Purpose:To compare clinical outcomes of the tumor prosthetic replacement and osteosynthetic fixation for pathologic fracture of skeletal metastatic lesion of the proximal femur.
Materials and Methods :From 1994 May to 2009 May, medical records of 22 patients who underwent tumor prosthetic replacement with tumor resection (group 1) and 15 others (16 hips) who underwent osteosynthetic fixation without tumor resection (group 2) were reviewed. The mean age of overall patients were 59 (group 1) and 60 (group 2). Mean follow up periods were 23 and 11 months. The oncological and functional results were evaluated with Kaplan-Meier methods and Musculoskeletal Tumor Society (MSTS) scoring system, 1993. The statistical evaluation was assessed with Log rank test and t-test.
Results:The mean survival periods were 24 months in group 1 and 11months in group 2. The 1 year survival rates were 86% in group 1 and 50 % in group 2, and 2 year survival rates were 29.7% in group 1 and 9.4% in group 2. The mean MSTS functional score were 26.4 (19-30), 87.9% in group 1 and 15.3 (10-23), 51.0% in group 2.
Conclusion:The results of tumor resection and prosthetic replacement in selected cases was better than osteosynthetic fixation without tumor resection for metastatic bone tumors around proximal femur in oncological and functional aspects.
