Question | Answer |
---|---|
evaluation criteria - AP forearm | -wrist and distal humerus included -superimposed radial head, neck and tuberosity over proximal ulna -no elongation or foreshortening of epicondyles -partially open elbow joint -open radioulnar joint |
evaluation criteria - lateral forearm | -wrist and distal humerus included -superimposed distal radius and ulna -radial head superimposed over coranoid -radial tuberosity facing anteriorly -superimposed epicondyles -elbow flexed 90 degrees |
evaluation criteria - AP elbow | -radial head neck and tuberosity slightly superimposed over ulna -elbow joint open and centered -no rotation of epicondyles |
evaluation criteria - lateral elbow | -elbow joint open and centered -elbow flexed 90 degrees -superimposed epicondyles -radial tuberosity facing anterior -radial head slightly superimposing coranoid -olecranon seen in profile |
evaluation criteria - AP oblique elbow (lateral rotation) | -radial head neck and tuberosity free of superimposition -capitulum well demonstrated -open elbow joint |
evaluation criteria - AP oblique elbow (medial rotation) | -coronoid in profile -trochlea well demonstrated -ulna superimposed by radial head and neck -olecranon process seen in olecranon fossa |
