Total Femoral Replacement for Complicated Echinococcus Infection

Abstract

Case: Osseous hydatidosis caused by Echinococcus is rare, especially in long bones. To the best of our knowledge, this is the third femoral hydatidosis case with successful osseous eradication through total femoral resection and total femoral megaprosthesis. Unlike the previous 2 cases, we uniquely illustrate recurrent soft-tissue hydatidosis episodes requiring additional hydatid resections for local control with no evidence of disease at final 16-year follow-up, the longest follow-up period of the 3 reported cases. Conclusion: Despite radical bone resection for osseous hydatidosis eradication, additional complex surgical interventions may be needed to locally control soft-tissue disease.

Cystic echinococcosis of the bone

“…However, this usually leaves an extensive bone defect with multiple reconstruction difficulties. Extensive or even total bone resection followed by massive skeletal allograft or mega-prosthetic replacement has been tried in femoral CE [49,50]. Moreover, prosthetic reconstruction as well as bone grafts can also be invaded by the disease.…”
