Question 1: What are the stress views of the ankle important
Answer:
shows lack of support, from fractures or tears of ligaments
Question 2: Positioning for the AP with medial rotation
Answer:
15-20 degrees medial rotation, centered to ankle. (demonstrates ankle mortise)
Question 3: What does a true lateral of the ankle require?
Answer:
The lateral malleolus to be about 1 cm posterior to the medial malleolus.Question 4: T/F The entire mortise joint is open on an AP oblique ankle with medial rotation (mortise).
Answer:
True
Question 5: What are the two joints are on the tibia
Answer:
proximal and distal tibiofibular joints
Question 6: Before doing a stress view of the ankle what should be ruled out
Answer:
make sure there is no fracture
Question 7: Boom
Answer:
Shockalocka!
Question 8: Positioning for the AP ankle
Answer:
Center to ankle joint, foot dorsiflexed.
Question 9: Identify rotation for the Lateral TIB/FIB
Answer:
Rotation indicated by condyles of femur and ankle joint. Condyles should be superimposed and the proximal head of FIB superimposed by TIB, distal FIB superimposed over posterior half of TIB.
Question 10: A 15deg internal rotated AP oblique projection is called the
Answer:
mortise projection
Question 11: On a true AP of the ankle what is not demonstrated
Answer:
entire three part joint space of the ankle mortise
Question 12: What do you look for on inversion/eversion ankle projections?
Answer:
ligaent attachments
Question 13: T/F An AP tib/fib is done bucky.
Answer:
False. AP tib/fib is done table top Question 14: The proximal tibiofibular joint is classified as what type of joint?
Answer:
Synovial joint and is diarthrodial (freely moveable) and is plane (gliding) type
Question 15: What is demostrated on a AP oblique ankle with 45 degree rotation?
Answer:
The distal tibiofibular joint is open and is in profile.
Question 16: Identify rotation for AP TIB/FIB
Answer:
evaluate relationship of the fibula to tibia. Lat. Rot. - fib shifts toward or under tib, obscuring medial mortise. Med. Rot - head of fib draws from beneath tib.
Question 17: What needs to be visualized on a lateral ankle?
Answer:
The entire talus and calcaneus, lateral malleolus superimposed over posterior half of tibia and talar domes are superimposed Question 18: What is the (rarely used) AP oblique with 45degree medial rotation for?
Answer:
to show tib/fib joint space.
Question 19: The ankle is what type of joint with what type of movement
Answer:
synovial joint, sellar or saddle type and movement is flexion and extension Question 20: What is the difference between the AP mortise and AP oblique ankle projections for positioning
Answer:
internal rotation for mortise is 15-20deg and the ankle is internal rotation of 45deg
Question 21: T/F The intermalleolar line is perpendicular to the IR on a Mortise projection.
Answer:
False. The intermalleolar line is parallel to the IR.
Question 22: The ankle joint is formed by what three bones
Answer:
tibia, fibula, talus
Question 23: What does the mortise joint do for the body
Answer:
helps stabilize weight
Question 24: Identify rotation on Lateral ankle
Answer:
talar domes should be superimposed, lateral malleolus superimposed over posterior half of tibia.
Question 25: Name the 3 Ankle positions (routine)
Answer:
AP, AP oblique with medial rotation, Lateral
Question 26: How do you accurately position for the AP w/ medial rotation?
Answer:
rotate medially until the malleoli are parallel (equidistant) to the IR. Rotate the whole leg NOT just the ankle or foot.
Question 27: You are _____?
Answer:
ON FIRE! Someone call 9-1-1!
Question 28: Which malleolus is longer and is an extension of the fibula
Answer:
lateral malleolus
