As the life expectancy of patients with musculoskeletal tumors improves, long-term studies endoprosthetic reconstructions are necessary to establish realistic expectations for implants and compare them other reconstruction approaches.(1) What is survival cemented bipolar proximal femoral replacements? (2) How does prosthesis patient among Stage I, II, III disease? (3) Do modular outperform custom-built prostheses? (4) some replacements require conversion THA?We retrospectively reviewed all 86 used tumor from 1982 2008. Primary diagnoses were 43 high-grade (IIA/IIB), 20 low-grade (IA/IB or benign), 23 metastatic disease. We survival, complication rates, functional outcomes, rates THA.Five (5.8%) required revision component. Five-, 10-and 20-year implant survivorships 93%, 84%, 56%, respectively. All disease survived; 5-year rate was 16%; 5-, 10-, IIA/IIB 54%, 50%, 44%, Five underwent THA groin pain.Cemented after resection proved a durable technique. The outlived localized while their implants. prostheses comparable that older, one-piece custom designs.
