Abstract
We have analysed the results of 246 cases of distal femoral tumours treated by resection and prosthetic replacement between 1988 and 2002. Patient ages ranged from 6–67 years averaging 24 years; 133 were males. The most common tumour was osteosarcoma (67% of patients). The follow-up ranged from 2 to 14 years. Stage II tumours were seen in 72% of patients. The technique of sleeve resection of the quadriceps musculature was followed to achieve local clearance of the tumour. The prosthesis used was a rotating hinge custom mega-prosthesis manufactured locally. The functional result achieved was excellent or good in 87%; 86% of the patients had no evidence of disease, and 13% had died. The 10-year patient survival was 76.9%. Periprosthetic fracture and infection were the most common complications.
Résumé
Nous avons analysé les résultats de 246 cas de tumeurs fémorales distales traitées par résection et remplacement prothétique entre 1988 et 2002. L’âges des malades s’étendait de 6 à 67 ans avec une moyenne de 24 ans. Cent trente trois étaient des hommes. La tumeur la plus fréquente était l’ostéosarcome (67% des malades). Le suivi était de 2 à 14 années. Des tumeurs de stade II étaient présentes chez 72% des malades. La technique de résection a été conduite pour faire une ablation complète de la tumeur. La prothèse qui a été utilisée était une méga prothèse à charnière rotatoire fabriqué localement. Le résultat fonctionnel obtenu était excellent ou bon dans 87%. Quatre-vingt-six pourcent des malades n’avait pas d’évidence de maladie et 13% étaient morts. La survie à dix ans était de 76,9%. Les fractures périprothétiques et l’infection étaient les complications les plus fréquentes.
