ABSTRACT

Nine patients with the diagnosis of malign bone tumor of the proximal femur were treated with the wide surgical resection of tumor and reconstruction with modular megaprosthesis. Six of the patients were male and 3 were female with an average age of 64.1 years old. The mean length of proximal femoral resection was 13.1 cm. Modular megaprosthesis was applied with a cemented femoral stem and bipolar acetabuler component. Gluteus medius was attached to the prosthesis which surrounds soft tissues in all patients. At the end of the follow-up period, clinical evaluation of the patients was made according to the Musculoskeletal Tumor Society (MSTS) scoring system. One patient who died of causes related to the tumor was excluded from this study. The average follow- up period of the rest 8 patients was 19.8 months There wasn't any local reoccurence. The mean MSTS score was 23.75 (%79.2) at the end of the follow- up period. In the short-term period after surgery, one patient had recurrent dislocations and revision surgery was applied.
