leg & intercondylar fossa Flashcards
1
Q
- femoral condyles are parallel with the IR and the foot is vertical.
- Flex the ankle until the foot is in the vertical position.
- CR Perpendicular to the center of the leg.
- shows tibia, fibula, and adjacent joints

AP Projection
2
Q
- Turn the patient toward the affected side
- place the patella perpendicular to the IR.
- CR Perpendicular to the midpoint of the leg
- shows tibia, fibula, and adjacent joints
A
LATERAL PROJECTION
Mediolateral
3
Q
- Standing with the knee of interest flexed and resting on a stool at the side of the radiographic table.
- Standing at the side of the radiographic table with the affected knee flexed and placed in contact with the front of the IR.
- Kneeling on the radiographic table, with the affected knee over the IR.
- place the IR against the anterior surface of the patient’s knee, and center the IR to the apex of the patella
- flex knee 70 degrees from full extension (20 degree diff from CR)
- perpendicular to the lower leg, entering the midpoint of the IR
- shows intercondylar fossa of the femur and the medial and lateral intercondylar tubercles of the intercondylar eminence in profile

Q
- prone
- flex knee to either 40 or 50 degree angle, rest foot on support

Q
- supine
- flex affected knee, place the long axis of the femur at an angle of 60 degrees to the long axis of the tibia
- IR under the knee
- CR Perpendicular to the long axis of the tibia, entering the knee joint 1/2 inch below the patellar apex
- shows intercondylar fossa
