Trauma Shoulder Flashcards
(20 cards)
What are the three tion’s to demonstrate the shoulder
Dislocation
Separation
Function
How do we properly give the weights for AC exams
At the same time 5-10 lbs cause less muscles are being contracted
Where is the CR for AC
Level of manubrium notch
What do the letters c, s, and 0 stand for ?
C-with
S, 0 - without
What is the method name for AC joints
Pearson method
Where is the affected arm positioned for an AP projection of the scapula and why ?
Abducted laterally at a 90 degree angle and to get the scapula lateral
What 2 scapula borders are superimposed for the lateral scapula
Medial and lateral borders
What three things can be determined for mid-clavicle
Bisecting AC and SC joints
Bisecting sternal and acroimion extremity
Lateral and medial portion
What positioning modification makes the shoulder a “true” AP and what occurres ?
Slightly rotate pt. To affected side and scapula is getting more parallel
Why is a longer SID used for AC joints
To reduce magnification and to get both AC joints on one film
What is the proper respiration for AP or PA clavicle and why ?
Suspend on expiration to even out densities
What is the proper respiration for a AP axial and why ?
Full inspiration to elevate the clavicles from the apices and angle them
The CR projection for AP axial and lordotic position for clavicle
AP axial - 15-30 degrees cephalad
Lordotic- 0-30 degrees cephalad
For AP scapula where is the IR and CR directed
IR- 2” above shoulder
CR- 2” inferior to Coracoid process
What respirations can be used for AP scapula
Slow breathing to blur out lung and rib markings
Suspend on expiration for more uniform density
What two arm positions are used for the lateral scapula
- ) to demonstrate acromion and coracoid. Flex elbow and place back of hand behind back may also place at pt. Side
- ) dem body. Reaching hand across the opp. Shoulder or extend arm upward and rest forearm on the head
What tells you if the pt is not rolled or rolled to much for the lateral scapula
Rolled too much- narrow portion of lung
Not rolled enough- wider lung field
Why is an AP clavicle more essential than a PA
Less mag and OID
What can you do if pt can’t be placed in upright pos. , a FX, or destructive disease for clavicle
Use supine position to reduce the possibility of fragment displacement or add injury
How do you know if you got the whole scapula on the radiograph ?
Acromion process to inferior angle
