Exam 1 2nd year fall semester procedures
exam: patella, IC fossa, Femur,
Acetabulum, hip, pelvis, ribs, Sc joints
ACTUAL QUESTIONS AND CORRECT
ANSWERS
what is the central ray orientation for the IC fossa PA axial holmblad method? - CORRECT
ANSWERS✅✅perpendicular to the lower leg, entering the superior aspect of the popliteal
fossa and exiting at the level of the patellar apex, for all three positions
what are the three methods used to show the IC fossa? - CORRECT
ANSWERS✅✅holmblad
beclere
camp coventry
what is the degree of angulation for the tib/fib from the plane of the IR for the camp coventry
method? - CORRECT ANSWERS✅✅40-50 degrees from the plane of the IR
what is the central ray orientation for the camp coventry method? - CORRECT
ANSWERS✅✅CR angled (towards heel) 40 degrees when the knee is angled 40 degrees
and 50 degrees when the knee is angled 50 degrees
with the camp coventry method is the IC fossa foreshortned or elongated? - CORRECT
ANSWERS✅✅elongated
for the beclere method you flex the knee enough to place the long axis of the femur at an
angle of, what degree, to the long axis of the tibia? - CORRECT ANSWERS✅✅60 degrees
what is the central ray orientation for the beclere method? - CORRECT
ANSWERS✅✅perpendicular to the long axis of the lower leg, entering the knee joint 1/2
inch below the patellar apex
, the beclere method to show the IC fossa has more ------------- and less ---------- of the
intercondylar fossa - CORRECT ANSWERS✅✅magnification
elongation
how much and in which direction should the heel be rotated for the PA patella? - CORRECT
ANSWERS✅✅5-10 degrees laterally
what is the central ray orientation for the PA patella? - CORRECT
ANSWERS✅✅perpendicular to the midpopliteal area, exiting the patella
why do we do a PA patella instead instead of the AP patella? - CORRECT
ANSWERS✅✅the PA projection of the patella provides improves spatial resolution over the
AP projection because of a closer OID
for the tangential, merchant method to show the patella and patellofemoral joint what is the
degree of knee flexion? - CORRECT ANSWERS✅✅40 degrees (but could be anywhere
between 30 and 90)
Where should you place the IR for the tangential, merchant method to show the patella and
patellofemoral? - CORRECT ANSWERS✅✅place the IR perpendicular to the central ray
and resting on the patients shins, 1 foot distal to the patella
What is the CR orientation for the tangential, merchant method to show the patella and
patellofemoral? - CORRECT ANSWERS✅✅perpendicular to the IR
with 40 degree knee flexion, angle the CR 30 degrees caudad
entering midway between the patella at the level of the patellofemoral joint
what is the central ray orientation for the settegast method? - CORRECT
ANSWERS✅✅perpendicular to the joint space between the patella and the femoral
condyles when the joint is perpendicular. When the joint is not perp. the degree of CR
angulation depends on the degree of knee flexion, this is typically between 15-20 degrees
what is the purpose of a scout image? - CORRECT ANSWERS✅✅to rule out fractures
