Intercalary endoprosthetic reconstruction for impending pathological fractures in patients with femoral diaphyseal bone metastases.

Improvement of the life expectancy in patients with metastatic bone tumors has increased the emphasis on preserving the function of affected limb. Between 2006 and 2008, we used custom-made endoprostheses in four patients to reconstruct femoral diaphyseal defects after excision of metastatic bone tumors. The mean age at operation was 65 years (55–78) and the median follow-up 10 months (4–17). Using the Musculoskeletal tumor society (MSTS) functional scoring system, the mean MSTS functional score was 67%. Local recurrence and mechanical loosening were not occurred. We conclude that diaphyseal endoprostheses in femoral bone offer a good clinical and functional outcome. [ABSTRACT FROM AUTHOR]
