Chapter 4
What are some wrist movements?
Ulnar deviation and radial deviation
What anatomy should be demonstrated for AP (0 degree) Clavicle
Entire clavicle visualized, including both AC and sternoclavicular joints and acromion.
what are the two arches of the foot?
transverse arch and longitudinal arch
How much do you rotate the leg for AP femur?
rotate the leg 15-20
why do we rotate the Pt's leg 5 degrees internally?
to make sure that the patient is in a true AP position.
what is the part positioning for fingers
• Pronate hand with fingers extended
• Center and align long axis of affected finger with long axis of IR
• Separate adjoining fingers from affected finger
Which respiration is the exposure taken on?
Suspend respiration during exposure.
Which does the navicular articulate with?
Talus, Cuboid, and three cuneiforms
what are some things to look for in an a diagnostic AP femur image?
proximal and distal femur
hip joint and acetabulum.
what are some things to look out for that would let you know your patient is rotated for hip& pelvic exams?
look for elongation and foreshortening of the iliac wings and closing of the obturator foramen.
The joint between the first metacarpal and the proximal phalanx of the thumb is
first metacarpophalangeal (MCP) joint.
Which method is used for shoulder dislocation?
PA oblique (scapular Y), transthoracic lateral, or Garth method
What is the evaluation criteria for toes?
-make sure there is no overlap of anatomy
-include 1/2 of metatarsal
- make sure you have IP and MTP joints
- show some digits of each side of the toe
A patient needs a femur exam after hip surgery. What do you need to make sure you show in your images?
the entire prosthesis in its entirety
what happens if you have external leg rotation in an AP pelvis?
femoral necks decline posteriorly and show foreshortening on a AP pelvis
what is the general positioning rule?
Always place the long axis of part being imaged parallel to long axis of IR
what anatomy should be demonstrated for a shoulder x-ray?
for Ap; lesser tubercle pointing medially
Grashey: open glenohumeral joint, greater tubercle
y view: good visualization of the scapula Y
which knee projection require an angle and how much do you angle it?
Lateral knee
angle 5-7 degrees
What should you see in an AP mid and Distal image?
knee joint
male:-overall shape is bulkier, deeper, narrower
female: -overall shape is smaller, shallower, wider
What are the most distal bones in the hand?
The phalanges, which constitute the digits (fingers and thumb) then metacarpals and then carpals
what should you do if you suspect a dislocation or fracture when taking an exam?
DO NOT ATTEMPT!
what are some special knee projections?
sunrise
tunnel
standing ( bilateral)
What is the patient positioning for AP pelvis?
The PT should be supine. can be done on table bucky or wall bucky.
if the AP hip is in a true AP we will see:
-femoral neck without foreshortening
-greater trochanter shown laterally
-lesser trochanter shown superimposed by the femoral neck
-femoral head and acetabulum are in center of field
