Question | Answer |
---|---|
the recommended SID for the bilateral Pearson method of the a-c articulation is: | 72" |
the clavicle articulates with: | sternum |
the coracoid process is located on the posterior scapula. | False |
the scapula notch is located __________ to the scapula spine | superior |
whole performing the PA projection of the clavicle, the CR is ___________ to the film | perpendicular |
central ray for the AP projection of the scapula is | 2" inferior to the coracoid process |
which basic projection of the shoulder requires that the humeral condyles be parallel to the cassette? | external |
the AP projection of the a-c joints is used to demonstrate: | separation of the a-c joints |
if the patients condition permits, which joint should be demonstrated with the patient in an upright position? | acromioclavicular |
while performing an AP projection of the a-c articulation (Bilateral Pearson Method) this position is done erect because: | the a-c joint tends to reduce itself standing up |
which two borders of the scapula unite to form the inferior angle? | medial and lateral |
what type of joint is a scapulohumeral? | ball and socket |
how much should the elbow be flexed for the lateral projection of the elbow? | 90 degrees |
on which border is the scapula notch located? | superior |
for the lateral projection of the scapula, the CR enters the __________ border | medial |
the internal oblique elbow demonstrates the: | coronoid process |
which breathing technique should be used to best improve the image contrast and reduce the necessary exposure in the transthoracic lateral projection of the humerus | suspended full inspiration |
the lateral oblique elbow demonstrates the: | radial head |
which two borders of the scapula unite to form the inferior angle | medial and lateral |
the scapula is what classification of bone? | flat |
when performing a lateral projection of the scapula with the patient positioned RPO or LPO approximately how much body rotation is necessary for the average patient | 45-60 degrees |
how many degrees and in which direction should the CR be directed for the PA axial projection of the clavicle? | 20 degrees caudad |
which of the following puts the humerus in a true lateral position? | internal rotation |
which border of the scapula extends from the superior angle to the inferior angle | medial |
the acromion process is located on which of the following bones | scapula |

in an AP radiograph of the elbow, the humeral epicondyles are:: | parallel with the film |
what position would be used if there was an obvious fracture of the upper humerus | transthoracic lateral |
the AR projection of the shoulder in internal rotation will demonstrate a profile view of: | lesser tuberosity |
what are the views for a routine shoulder | AP and external |
the AP projection of the shoulder which will demonstrate the shoulder in true anatomic position: | ap-external rotation |
how must the patient's arm be positioned for a good AP projection of the humerus | abducted |
what is the name of the process that extends anteriorly from the scapula | coracoid process |
where is the anatomical neck of the humerus in relation to the surgical neck | inferior |
what type of joints is the shoulder joint | ball and socket |
what type of joint classification is the shoulder joint | diathrodial |
how many articulations does the humerus have | 3 |
what will best demonstrate the greater tuberosity of the humerus | external rotation |
where should the central ray enter for an ap projection of the shoulder | 1" inferior to the coracoid process |
