Humerus and Transthorasic Humerus Review Flashcards
The term that is used to describe the arm that is furthest away from the IR is –1–.
a. Remote
Referring to previous question, what should be done with this arm when performing the transthoracic lateral humerus.
c. Elevate it above the head
When performing the AP position/projection of the humerus, the –1– is being demonstrated at the proximal end of the humerus.
c. Greater tubercle on lateral surface
When positioning a lateral humerus, the CR should be directed to the –1–.
c. Humeral shaft
When the humerus is in flexion, the –1– process is in the –2– fossa.
c. 1 Coronoid 2 Coronoid
The –1– of the humerus hinges with the radial head.
d. Capitulum
The humeral head articulates with the –1– of the –2– to form the shoulder joint.
d. 1 Glenoid fossa 2 Scapula
If the patient can’t adequately drop the affected shoulder/humerus down when performing the transthoracic lateral, the CR may be angled –1– degrees –2– in order to separate the shoulders from one another.
c. 1 10-15 2 Cephalic
When performing the routine humerus positions, the respirations should be –1–.
c. Suspended
Explain why the upright humerus may be the method of choice for this exam .
It is less painful for the patient.
What is the method name for the transthoracic lateral humerus.
Lawerence Method
When would you perform the x-table lateral for the distal humerus?
When you can’t fully internally rotate the humerus.
In the AP position/projection of the humerus, a line drawn through the epicondyles should be –1– to the IR if the patient was properly positioned.
Parallel
The IR/ cassette should be placed –1– inches –2– the affected shoulder when performing the transthoracic lateral.
- 1 1/2 inches
2. above
If performing the recumbent lateral humerus , what surface of the hand is placed against or alongside the patient?
Posterior
In order to properly position an AP humerus what action is performed with the hand?
Supination
List the 2 breathing options for a transthoracic lateral humerus and why each is performed.
- Full inspiration to improve the contrast and decrease exposure necessary for penetration. (blacks out lungs)
- If sufficiently immobilized to prevent patient movement, a breathing technique may be used; slow, deep breathing with a minimum exposure time of 3-5 sec (4-5 desirable); give excellent results when a low MA is used. (using motion to blur out ribs, lungs, and adjacent structures to show the proximal humerus)
What is being demonstrated (and on what surface) when performing a lateral humerus? (referring to the proximal end of the humerus)
Lesser tubercle on the medial surface.
What must be on the finished radiograph of a humerus in order to be sure that all anatomy is present?
Structures of the shoulder joint to the complete elbow joint.
When performing any bony extremity on an injured patient who may or may not be able to achieve the required positions, it is important to always get a minimum of 2 views that are –1– degrees different from one another.
90 degrees
The correct centering for an upright abdomen exam is…
2 inches above umbilicus
Name 3 reasons to perform a chest exam in the upright position.
- Diaphragm in its lowest position
- Prevent engorgement of pulmonary vessels
- You see the full/entire lung field
Most bone work tends to be –1– scale and –2– contrast.
- short
2. high
The largest carpal bone is the –1– which is located in the –2– row of carpal bones.
- Capitate, Os Magnum
2. Distal
What could be done to eliminate variations in density on the humerus radiograph if using conventional filming?
Use a filter
What is the structure that is located between the greater and lesser tubercles on the humeral head?
Bicipital groove
When is the transthoracic lateral exam utilized?
When the patient can’t fully internally rotate their arm.
