Q

For the frontal view of the forearm the hand and wrist should be ______.

A

Supine

20
Q

For a frontal view of a forearm of the proximal radius crosses over the ulna, then what?

A

The bad was improperly pronated.

21
Q

For the humerus the positions of the greater and lesser what should be checked?

A

Tuberosities.

22
Q

In the non rotated frontal view, the greater tuberosity will what?

A

Greater tuberosity will be placed in profile laterally to the anatomical neck.

23
Q

Non rotated frontal view of humerus there will be a distinct internal what?

A

Curvature only on the medial surface of the neck as it “turns” toward the scapula. Figure 135

24
Q

Combining these criteria with the appearance appearance of the elbow, one can what?

A

Make a good judgment of the presence and degree of rotation.

25
Q

Flexion of the elbow joint will do what??

A

Close the joint space between the radius and the humerus off, with the head of the radius superimposing the capitellum of the humerus. Figure 136

26
Q

True lateral views of the elbow, forearm or humerus are all characterized by direct superimposition of what?

A

The two condyles of the humerus as in Figure 137.

27
Q

The line diagram in Figure 138 shows what?

A

Expected appearance of these 2 condyles when rotation or tilt are present.

28
Q

Tilt or improper abduction of the humerus occurs when what?

A

When the patient’s shoulder is not lowered to the level film.

29
Q

What is necessary for all lateral views of the forearm, elbow, and humerus?

A

Shoulder needs to be lowered to the level of the film.

30
Q

When the lateral view of the humerus is improperly rotated what happens?

A

Neither tuberosity will appear distinctly in profile, and on the distal end of the condyles will shift off of each other side-to-side as diagrammed in Figure 138 and demonstrated in 140

31
Q

Lateral view of forearm the wrist must??

A

Be in true lateral.

32
Q

Lateral view of the humerus, how will the tuberosities be placed?

A

Lesser tuberosity will be placed in profile on the medial surface of the humeral neck and the general broadening of the neck area will appear symmetrical with the head head centered upon it like ice cream on a cone. 141

33
Q

Lateral elbow flexed?

A

90 degrees

34
Q

What is the common problem with lateral projections of the humerus, elbow and forearm?

A

Tilt of the humerus

35
Q

The common problem is detected by what??

A

By a vertical, superior to inferior shifting of the numeral condyles. 138 139

36
Q

What is tilt usually due to?

A

Insufficient abduction of the humerus caused by not lowering the patient’s shoulder to the level of the film.

37
Q

How do you bring the shoulder down to the level of the table?

A

The patient must frequently bend at the waist in seated position

38
Q

Trans thoracic lateral view when possible the hand should

A

Hand should be supinated as the patient stands against the film. Not in neutral

39
Q

With the hand in near or full supination, the humerus condyles can be placed how??

A

In true lateral position against film.

40
Q

Transthoracic lateral view not

A

Oblique!

41
Q

With the humerus in true lateral position, the lesser tuberositity will be what?

A

Will be in profile anteriorly, and the neck will show a symmetrical broadening with the head in the middle.

42
Q

Oblique views

With proper 45 degree rotation, the internal oblique of the elbow places what where?

A

The coronoid process of the ulna in profile, with nearly all of the radial head superimposed over the ulna 140

43
Q

Proper rotation on the external oblique opens what?

A

Opens the proximal radioulnar joint with no superimposition of the radial head and ulna

44
Q

In rotated frontalviews the distal phalanx of each finger does what?

A

Appears symmetrical with equal concavity on either side.

45
Q

In true lateral views, the anterior surface of each phalanx will appear as what

A

appear more concave than the posterior side.

46
Q

Rotattaion is rarel a prolem on frontal views of the scapula and clavicle

A

With rotation of the body away fro the affected sidewide with slef everythings else

47
Q

The capular Y position may be critiqued identically to what?

A

The lateral scapula, with the exception that the humerus wll superimpose rark
