Just to ensure everything is clear, the ligaments associated with the shoulder joint include the: Coracoacromial Ligament; Superior Transverse Scapular Ligament The coracohumeral ligament consists of two bands that bridges the,The transverse humeral ligament transforms the.Just to ensure everything is clear, the ligaments associated with the shoulder joint include the:At the humeroulnar joint, the ulnar collateral ligament is a three-part triangular structure whose anterior component is stronger and more taut than the posterior part. Group. It encloses the tendon of the long head of biceps brachii and its sheath in the bicipital groove, forming a tunnel thus preventing it from subluxing out of the groove during shoulder movement. There is a superior, middle and inferior ligament that gives additional anteroinferior support to the joint capsule. The transverse humeral ligament (also know as the Brodie ligament) is a small broad ligament that extends between the lesser and greater tubercles of the humerus superior to the epiphyseal line. Conclusion: due to both macroscopic, but especially microscopic examination, we concluded that transverse humeral ligament does not exist as a distinct structure. Sprains are classified based on the severity of the tear:It should be noted that grade 1 and 2 sprains usually undergo,The most common aetiological factor associated with acute sprains at both the shoulder and elbow joints is a.Injuries to the elbow are usually associated with exaggerated valgus (away from the midline) or varus (towards the midline) forces that overcome the tenacity of the collateral ligaments of the elbow. Unlike traditional ligaments, the glenohumeral ligaments are not purely tensile.
