[X-ray features of the long-term follow-up (l0-12 years) of the Charnley hip prosthesis fixed with acrylic cement].

A long term follow-up (10 divided by 12 years) of Charnley total hip arthroplasties fixed with radiopaque acrylic cement is reported. Clinical results and X-rays features have been correlated and discussed with reference to the bone reaction and to the diagnostic possibilities of standard radiographs. A radiographic diagnosis of loosening preceding relevant clinical symptom may allow revision arthroplasty before anatomical situation becomes too deteriorated.
