Abstract
Aims: The purpose of this study is to evaluate the experience of the Prague tumour centre with total hip replacements after tumour resections. Methods: 180 THR were implanted between 1971 and 2001 in the Prague tumour centre after resections of primary and secondary bone tumours. 158 had special long and 22 standard stems. The patients were followed in a minimum one-year interval both clinically and radiologically until their death or for at least þve years. Clinical and radiological data are evaluated. Results: Among the 158 long stem femoral components there were 63 primary bone tumours (10 Ewing sarcoma, 10 myeloma 9 chondrosarcoma, 7 osteosarcoma, 7 malignant þbrous histiocytoma, 4 malignant lymphoma, 4 giant cell tumours and 15 other benign tumours). Most of the 95 metastatic cases originated in the breast, kidney and lungs. The range of motion was surprisingly good when muscles were reattached around the stem. Luxations occurred until the antiluxating cup was developed. Even if these patients showed a higher risk of infection, reoperation was not a severe problem. Conclusions: THR with a long stem is a good salvage method after primary tumour resection around the hip. It is a method of choice in meta-static patients with or without pathologic fractures especially in solitary bone metastasis. Luxation can be a problem when not using an antiluxa-ting cup as well as replacement in children with unþnished skeletal development. Reattachment of the Ç muscle ring È improves the outcome.
