Humerus and Transthoracic WS Flashcards
When performing a transthoracic lateral for humerus on a patient who is unable to adequately drop their arm, you should –1–.
Angle CR 10-15 degrees cephalic.
The CR should be directed to the –1– for a routine AP humerus.
Perpendicular to mid-portion of the humerus.
Proper respiration for the AP and lateral humerus should be –1–.
Suspend respirations
When the arm in in flexion, the –1– process is within the –2– fossa on the anterior surface,
- Coronoid
2. Coronoid
The –1– tubercle will be demonstrated in profile and on the –2– surface when the humerus is placed in the AP position.
- Greater
2. Lateral
An imaginary line drawn through the humeral epicondyles should be –1– to the IR if a proper lateral position is achieved.
Perpendicular
What is the advantage to performing the humerus study in the upright position?
They are often less painful for the patient and decrease chance of further injury.
The CR should be directed to vertebral level –1– for the PA chest radiograph.
T7
The correct degree of obliquity for a wrist study is –1– degrees.
45
In order to properly perform an AP thumb radiograph, the hand must be placed in –1–.
Extreme internal rotation
What should be included on a humerus radiograph to ensure that it is seen in its entirety?
Structures of the shoulder girdle and the elbow joint.
According to Merrills, what surface of the hand should be placed along the patient’s side in order to properly perform a lateral humerus on the recumbent patient?
Posterior surface
When performing exams using CR, it is important that the structure be in the center of the IR and is placed as straight on the IR as possible. What is another extremely important act to perform in order to increase the picture quality if the image?
- Collimation (most important)
2. Set/use proper technique
Another name for the intertubercular groove is the –1–.
Bicipital groove
Deep posterior fossa of the humerus.
