Wrist
scaphoid
How many bones are in the hand?
27
For the AP projection of the forearm, the hand is
pronated or supinated, and why?
Supinated; if PA was done, the radius would cross over the ulna. Therefore, we do AP to separate the two bones.
How many routine views of the elbow are there?
What are they called?
AP, Lateral, Internal/External Oblique
What is the breathing instructions for humerus
suspended respiration
The first bone located on the proximal row and lateral side of the wrist is called the
Scaphoid
How many phalanges are in the hand
14
What two joints must be on a 2v forearm x-ray?
Elbow and wrist
For the AP projection of the elbow, the humeral epicondyles are positioned
Perpendicular, parallel, superimposed, or not seen
parallel to the IR
Which tubercle is seen in the AP view/Lateral View
Greater
Lesser
What is the largest carpal bone out of the proximal and distal row
Capitate
What is the CR for a PA hand & oblique PA hand?
What is it for the fan lateral?
3rd MCP
2nd MCP
How much is the elbow flexed for a lateral forearm
90 degrees
How much should the elbow be rotated for an internal oblique to demonstrate the appropriate structures?
45 degrees
How far above the humeral head should the upper margin of the IR be placed for an AP humerus?
1.2 inches
What is the method called for carpal tunnel view?
Gaynor Hart Method
How many phalanges are in the thumb? What are they called?
2; Distal and Proximal, there is no middle
Which structure is not on the radius?
head, styloid process, tuberosity, lateral epidcondyle
Lateral epicondyle
What anatomy should be projected free of superimposition for an AP oblique projection of the elbow with medial rotation?
Lateral epicondyle, coronoid process, olecranon process, or olecranon fossa
cornoid process
The head of the radius fits into a depression on the lateral aspect of the coronoid process of the ulna. This depression is called the
radial notch
The IR must be elevated how many degrees for the PA axial projection of the wrist (for the scaphoid)? & What is the method called?
20 degrees, Stetcher Method
For a 5th digit finger, where is the CR?
Does the medial or lateral surface touch the IR for the lateral view?
5th PIP
Medial
If a patient is unable to extend the forearm for an AP projection of the elbow, how many projections are necessary to avoid distortion of the joint?
2
What does the lateral, internal, & external elbow show?
Lat- Olecranon & fat pads
Ext- Capitulum and radial h,n,t free from superimposition
Int- Coronoid process & Trochlea
The posterior fat pad lies in the
Olecranon fossa
