Follow-up Studies

Painful or failed shoulder 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.
  • Intraarticular or adjacent soft-tissue abnormalities that may require advance imaging for optimal evaluation.

Painful or failed arthroplasties may be due to a variety of problems, including:

  • Instability
  • Polyethylene problems
  • Osteolysis
  • Loosening
  • Infection
  • Fractures
  • Heterotopic ossification
