title: [Metastasis on previous hip arthroplasty: three cases].
abstract: Three cases of metastasis on a previous total hip arthroplasty are reported. The hips had been operated a few years earlier for osteoarthritis. The patients then developed a carcinoma (kidney, prostate, breast) which disseminated producing bony metastases around the prosthesis which caused loosening. All three patients underwent a revision procedure for prosthesis replacement with a metaphysodyaphyseal implant. Carcinological resection was performed in one patient because the metastasis appeared to be unique. At last follow-up two years later, this patient was doing well.
