humerus Flashcards
Humeral epicondyles parallel with plane of film
HUMERUS AP
Best demonstrate the Greater tubercle in profile
HUMERUS AP
Epicondylar line perpendicular to the film
HUMERUS LATERAL
Best demonstrate the lesser tubercle in profile
HUMERUS LATERAL
A true lateral is confirmed by _____
by the superimposed epicondyles
Instruct the patient to do shallow breathing to blur out ribs and lung structures to better visualize the proximal humerus
HUMERUS/SHOULDER JOINT TRANSTHORACIC LATERAL PROJECTION LAWRENCE METHOD
central ray of HUMERUS/SHOULDER JOINT TRANSTHORACIC LATERAL PROJECTION LAWRENCE METHOD
- Perpendicular to the surgical neck.
- 10°-15° cephalad if the patient cannot elevate the unaffected shoulder.
What is seen in the HUMERUS/SHOULDER JOINT TRANSTHORACIC LATERAL PROJECTION LAWRENCE METHOD
Lateral view of the proximal 2/3 of the humerus
Alternative position taken primarily in cases of trauma to the upper arm or shoulder or when the patient is otherwise unable to rotate or abduct the arm.
HUMERUS/SHOULDER JOINT TRANSTHORACIC LATERAL PROJECTION LAWRENCE METHOD
SHOULDER JOINT AP PROJECTION 3 rotations
neutral rot, internal rot, external rot
EPICONDYLES - Neutral Rotation
45 deg angle to plane of cassette
EPICONDYLES - Internal Rotation
perpendicular to the plane of cassette
EPICONDYLES - External Rotation
parallel to the plane of the cassette
BD - Neutral Rotation
greater tubercle (partially superimposed)
BD - Internal Rotation
lesser tubercle (medially)
BD - External Rotation
greater tubercle (laterally)
CR - Neutral rot
perpendicular to the coracoid process - 1 inch (2.5 cm) inferior to the coracoid process
Oblique view of the proximal humerus
SHOULDER JOINT AP PROJECTION neutral rotation
The true AP projection of the humerus in the anatomic position
SHOULDER JOINT AP PROJECTION external rotation
Lateral view of the humerus
SHOULDER JOINT AP PROJECTION internal rotation
CR of inferosuperior axial projection - lawrence method
Horizontally through the axilla to the acromioclavicular joint
Profile image of site of insertion of the supraspinatus tendon
SHOULDER JOINT AP PROJECTION external rotation
CR if hindi kaya ng patient abduct hand ng 90 sa inferosuperior axial projection - lawrence method
15-30
BD inferosuperior axial projection - lawrence method
Best demonstrate the lesser tubercle in profile directed anteriorly
