Abstract:
:Limb-sparing procedures utilizing endoprostheses improve both the quality of life and functional level of patients treated for primary bone sarcomas. Herein, we present the imaging findings of an uncommon cause of prosthetic failure, i. e., foreign body reaction, manifested by progressive multifocal osteolysis along the prosthetic femoral shaft.
