title: Total hip replacement after tumor resection--30 years experience.
abstract: The authors report their experience with 161 cemented total hip replacements after tumor resections around the hip implanted between 1971 and 2001 in patients from aged 10 to 79 years. At first, the long stem Protek module was used and since 1980 the Czech made long stem Poldi endoprosthesis has been implanted. A cemented UHMW polyethylene cup has been used with both stems. 66 THR were implanted for primary tumors from which 47 were malignant. 3 Protek and 2 Poldi stems fractured. Early dislocation was common with standard cups; therefore the authors recommend anti-luxation cups with higher rims in all surgeries to enable early ambulation. They also observed better long-term results with the cup slightly in varus. Multiple reimplantations are to be expected when THR is implanted before skeletal maturation, but they are not a problem. The Poldi model is an excellent cost effective solution, especially for secondary malignant tumors around the hip. In the sixties hemiarthroplasty was usually the only chance for a good functional salvage after tumor resections of the proximal femur. Since the seventies special long stems have been developed. Continuous follow up of these surviving patients is important for further development of this special field of endoprosthetics.
