This results in a more AP glenoid view, and although diagnostically relevant to shoulder pathology, it is not an accurate representation of the surrounding structures. The technical factors of this examination are not particularly demanding, and there is not much room for positioning error other than over or under rotation to compensate for the scapular body.Īn open glenohumeral joint is a sign of over rotation toward the affected side. no foreshortening of the scapular body (as per the patient rotation discussed in the positioning).a slight overlap of the humeral head with the glenoid.the entire clavicle is visualized alongside the glenoid cavity and scapula in the AP position.medial to include the sternoclavicular joint.inferior to include one-third of the proximal humerus.2.5 cm inferior to the coracoid process, or 2 cm inferior to the lateral clavicle at the level of the glenohumeral joint.Therefore, the body of the scapula is laying parallel with the image receptor Description Calcific tendonitis is a painful inflammatory condition involving the resorption of calcium hydroxyapatite deposits in or around a tendon. Because bone cells die without a blood supply, AVN can ultimately lead to destruction of the shoulder joint and arthritis. the patient is slightly rotated 5-10° toward the affected side. Avascular necrosis (AVN) of the shoulder is a painful condition that occurs when the blood supply to the head of the humerus is disrupted.affected arm is in a neutral position by the patient side.glenohumeral joint of the affected side is at the center of the image receptor.midcoronal plane of the patient is parallel to the image receptor, in other words, the patient's back is against the image receptor.Additionally, this view is useful in assessing for degenerative diseases which may be seen as calcium deposits in bursal structures, muscles or tendons around the shoulder. This view helps in visualizing potential fractures or dislocations to the proximal humerus and shoulder girdle in a trauma setting.
