Glenoid cavity of scapula

The bony landmark at the lateral angle of the scapula is the spine. Variations of morphology of the glenoid cavity have been previously reported.

Tibia humerus radius ulna.

Glenoid cavity of scapula. The Glenoid Cavity In Scapula Anatomy. In this image you will find scapula anterior view superior border superior border scapular notch coronoid process infraglenoid tubercle subscapular fossa lateral border an inferior angle in it. You may also find scapula posterior view lateral angle acromion superior border supraspinous fossa a.

The glenoid cavity is part of the shoulder joint. 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 shoulder has three joints.

Size and shape of the glenoid cavity GC of the scapula is directly related to the dislocation of shoulder joint and may affect the results of total shoulder. The glenoid cavity of the scapula often known as the glenoid fossa is a component of the shoulder. On the lateral angle of the scapula there is a shallow pyriform articular surface.

At the sternoclavicular joint it articulates with the manubrium of the sternum breastbone at its rounded medial end sternal end. The cuplike articular surface of the scapula is termed the glenoid or glenoid cavity. The craniomedial margin of the glenoid contains a normal defect.

There is a normal bony outcrop just proximal to the cranial glenoid termed the supraglenoid tuberosity the. The glenoid surface of the labrum is continuous with the hyaline cartilage of the glenoid cavity whereas the capsular surface blends with the joint capsule and glenohumeral ligaments. There can be variations in the width or thickness of the glenoid labrum particularly at the different locations of the glenoid as it relates to the glenoid rim.

The glenoid labrum is a fibrocartilaginous rim attached around the margin of the glenoid cavity. The shoulder joint is considered a ball and socket joint. The glenoid labrum helps to deepen the socket.

It is continuous with the tendon of the long head of. Glenoid fossa It is a shallow pyriform cavity located at the lateral angle of the scapula. It articulates with the rounded head of the humerus forming the glenohumeral shoulder joint.

Supraglenoid tubercle It is a small rough projection located immediately above the glenoid fossa near the base of the coracoid process. The articulation of the scapula and the humerus occurs at the glenoid cavity. This creates a ball-in-socket joint which results in the shoulder the most flexible joint found in the human body.

The glenoid fossa is involved in approximately 10 of all scapular fractures. Glenoid fossa incongruity is surprisingly well tolerated. Surgery is recommended when 20 or more of the anterior glenoid fossa is involved.

Glenoid rim fractures often lead to chronic shoulder instability. The large spherical head of the humerus and the small glenoid cavity of the scapula are the articular surfaces of the glenohumeral joint. Each of the surfaces is enveloped by hyaline cartilage.

The convex humeral head articulates with a firm concave surface which is given by the glenoid cavity. The coxal joint is a ball-and-socket joint in which the head of the humerus articulates with the glenoid cavity of the scapula. Asked Sep 28 2016 in Anatomy Physiology by SqRspC.

The head of the humerus and the glenoid cavity form a ball-and-socket joint. Variations of morphology of the glenoid cavity have been previously reported. These influence the surgical reconstruction or arthroplasty of the shoulder.

This study aims to study the variation of the shape of suprascapular notch shape of glenoid cavity dimensions of both the scapular and the glenoid cavity and predict the glenoid dimensions from the scapular dimension parameters. In scapulapresents a shallow cavity the glenoid cavity which articulates with the head of the bone of the upper arm the humerus to form the shoulder joint. Overhanging the glenoid cavity is a beaklike projection the coracoid process which completes the shoulder socket.

To the margins of the scapula are attached Read More. The coxal joint is a ball-and-socket joint in which the head of the humerus articulates with the glenoid cavity of the scapula. The glenoid or glenoid cavity or fossa is the shallow depression of the scapula found on the lateral angle.

Gross anatomy Attachments glenoid labrum. The cavity has a fibrocartilaginous structure on its margin called the glenoid labrum which. On the lateral angle of the scapula is a shallow pyriform articu-lar surface- the glenoid cavity also known as glenoid fossa of the scapula.

The vertical diameter of the glenoid cavity is the longest and it. The bony landmark at the lateral angle of the scapula is the spine. The coronoid fossa is found on which of the bones listed below.

Tibia humerus radius ulna. Glenoid neck fractures may involve both translational and angular deformity and can also lead to chronic pain and weakness due to the alteration of glenohumeral biomechanics. The most frequently used classification for fractures of the glenoid cavity is that proposed by Ideberg 11 and further modified by Goss 12.

Citation needed The glenoid cavity is made deeper by the addition of the fibrocartilaginous ring of the glenoid labrum. The capsule is a soft tissue envelope that encircles the glenohumeral joint and attaches to the scapula humerus and head of the biceps. Glenoid fossa - the concavity in the head of the scapula that receives the head of the humerus to form the shoulder joint.

Scapula shoulder blade shoulder bone - either of two flat triangular bones one on each side of the shoulder in human beings. The glenohumeral joint is structurally a ball-and-socket joint and functionally is considered a diarthrodial multiaxial joint. The glenohumeral articulation involves the humeral head with the glenoid cavity of the scapula and it represents the major articulation of the shoulder girdle.
