4. Part Position for AP Done in the table bucky
Patient in Supine position on table
Align knee mid-line of table
Rotate foot internally 3 -5 degrees for true AP

5. CR perpendicular Tibial platea
40 SID
½” Distal to apex of patella

6. CR ANGLE DIFFERENCE Measure the distance from ASIS to table
19-24 Average Patient perpendicular
25-up Above average Patient 5 degrees cephalad
Below 19 Below Average 5 degrees caudad.

7. Our CR Angle For our comp we will shoot straight in
So our distance will be 40
DON’T FORGET TO LINE BUCKY

Measures 10

24. Part position for AP Patient Supine on table Place shield over lap
leg fully extended
place leg in true AP position for knee and ankle
Femoral condyles parallel to IR
foot flexed to 90 degree (TOES up)
include both joints (knee & ankle) IR.

26. Central Ray 40 SID perpendicular to mid-leg
Collimate to skin borders on lateral and medial sides.
Leave collimation open from top to bottom
** can go up to 44 or 48 SID to include more of part**

27. Seen on Radiograph The entire tibia and fibula
both ankle and knee joint
the condyles of tibia and femur in profile
the intercondylar eminence centered in the intercondylar fossa
some imposition of distal and proximal tib/fib

28. Lateral Tib/Fib

29. Part position for lateral
Patient on side with injured side down
flex knee about 45 degree to ensure true lateral
plane of patella should be perpendicular to IR
opposite leg behind injured one
both joints included on IR

30. 40 SID

31. Central Ray perpendicular to mid-leg
collimation to skin borders on sides
open fully top to bottom

32. Seen on Radiograph Entire tib/fib both joints
tibial tuberosity in profile
fibula head imposed by tibia
distal fibula imposed on posterior portion of tibia
femoral condyles superimposed.

33. !!!Important Note!!!! If you can not fit entire leg on on film...
You must include the joint nearest the injury on the film and take a separate picture of the other joint.
