    • midline at the caudal portion of the ischium
    • wings of the ilium - distal patella
  17. Lateral view of the pelvis
    Measure:
    Central ray:
    Borders:
    • at the trochanter or thicket part
    • greater trochanter of the femur
    • slightly cranial to the wing of the ilium- one third of the femur

    affected leg down, abduct and pull unaffected limb laterally.
  21. Describe hindeg positioning for the CrCd view of the femur
    rotate both femurs inward so that the patellae lie over the patellar grooves.
  22. Where do you measure for a CrCd view of the femur?
    Midshaft of the femur
  23. What are the routine views of the stifle?
    • Lateral
