MR arthrography of the glenohumeral joint. Stoller D W Radiologic clinics of North America This article explores MR arthrography of the glenohumeral joint, including normal anatomy of the glenoid labrum, glenohumeral ligaments, and biceps labral complex. Examples of glenohumeral joint instability include the Bankart lesion, anterior labroligamentous periosteal sleeve avulsion, glenolabral articular disruption, humeral avulsion of the glenohumeral ligament, and Bennet lesion. Normal variations include the sublabral foramen, the Buford complex, and cord-like middle glenohumeral ligament. Labral tears and paralabral cysts are also discussed.

Arthroscopic anatomy, variants, and pathologic findings in shoulder instability. Tischer Thomas,Vogt Stephan,Kreuz Peter C,Imhoff Andreas B Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association Shoulder instability is a common diagnosis that often requires surgical treatment. A detailed knowledge of the shoulder anatomy and its stabilizing structures is of utmost importance for successful treatment of shoulder instabilities. Identifying anatomic variants (e.g., sublabral hole, meniscoid labrum, cordlike middle glenohumeral ligament, and Buford complex) and distinguishing them from pathologic findings may be especially difficult, as shown by the high interobserver variability. Over the last decade, basic research and arthroscopic surgery have improved our understanding of the shoulder anatomy and pathology. In the context of shoulder instability, injuries of the glenoid (bony Bankart), injuries of the glenoid labrum superiorly (SLAP) or anteroinferiorly (e.g., Bankart, anterior labroligamentous periosteal sleeve avulsion, and Perthes), capsular lesions (humeral avulsion of the glenohumeral ligament), accompanying cartilage lesions (Hill-Sachs, glenolabral articular disruption), and rotator interval and pulley lesions, as well as signs of dynamic instability impingement (posterior-superior impingement, anterior-superior impingement) can be exactly diagnosed (magnetic resonance imaging with intra-articular gadolinium, arthroscopy) and treated (arthroscopy). Therefore the purpose of this article is to review the current literature concerning shoulder anatomy/pathology related to shoulder stability/instability to improve clinical diagnosis and surgical treatment of our patients. 10.1016/j.arthro.2011.05.017

Arthroscopic "Panorama" View of the Subacromial Space via Deltoid Fascia Release. Yalizis Matthew,Kruse Kevin,Godenèche Arnaud Arthroscopy techniques Proper visualization is of paramount importance during arthroscopic rotator cuff repair. We propose a technique that significantly improves the visualization of the rotator cuff when viewing from the anterolateral or lateral portals. This "panorama" view is obtained by a release of the deep layer of the deltoid fascia, which in turn increases the space between the humerus and the deltoid muscle. This release increases the volume of the subdeltoid bursa, secondarily increasing the field of view of the subacromial space with the camera viewing from the anterolateral or lateral portals. This technical note describes a new technique useful in obtaining an excellent view of the subacromial space proving very useful in both the diagnosis and treatment of rotator cuff pathology. 10.1016/j.eats.2016.04.016
