The coxal joint is a ball-and-socket joint, in which the head of the humerus articulates with the glenoid cavity of the scapula. Normalizing abnormal glenoid version is often a critical step in glenohumeral reconstruction. The main function of the rotator cuff is to stabilize and center the humeral head in the joint socket, the glenoid cavity. The remaining corner of the scapula, between the superior and lateral borders, is the location of the glenoid cavity (glenoid fossa). The glenohumeral joint has a profound range of motion due to the lack of bony restraint, the large surface area of the humeral head, and the relatively small glenoid area. Pick a style below, and copy the text for your bibliography. " The radiological assessment included an anteroposterior view and a CT scan that guided the surgical approach by indicating that the fragment of the glenoid cavity was especially dorsal. The glenoid labrum is a fibrocartilagenous rim attached around the glenoid that helps deepen the glenoid fossa by 50%, providing increased stability of the GH joint. of the scapula.. The glenohumeral joint is a ball and socket joint that includes a complex, dynamic, articulation between the glenoid of the scapula and the proximal humerus. Glenoid The glenoid fossa of the scapula or the glenoid cavity is a part of the shoulder.It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula.It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.. The glenoid fossa can be fractured when a high-velocity blunt force causes the humeral head to impact the glenoid cavity. The glenoid labrum is a wedge-shaped structure that borders the glenoid cavity and appears to provide inherent stability to the glenohumeral joint, thus restricting anterior and posterior excursion of the humerus (see Fig. Joints:The major joint of the shoulder is glenohumeral joint which consists of the ball shaped head of humerus and the socket shaped glenoid fossa of scapula. It is shallow and a site of attachment of glenoid labrum (glenoid ligament), which forms fibrocartilaginous rim around the glenoid cavity. The glenoid cavity forms joint with the head of humerous and impart flexibility to pectoral girdle. We carried out a preoperative MRI to eliminate the possibility of a rotator cuff tear being present. The glenoid labrum (glenoid ligament) is a fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade.The shoulder joint is considered a ball and socket joint. These fractures are typically transverse and occur along the direction of the impact of force. It is a small depression present at the lateral part of the scapula bone or shoulder blade of the pectoral girdle. Ligaments of the Shoulder Ligaments are thick strands of fibers that connect one bone to another. It is shallow and a site of attachment of glenoid labrum (glenoid ligament), which forms fibrocartilaginous rim around the glenoid cavity. The glenoid labrum, a fibrocartilaginous ring, attaches to the outer room of the glenoid fossa and provides additional depth and stability.

The scapula has four bony processes - acromion, spine, coracoid and glenoid cavity. For instance, the glenoid labrum (discussed above) is made up of fibrocartilage which makes it strong and rubbery and able to perform its function of improving shoulder stability. Overhanging the glenoid cavity is a beaklike projection, the coracoid process, which completes the shoulder socket. Question Bank Solutions 14650. Functional results 2 … The meaning of GLENOID CAVITY is the shallow cavity of the upper part of the scapula by which the humerus articulates with the shoulder girdle.

The glenohumeral joint is a ball and socket joint that includes a complex, dynamic, articulation between the glenoid of the scapula and the proximal humerus. Abnormal glenoid version positions the glenoid fossa in an abnormal relationship to the forces generated by the scapulohumeral muscles. The glenoid cavity, also known as the glenoid fossa of the scapula, is the depression in the shoulder blade bone, or scapula, in which the ball-shaped top of the upper arm bone, or humerus, is set. The inferior angle is the most inferior portion of the scapula, and is particularly important because it serves as the attachment point for several powerful muscles involved in shoulder and upper limb movements. The scapula itself is mobile (its orientation shifts on your back with movement), and normal scapular motion is important for normal shoulder function. ‘This joint is formed where your upper arm bone meets the glenoid cavity, which is part of your shoulder blade (scapula).’. glenoid labrum : the cavity has a fibrocartilaginous structure on its margin called the glenoid labrum which is continuous superiorly with the tendon of the long head of biceps brachii. 4.3), which is pear-shaped, concave fossa that narrows superiorly at the anterior glenoid notch, with the inferior 2/3 of the glenoid approximating a circle [7–10]. Hence glenoid cavity is associated with scapula and humerus. Specifically, it is the head of the humerus that contacts the glenoid cavity (or fossa) of the scapula. It is shallow and a site of attachment of glenoid labrum (glenoid ligament), which forms fibrocartilaginous rim around the glenoid cavity. But this shoulder socket is shallow, leaving the joint relatively unstable. The mechanism of an anterior glenohumeral dislocation is abduction, external rotation, and extension that forces … ...
