The coracoacromial ligament is a flat triangular band that plays a supportive role for the shoulder joint. The coracoacromial arch is formed (anteriorly to posteriorly) by the coracoid process, coracoacromial ligament, and acromion. It is thought that decreased space within the.

Bone loss in anterior instability. The muscles in relation with the joint are, above, the Supraspinatus; below, ,igamento long head of the Triceps brachii; in front, the Subscapularis; behind, the Infraspinatus and Teres minor; within, the tendon of the long head of the Biceps brachii.
The humerus is flexed drawn forward by the Pectoralis major, anterior fibers of the Deltoideus, Coracobrachialis, and when the forearm is flexed, by the Biceps brachii; extended drawn backward by the Latissimus dorsi, Teres major, posterior fibers of the Deltoideus, and, when the forearm is extended, by the Triceps brachii; it is abducted by the Deltoideus and Supraspinatus; it is adducted by the Subscapularis, Pectoralis major, Latissimus dorsi, and Teres major, and by the weight of the limb; it is rotated outward by the Infraspinatus and Teres minor; and it is rotated inward by the Subscapularis, This definition incorporates text from a public domain edition of Gray’s Anatomy 20th U.
Anatomical terminology [ edit on Wikidata ]. The arteries supplying the joint are articular branches of the anterior and posterior humeral circumflex, and transverse scapular.

In human anatomy, the glenohumeral ligaments GHL are three ligaments on the anterior side of the glenohumeral joint i. During rotation of the arm lateral rotation stretches all three ligaments while medial rotation relaxes them.
Dorsal carpometacarpal Coracohumeal carpometacarpal thumb: Retrieved from ” https: The ligaments may be best seen by opening the capsule at the back of the joint and removing the head of the humerus: There are usually three openings in the capsule. The radius of curvature of the head of the humerus is greater superiorly than inferiorly, which further stretches these ligaments so that they keep the articular surfaces of the joint in their close-packed position.
Acromioclavicular Coracoclavicular trapezoid conoid. Volume One Upper Limb 5th ed. By rotating the humerus laterally, this contact is delayed because the greater tubercle is pulled back so that the bicipital groove faces the coracoacromial ligament.

In addition to these, coracohujeral capsule is strengthened in front by two bands derived from the tendons of the Pectoralis major and Teres major respectively.
It is strengthened, above, by the Supraspinatus; below, by the long head of the Triceps brachii; behind, by the tendons of the Infraspinatus and Teres minor; and in front, by the tendon of the Subscapularis.

Languages Galego Edit links. Articular capsule Glenoid labrum Glenohumeral ligaments Coracohumeral ligament Transverse humeral ligament The articular capsule completely encircles the joint, being attached, above, to the circumference of the glenoid cavity beyond the glenoidal labrum; below, to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent.
During abduction the greater tubercle of the humerus comes in contact with the upper margin of the glenoid cavity, which limits maximum abduction. Wikipedia articles incorporating text from the 20th edition of Gray’s Anatomy Ligaments of the upper limb.
The Deltoideus covers the articulation in front, behind, and laterally. The articular cartilage on the head of the humerus is thicker at the center than at the circumference, the reverse being the case with the articular cartilage of the glenoid cavity.
Evolving concept of bipolar bone loss and the Hill-Sachs lesion: The tendon of the coracohumersl head of the Biceps brachii passes through the capsule and is enclosed in a tubular sheath of synovial membrane, which is reflected upon it from the summit of the glenoid cavity and is continued around the tendon into the intertubercular groove as far as the surgical neck of the humerus.

The bones entering into its formation are the hemispherical head of the humerus and the shallow glenoid cavity of the scapula, an arrangement which permits of very considerable movement, while the joint itself is protected against displacement by the tendons which surround it.
The articular capsule completely encircles the joint, being attached, above, to the circumference of the glenoid cavity ligwmento the glenoidal coracouumeral below, to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent.

Sternoclavicular Anterior sternoclavicular Posterior sternoclavicular Interclavicular Costoclavicular. The tendon thus traverses the articulation, but it is not contained within the synovial cavity. The ligaments do not maintain the joint surfaces in apposition, because when they alone remain the humerus can be separated to a considerable extent from the glenoid cavity; their use, therefore, is to limit the amount of movement.
