Published reports dealing with tumor prosthesis have yet to establish a clear advantage of using either cemented or cementless implants. We examined the outcome and complications with modular cemented implants in 135 patients identified from our database to strengthen the argument for routine use of cemented constructs. The minimum followup was 1.4 months (mean, 57 months; median, 47 months; range, 1.4-157 months). The majority of patients (104) had sarcoma. The complications included: 11 infections, three of which underwent amputation and one a stem revision; eight local recurrences, five of which underwent amputation; three hip dislocations; and three incidents of shoulder instability. One periprosthetic femur fracture was stabilized operatively. There was no aseptic loosening or stem fracture. The 5-year survival rates for distal femoral and proximal humeral replacements were 84% and 70%; the 10-year survival rates were 79% and 59%. The 5-year survival rates for proximal femur and proximal tibia replacements were 78 % and 37 %. Average Musculoskeletal Tumor Society 1987 scores and Toronto Extremity Salvage Scores were 21.5 and 73% for proximal femur, 28.1 and 67% for distal femur, and 21 and 78% for proximal humerus. The survival of the endoprostheses related to site of bone resection. Cemented constructs of modern design in the context of tumor surgery provide good short-term results.
