Abstract
in English, French

We treated 48 patients with distal femoral tumors by resection and limb salvage with an uncemented megaprosthesis (Howmedica Modular Replacement System). Diagnoses included: 32 osteosarcomas, five chondrosarcomas, six giant cell tumors of the bone, three fibrosarcomas, and two Ewing's sarcomas. The mean follow-up was 5.6 years (2-10 years). The overall complication rate was 39%. Seven patients died of their disease, but none from complications related to the surgery. Five patients were revised to arthrodesis, and one required amputation because of complications. The mean postoperative Musculoskeletal Tumor Society score (MSTS) score was 21 (6-28) for the remaining 35 patients. The most frequent complications were infection (14.6%) and aseptic loosening (4.8%). Ten-year survival of the prosthesis was 65%.

Les auteurs ont traité 48 patients atteints de tumeurs du fémur distal par résection et reconstruction avec une prothese non-cimentee (HMRS). Les diagnostics étaients : ostéosarcome 32, chondrosarcome 5, tumeur a cellules géantes 6, fibrosarcome 3, et sarcome d'Ewing 2. Le suivi moyen fut de 5.6 ans (2–10 ans). Le taux de complications global fut de 39%. Sept malades sont morts de la maladie tumorale, mais aucun de complications de la chirurgie. Cinq patients ont dû avoir une reprise pour arthrodèse et un patient a subi une amputation à cause de complications. Le score MSTS (musculo-skeletal tumor society) moyen fut 21 pour les autres. Les complications les plus fréquentes étaient l'infection (14.5%) et le descellement (4.8%). Le taux de survie de la prothese a 10 ans était de 65%.
