Imaging Features and Clinical Significance of the Acromion Morphological Variations
Journal of Novel Physiotherapies
True anteroposterior views It is necessary to take the true anteroposterior radiograph that the scapular plane should be parallel to the X-ray cassette. Since the scapular plane rest at an angle of approximately 45 degrees to the coronal plane, the patient needs to rotate the body until the scapular plane is parallel to the X-ray cassette ( Figure 1 ). The patient needs the forearm to be at the side of the body without abduction and with the palm facing forewards. On this position, the views
... ition, the views could show clearly the space between the glenoid and the humeral head, the middle part Anteroposterior views If the coronal plane of the thorax parallel to the X-ray cassette, the anteroposterior view of the glenohumeral joint is obtained. In this views, the humeral head to be overlapping with the glenoid, and the outline of the glenoid is oval but not is line, the clavicle is unfolded (Figure 2 ). Abstract The pathogenesis of rotator cuff tears is complex and chaos; however, the rotator cuff tears have been related to the morphology of the acromion. We named those variations of the acromial morphological as "Congenital and Osteal Etiological Factors", which include the shape, lateral extension, the angle between the undersurface of the acromion and the glenoid and the distance from acromion to humeral head. of clavicle is overlaped; the fringe of the glenoid is in a line       .
