Abstract
Six patients underwent wide segmental resection and limb salvage surgery for primary or metastatic bone tumors involving the diaphysis of the femur, the tibia and the humerus using a modular intramedullary diaphyseal segmental defect fixation system. There were 4 men and 2 women with a mean age of 62 years (range, 40 to 77 years).
Histological diagnosis included adamantinoma, dedifferentiated synovial sarcoma attached to the tibia, multiple myeloma, and metastatic renal cell carcinoma, myeloid carcinoma of the thyroid gland and metastatic adenocarcinoma of the stomach.
The mean follow-up was 16 months (range, 11 to 24 months). At the latest examination, 5 patients were free of local or distant disease; one patient had deceased with distant disease, without evidence of local recurrence. Revision surgery was necessary in one patient because of mechanical loosening of the proximal fixation of the prosthesis. The mean increase of the Enneking rating from the pre to the postoperative status was 87.82%.
The intramedullary diaphyseal segmental defect fixation system used herein is associated with a satisfactory functional and oncological outcome after wide resection of diaphyseal bone tumors.
