【 摘 要 】

We present a case of an 85-year-old woman with extensive metallosis of the left hip joint secondary to prosthetic polyethelene liner dislocation and wear. Radiographs demonstrated amorphous cloudy radiodensities surrounding the prosthesis, a feature we have called the “cloud sign.�? The presence of amorphous cloudy radiodensities as a radiographic sign of metallosis has not been previously described to our knowledge.
