AP humerus projection
include both shoulder and elbow joints, CR to mid humerus
evaluation criteria AP humerus
entire humerus demonstrated, greater tubercle in profile, medial and lateral epicondyle
in profile
lateromedial and mediolateral humerus projections
epicondyles perpendicular to IR, CR to mid humerus
evaluate criteria for lateromedial/mediolateral humerus
entire humerus demonstrated, lesser tubercle in profile, epicondyles superimposed
AP shoulder (external rotation)
epicondyle parallel, CR 1 inch inferior to coracoid process
evaluation criteria for AP shoulder external rotation
greater tubercle profiled laterally, scapulohumeral joint centered, proximal humerus,
upper scapula, and clavicle visulaized
, AP shoulder internal rotation
epicondyles perpendicular, CR 1 inch inferior to coracoid process
evaluation criteria AP shoulder internal rotation
lesser tubercle profiled medially, scapulohumeral joint centered, proximal humerus,
upper scapula and clavicle visualized
shoulder non trauma specialized projections
