This Exam contains:

-Guarantee passing score -100 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: On the lateral frog-leg hip, where is the lesser trochanter positioned almost everytime?

Answer:

the lesser trochanter should be seen on the posterior surface of the femur.Question 2: If the fibula is used to detect rotation, where is it positioned for the knee to be too far away from the IR?

Answer:

the fibula is anterior and more superimposed by the tibia than normal

Question 3: What is the CR placement for a xtable lateral hip?

Answer:

perpendicular to long axis of the femoral neck

Question 4: What is the interosseous spacing?

Answer:

spacing between the fibula and tibia

Question 5: On a lateral frog leg if the greater trochanter moves too medially what positioning error is present?

Answer:

too much flexion Question 6: How much is the tube angled for hypersthenic patients on the AP knee?

Answer:

• degrees cephalic; when the thighs and buttocks are greater than 24cm

Question 7: T/F: On the lateral knee, the fibular head should be free of superimposition of the tibia.

Answer:

false; if this occurs it means the knee is too close to the IR, and the foot is elevated. There should be slight superimposition on the lateral knee.

Question 8: Which joint space should be open on the AP knee?

Answer:

tibiofemoral

Question 9: What is the CR placement for the AP hip?

Answer:

perpendicular to the femoral neck

Merrill's: 2 1/2" distal to midpoint of ASIS & pubic symphysis

Bontrager: 1-2" distal to mid-femoral neck

Question 10: What positioning error foreshortens the femoral neck on a lateral frog leg?

Answer:

too much abduction

Question 11: How do you check for rotation on the AP tib/fib?

Answer:

*interosseous spacing: more space=medial rotation

less space=lateral rotation *femoral & tibial condyles in profile *intercondylar eminence centered in the intercondylar fossa

Question 12: If you are determining rotation on a lateral knee using the medial or lateral condyle, how is the condyle positioned for the knee to be too far away from IR?

Answer:

the medial condyle is too posterior Question 13: On the lateral frog hip, how much should the affected side knee be flexed from the table?

Answer:

60-70 degrees from the table Question 14: Which joint should be included on the AP distal femur? and how much should be included?

Answer:

knee joint must be included; lower margin of IR should be about 2" below knee Question 15: On a lateral tib/fib, if there is too much superimposition of the tibia over the proximal head of the fibula how is the knee position in respects to the IR?

Answer:

the knee is elevated and too far away from the IR.

Question 16: How should the patella be positioned on the AP knee?

Answer:

completely superimposed on the femur and in the center.

Question 17: How much should the knee be flexed on a lateral femur?

Answer:

45 degrees

Question 18: What makes the femoral neck foreshortened on the AP Hip?

Answer:

*externally rotating the foot *foot being in a natural straight position

Question 19: Which tunnel view has the body positioned PA where the body leans forward 20-30 degrees from vertical?

Answer:

Holmblad Method Question 20: What is the tunnel view that the lower leg is flexed 40 degrees and the CR is perpendicular to the long axis of the lower leg?

Answer:

Camp-coventry Method

Question 21: If the knee is bent more than 30 degrees what happens?

Answer:

over flexion closes the femoropatellar joint space.

Question 22: What is the CR for the merchant bilateral method?

Answer:

30 degrees caudad; midway between patellae

Question 23: What is the CR for the lateral patella?

Answer:

perpendicular to mid patellofemoral joint Question 24: On a distal lateral femur, what if the femoral condyles are not superimposed over each other?

Answer:

this may happen because of beam divergence; this causes the space between the femoral condyles and tibia to be closed as well Question 25: What positioning error foreshortens the femoral shaft on a lateral frog leg?

Answer:

too little abduction

Question 26: where is the CR placement for medial and lateral oblique knee?

Answer:

1/2" distal to apex of patella; midpt of knee
