“…(Pouliart et al 2007 ) Additionally, the wide attachments of the joint capsule have been reported to be related with the stabilizing structures of the elbow and knee joints. (Nasu et al 2017 ; Shimura et al 2016 ) In the current study, we further demonstrated that the articular capsule, compared to other areas, had a wider attachment on the humerus from the inferior edge of the subscapularis insertion to the inferior edge of the teres minor insertion, where no rotator cuff tendons insert. The glenohumeral joint has been well known as the inherently unstable joint, and thought to be stabilized by the interaction between the static, including the labrum and capsule, and dynamic, including musculotendinous structures.…”

BackgroundAlthough conventional Bankart repair has been the accepted procedure for traumatic anterior glenohumeral instability, the humeral avulsion of the glenohumeral ligament or an elongation of the capsule remains challenging to decide the appropriate treatment. The anatomical knowledge regarding the whole capsule of glenohumeral joint is necessary to accurately treat for the capsular disorders. The aims of the current study were to investigate the anatomical features of capsular attachment and thickness in a whole capsule of glenohumeral joint.MethodsWe used 13 shoulders in the current study. In 9 shoulders, we macroscopically measured the attachment widths of the capsulolabrum complex on the scapular glenoid, and the attachment widths of the capsule on the humerus in reference to the scapular origin of the long head of triceps brachii, and the humeral insertion of the rotator cuff tendons. We additionally used 4 cadaveric shoulders, which were embalmed using Thiel’s method, for the analysis of the thickness in a whole capsule by using micro-CT.ResultsThe glenoidal attachment of the articular capsule appeared to have a consistent width except for the superior part of the origin of the long head of triceps brachii. On the humerus, the articular capsule was widely attached to areas without overlying rotator cuffs, with the widest width (17.3 ± 0.9 mm) attached to the axillary pouch. The inferior part of the capsule, which was consistently thicker than the superior part, continued to the superior part along the glenoid and humeral side edge.ConclusionsThe current study showed that the inferior part of the glenohumeral capsule had a wide humeral attachment from the inferior edge of the subscapularis insertion to the inferior edge of the teres minor insertion via the anatomical neck of the humerus, and the thickness of it was thicker than the superior part of the capsule.

“…However, previous studies had not identified the width of the capsular attachment, which should underlie the anterior bundle. Meanwhile, at the lateral side of the proximal ulna, Shimura et al () previously showed that there were no 6‐mm attachment on the cartilage surface of the coronoid tip and 12 mm length attachment of the joint capsule at the lateral side of the coronoid process. In the current study, we found the capsular attachment on the ST with approximately 7 mm width, which was wider than previously thought.…”

“…However, the location of the attachment area of the anterior bundle of the UCL on the sublime tubercle (ST) remains controversial (Timmerman and Andrews, ; Cage et al, ; Munshi et al, ; Dugas et al, ). Meanwhile, a previous study reported that the capsule of the anterior elbow joint had substantial attachment width in the sagittal direction, and the cartilage surface did not have the capsular attachment at the tip of the coronoid process (Shimura et al, ). However, in the medial elbow joint, the attachment of the underlying capsule and the layered relationship between the UCL and the joint capsule have been rarely analyzed.…”

To improve the management outcomes and diagnostic accuracy of the ulnar collateral ligament (UCL) injury, the anatomy of the medial side of the elbow joint is necessary to be understood in terms of the periarticular surroundings rather than the specific ligaments. The aim of this study was to anatomically clarify the medial side of the elbow joint in terms of the tendinous structures and joint capsule. We conducted a descriptive anatomical study of 23 embalmed cadaveric elbows. We macroscopically analyzed the relationship between the flexor pronator muscles (FPMs) and the joint capsule in 10 elbows, histologically analyzed in 6 elbows, and observed the bone morphology through micro computed tomography in 7 elbows. The two tendinous septa (TS) were found: between the pronator teres (PT) and flexor digitorum superficial (FDS) muscles, and between the FDS and flexor carpi ulnaris (FCU) muscles. These two TS are connected to the medial part of the brachialis tendon, deep aponeurosis of the FDS, and FCU to form the tendinous complex, which linked the humeroulnar joint and could not be histologically separated from each other. Moreover, the capsule of the humeroulnar joint under the tendinous complex had attachment on the ST of 7 mm width. The two TS, the brachialis tendon, the deep FDS and FCU aponeuroses, and the joint capsule linked the humeroulnar joint. These anatomical findings could lead to a paradigm shift in the prevention, diagnosis, and treatment of UCL injuries in baseball players. Clin. Anat. 32:379–389, 2019. © 2018 The Authors.

“…The total cartilage and bone thickness proximal to the capsule was 4.7e5.9 mm. 29,30 The anterior capsule of the elbow joint had a substantial attachment at the radial side (11.9 ± 2.2 mm) of the coronoid compared to that at the ulnar side (6.1 ± 1 mm). 16 The O'Driscoll classification of coronoid tip fracture divide the tip fracture into subtype 1 of tip fractures involving 2 mm of the coronoid, and subtype 2 of tip fractures involving >2 mm.…”

The anatomy of the elbow joint had been studied extensively over the last 2 decades. The increased understanding of the anatomy and contribution of the anatomical structures to the elbow biomechanics had enabled surgeons to improve the results of surgical reconstruction and fracture fixation. This review articles intend to summarise the salient functional and clinical anatomical and relevant biomechanical data that had been published recently.
