Multifocal osteolysis following limb-sparing procedures: imaging findings and a review of the literature

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.

Limb-sparing procedures: postoperative planar bone scan appearance

“…These abnormal bone scans accurately documented the complication in four of the eight events, but failed to reflect the event in the remaining four children, the case of one of whom was reported previously [4]. Serial imaging in these 11 patients showed prior abnormal avidity in seven patients; however, prior scans were normal in the other four (Fig.…”
