Follow-up Studies

Painful or failed hip arthroplasties are evaluated with serial conventional radiographs. Most of these cases will show radiographic abnormalities. Exceptions include:

  • Acutely infected arthroplasties where the diagnosis has been made very early by clinical exam and arthrocentesis, before radiographic abnormalities have developed.
  • Subtle alignment/positioning abnormalities, which are better demonstrated on CT (cup anteversion)

Painful or failed arthroplasties may be due to a variety problems. These include:
