What process is best seen using a perpendicular CR with the elbow in acute
flexion and with the posterior aspect of the humerus adjacent to the image
receptor? - CorreCt Answers -Olecranon
A lateral projection of the hand in extension is often recommended to
evaluate - CorreCt Answers -1. a foreign body.
2. soft tissue.
The lateral hand in extension, - CorreCt Answers -with appropriate
technique adjustment, is recommended to evaluate foreign body location in
soft tissue. A small lead marker is frequently taped to the spot thought to be
the point of entry. The physician then uses this external marker and the
radiograph to determine the exact foreign body location. Extension of the
hand in the presence of a fracture would cause additional and unnecessary
pain, and possibly additional injury.
following structures into order (A-D) from medial to lateral. - CorreCt
Answers -(A) Vertebral border
(B) Scapular notch
(C) Coracoid process
(D) Acromion process
The scapula - CorreCt Answers -is a flat bone, shaped like an inverted
triangle, with a costal surface that lies against the upper posterior rib cage.
The scapula has a superior border, a medial (or vertebral) border, a lateral
,(or axillary) border, and an inferior angle, or apex. Its superior border
presents a scapular notch projecting anteriorly just medial to the palpable
coracoid process. The scapular spine divides the posterior surface into a
supraspinatus fossa and infraspinatus fossa; the acromion process is the
lateral extension of the scapular spine. The glenoid fossa is on the lateral
aspect of the scapula and, with its articulation with the humeral head,
forms the (ball and socket) shoulder joint.
lateral oblique (external rotation) projection of the elbow - CorreCt
Answers -removes the proximal radius from superimposition with the ulna
and demonstrates its articulation with the ulna at the radial notch, the
proximal radioulnar articulation.
An AP projection of the elbow would demonstrate - CorreCt Answers -
partial overlap of the proximal radius and ulna
A medial oblique of the elbow would demonstrate - CorreCt Answers -
complete overlap of the proximal radius and ulna; this position is used to
demonstrate the coronoid process in profile and the olecranon process
within the olecranon fossa
Which of the following projection(s) require(s) that the shoulder be placed
in internal rotation? - CorreCt Answers -Lateral humerus
When the arm is placed in the AP position - CorreCt Answers -the
epicondyles are parallel to the plane of the cassette and the shoulder is
placed in external rotation. In this position, an AP projection of the
humerus, elbow, and forearm can be obtained; it places the greater tubercle
of the humerus in profile.
, For the lateral projection of the humerus - CorreCt Answers -the arm is
internally rotated, elbow somewhat flexed, with the back of the hand
against the thigh and the epicondyles superimposed and perpendicular to
the IR. The lateral projections of the humerus, elbow, and forearm all
require that the epicondyles be perpendicular to the plane of the cassette.
The fifth metacarpal is located on which aspect of the hand? - CorreCt
Answers -Medial
With the arm in the anatomic position, - CorreCt Answers -the fifth
metacarpal and the ulna lie medially
What portion of the humerus articulates with the ulna to help form the
elbow joint? - CorreCt Answers -Trochlea
The distal humerus articulates with - CorreCt Answers -the proximal radius
and ulna to form the elbow joint. Specifically, the semilunar/trochlear
notch of the proximal ulna articulates with the trochlea of the distal medial
humerus.
The capitulum is lateral to the trochlea and articulates with - CorreCt
Answers -the radial head
All the following can be associated with the distal radius - CorreCt Answers
-a. styloid process.
B. ulnar notch.
C. radioulnar joint.
