RADIOGRAPHY

Conventional radiographs are initially obtained post operatively, and serve as a baseline study. They are used as reference films for comparison for all future studies.

Sequential radiographs are the most important method of evaluation of the painful total hip replacement

Conventional radiographs are easily obtained and a cost effective imaging modality in the evaluation of patients with hip arthroplasties.

• Standard views
  • AP pelvis
  • Modified frog lateral view

• AP pelvis

  • Obtained on large film (14 x 17)
  • The top of the cassette is placed 2 inches below iliac crest
  • Centered low to include entire femoral component
    

• Frog lateral view

  • Patient positioned 45 degrees laterally rotated towards effected side
  • Tube angled 15 degrees cephalad.

All serial follow-up films are obtained with the same positioning method to facilitate accurate comparison.
