background: Given the increasing anatomical study of the subscapular (SSC) tendon and its adjacent anatomical structure, the present study proposed a modified arthroscopic classification system. Methods: Between April 2018 and April 2021, 119 of 312 rotator cuff tears with isolated SSC tears or SSC tears associated with supraspinatus (SP) or infraspinatus tendon (IS) tears diagnosed by the author were considered potentially eligible for inclusion in this prospective study. In addition to routine arthroscopic examination, the present study carefully identified the SSC tear and adjacent long head biceps(LHB) and pulley as well as performed corresponding treatment according to the lesion. All procedures were performed by the author as a single surgeon. Results: This study modified SSC tears classification defined by Habermeyer Pinto eight types according to tears size and bicipital pulley lesions : Type I tears are located in the superior third of the first facet footprint of the SSC tendon; Type Ia tears accompany an intact LHB pulley or superior glenohumeral ligament(SGHL)lesion , while Type Ib tears accompany a medial coracohumeral ligaments(mCHL) tear or SGHL lesion. Type II tears are defined as the detachment of SSC exceeding one-third of the first facet footprint but not exceeding the whole; Type IIa tears accompany an intact LHB pulley or SGHL lesion, while Type IIb tears accompany a mCHL tear or SGHL lesion. Type III tears are defined as SSC detachment exceeding the first facet footprint but not exceeding the second facet footprint; Type IIIa tears accompany an intact LHB pulley or SGHL lesion, while Type IIIb tears accompany a mCHL tear or SGHL lesion. Type IV tears are defined as SSC detachment exceedingthe second facet footprint regardless of the tendon quality and retraction; Type IVa tears accompany an intact LHB pulley or SGHL lesion, while Type IVb tears accompany a mCHL tear or SGHL lesion Conclusions: On the basis of these observations, this modified arthroscopic classification of SSC tears was more concise and provided guideline according to tear type and obtained satisfactory early-and mid-stage clinical results.

“…The SGHL originates from the superior glenoid tubercle, running anteriorly to the LHB tendon and inserting into the lesser tuberosity. 6 7 The coracoglenoid ligament is a third ligament of the rotator interval, yet it does not appear to play a role in tendon stabilization. Nevertheless, magnetic resonance (MR) recognition of this ligament and its variants can be essential to avoid diagnostic pitfalls.…”

Anatomical variants of the long head of biceps (LHB) tendon are widely discussed in the literature. As one of the few intra-articular tendons, magnetic resonance arthroscopy can quickly evaluate the proximal part of LHB morphology. It provides good assessment of both intra-articular and extra-articular portions of the tendons. In-depth knowledge about imaging of the anatomical LHB variants discussed in this article is useful preoperatively for orthopaedists and also helps avoid potential diagnostic misinterpretations.

“…The biceps pulley is a capsuloligamentous complex that stabilizes the long head of the biceps brachii (LHB) tendon in the bicipital groove and opposes the anterior shearing stress in the rotator interval (Choi, Kim, Kim, & Lee, 2015; Nakata et al, 2011). The SGHL is a component of the rotator interval and macroscopically forms a U‐shaped anterior suspension around the LHB tendon.…”

The three glenohumeral ligaments (superior, middle, and inferior) are discrete thickenings of the glenohumeral joint capsule and are critical to shoulder stability and function. Injuries to this area are a cause of significant musculoskeletal morbidity. A literature search was performed by a review of PubMed, Google Scholar, and OVID for all relevant articles published up until 2020. This study highlights the anatomy, biomechanical function, and injury patterns of the glenohumeral ligaments, which may be relevant to clinical presentation and diagnosis. A detailed understanding of the normal anatomy and biomechanics is a necessary prerequisite to understanding the injury patterns and clinical presentations of disorders involving the glenohumeral ligaments of the shoulder.
